Just Temperature:

The U.S. has just experienced an intense heat event with many records falling in the eastern half of the U.S. Here is Chris Burt’s post on the historic event. There is an excellent discussion of this event and its relation to a warming climate by Andrew Freedman at Climate Central. (Global Warming May Have Fueled March Heat Odds) I have a talk to give next week, and I am sure that the heat will contribute to questions. A question that has been put to me frequently in the past weeks is that should we expect such high temperatures in the future?

Usually when I talk about evidence of a warming, I talk about coherent and convergent evidence. That is, one can’t just look at the global surface temperature data and state that the planet has warmed. But if you look at the surface temperature data along with many other sources of data, then one finds that the evidence of warming is overwhelming. If you add the impacts of this warming to ecosystems, for example, the observations that spring is coming earlier over most of the land area in the Northern Hemisphere, then the evidence becomes smothering. For me and many others this evidence of warming is convincing, but it relies on pulling together information from many sources, explaining their relationships, and presentation of the information. So as people have asked me about the heat in Michigan and Maine this past week, I have thought of what I could do with just temperature. Here is the thread that I put together.

The last month when the global mean monthly average was below the 20th century average was February 1985. Here is a picture of the difference from the 100 year average of temperature data from each February. It has been 324 months since there was a month below the global average temperature. (Not 324 Februarys, 324 consecutive months.) Looking at the graph, the Southern Hemisphere, which is dominated by the ocean, goes back into the 1970s. There have been Februarys in the Northern Hemisphere with little blips below average.

Figure 1: February monthly difference from a 20th century average of all Februarys. From the National Climatic Data Center.

The average in this figure is based on the entire 20th century. Therefore, if you look at the record during the 20th century, there is a balance between the warm and the cold months. This fact comes directly from the definition of calculating the differences from an average. There is a famous 1930s warm period. This warm period is present in the February time series, but compared with a later span centered around 1960, this period in not as intense. A prominent characteristic of the graph is that on the left, in the first part of the 20th century, it is cooler than the average and on the right, the here and now, it is warmer.

To go along with the February graph, I have placed the graph from August 2011. The main part of the story, that in 1900 it was cooler than in 2000 remains the same. Here, in the Northern Hemisphere summer, the 1930s warm period is more prominent and more global than in February. In is easy to conclude from this figure that the spatial extent and the temporal persistent of the current warming are both far larger than in the spurt of warmth of the 1930s.

Figure 2: August monthly difference from a 20th century average of all Augusts. From the National Climatic Data Center.

I started this article with the question is the current heat event in the U.S. what we can expect in the future? Taking this simple argument, looking at the average for the past, almost 30 years, it seems reasonable to expect it be warm. And given, the relentless increase of carbon dioxide in the atmosphere, we should expect it to be warmer in the future. To expect otherwise would be betting against the average.

Betting against the average – the next plot, Figure 3, is adapted from a 2009 paper by Jerry Meehl and a host of other authors. (Original Paper, Paper Discussion from NCAR ) What this figure shows, for the U.S., is the number of new record highs divided by the number of record lows – the ratio of highs to lows. In a simplistic, intuitive way, if the average temperature where staying the same, then one would expect the number of new record highs and the number of new record lows to be about the same. What is seen in the figure is as we go from the 1980s to the 1990s to the 2000s, there is trend of record highs out numbering record lows by a factor of 2 to 1. Comparing this with Figures 1 and 2, this evolution of new record highs outpacing new record lows occurs during the time when there has not been a month below the global 20th century average.

Figure 3: Adapted from Meehl et al. (2009) the ratio of U.S. record highs and record lows by decade.

The next figure I show is another version of the global difference figure. This one is calculated as differences from 1950 onwards in order to overlap with the data from the Climate Prediction Center that identify El Nino and La Nina Cycles. El Nino and La Nina are names given to frequently occurring patterns of variation that are concentrated in the tropical Pacific Ocean, but that change the average temperature of Earth for about a year. When there is an El Nino then the globe is warmer and when there is a La Nina the globe is cooler.

Figure 4: Global temperature differences with El Nino (warm) and La Nina (cool) years marked. From National Climatic Data Center.

Looking first at the La Nina years, 1985, the last year when the Earth was cooler that the 20th century average was a La Nina year. One could say that this was the last year when the variation associated with La Nina was strong enough to counter the warming trend enough for the Earth to appear “cool.” What is striking is that the La Nina years in the past three decades are systematically warming. This suggests that in the La Nina cool period, we are seeing a warmer and warmer background, average, temperature evolving.

The warm phase of this variation does not paint as easy a picture. The very strong 1997-1998 El Nino famously raised the Earth’s temperature to a point that many argue was the warmest year observed. The subsequent El Nino events are not as strong as the 1997-1998 El Nino, and each one has temperature maximum that flirts with the 1998 maximum. It is important to note that in 1998 the entire positive anomaly of temperature was not due to the presence of El Nino. The El Nino events take place on a background of increasing temperature, and each event is a burst towards new historic highs in temperature. It is useful to look back earlier in the graph, say 1970 and earlier, to get an idea of the size of variation that can be associated with El Nino and La Nina.

Returning again to the question posed in the beginning, can we expect to regularly see such warm temperatures going forward? Yes, it makes sense that we will see more and more record high temperatures. To not expect that is to bet against the emerging observed trend of warmer and warmer temperatures that is a metric of the warming climate.

I will finish this just temperature story with a map of the Plant Hardiness Zones. Here is the official version from the US Department of Agriculture with an service that lets you pick out your zip code. I show a map of Michigan. In 1990 the green zones, 6, were down around the Ohio River in southern Ohio. This is a measure of not only warming, but also of the definitive changes in the onset of spring. The Washington Post has an excellent graphic that shows the changes between 1990 and 2012.

Figure 5: Plant hardiness zones in Michigan for 2012. From US Department of Agriculture.

We have just experienced in the U.S. a record extreme heat event. This raises the natural questions of climate, weather, and climate change. I have linked a couple of excellent discussions of these issues in the opening paragraph. What I have done in my article is to focus simply on temperature. I have laid out a thread that starts from the globe and the remarkable observation that we have not seen a month below the 20th century global average in more than 25 years. This I followed with the observation that we are in a time when we are setting more than twice as many record highs as record lows. After that I discussed the role of one of the most prominent forms of planetary temperature variations, El Nino and La Nina. The compelling point from this graph was that in the past 30 years during the cool phase, La Nina, the planet shows a warming trend. Finally, I introduce the plant hardiness zones, which show warmer winters, and can be translated to earlier springs. So the question that has been posed to me last week, can we expect such high temperatures in the future? Yes. If we use our experience and observations for the basis of decision making, then the rational answer is yes. We will see more records. We will see an earlier spring. We will see warmer times.

Quoting Birthmark: I read somewhere that the doors of the trailers being open might be responsible. Sounds plausible enough to me. That is an assertion that I've seen only on blogs. Again I ask, if you have a link to a peer-reviewed rebuttal I'll be most grateful. Until then I have to view such an assertion as unsubstantiated. No other way to work it. That's the very year that I predicted that we'd see an ice-free Arctic. Barring asteroid impact, volcanoes, nuclear war, etc., I'm pretty sure that I'll be much, much closer to correct than your friend. Okay. Say the PDO/AMO behave exactly as you expect. What will keep the global temperature from plummeting as your friend suggests? But the fact is that they are not correct. If they were correct, then the climate of Earth is impossible to explain through a vast majority of its history. New is dicey when it contradicts the body of knowledge. Such a paper needs to be taken with a large of amount of salt until it can be verified. (Yes, medical science, I'm lookin' at you! The wording may (or may not) be problematic, given the fact that they were questioning scientists in their area of expertise. It's unlikely that many were confused by the questions, so I stand by my "vast majority" statement until it can be refuted in the peer-reviewed reputable journals. Speaking of which, the overwhelming majority of peer-reviewed science agrees rather well with the results of the study. A better question is what's so wrong with it that Scarfetta won't submit it for peer-review? If he's really got the goods then he should publish. He hasn't to my knowledge. The actual label for Figure 7 is "Sensitivity of the solution for (^Tsun)(t) to different values for the parameters listed in Table 6 and for different ways of combining PMOD and Lean et al. [1995] and Lean [2000] S." So I don't think it's saying what you think it's saying. Link to Benestad and Schmidt. Bah! I'll bet you're a Virgo, aren't you? :^D Why should anyone care that a useless widget appears to show something? SkS pretty convincingly demonstrated that the widget fails very quickly when tested against historical values. So the chances are extremely high that Scafetta was just playing games with statistics to get the answer he wanted. Um, that's what he did...or rather he stopped just short of it and allowed you to make the final jump. Plausible deniability. Because they were specially chosen to do so...providing that they really do display such a trend. Again, it's a blog post. If he thinks he's got something then he should publish. Didn't forget. It's just not that important. I can get cooling anywhere the Sun isn't shining. However, getting warming without the Sun is pretty difficult, don't you agree? Doesn't need to be homogenous since local effects are also important. It just needs to be a net warming...which it is. Goodness gracious me! Do you think that uncertainty is limited to climate science?! If so, then please take this opportunity to disabuse yourself of that notion. All sciences are rife with uncertainty. It's one of science's strengths, and charms, imo. As for the uncertainty in this case: Well, the one thing we can be certain of is that the Sun cannot be responsible for the winter warming in Antarctica and the Arctic. That was rather my point. Of course. But in order for that to happen, the tropics first have to warm. The tropics are not warming nearly fast enough to indicate that the Sun is involved. Now you're rationalizing. The albedo of the high latitudes in winter doesn't matter. Yet they are displaying some of their most dramatic warming in months when the Sun isn't visible. There have been many studies of clouds' effects on climate. They certainly play a part, but not a crucial one. And if you're shuffling towards Lindzen's iris hypothesis...well, I just hope that you're not since it's an abject failure. CO2 concentration has increased by around 40% in the last 150 years or so. It is extremely likely that CO2 is the major cause of the warming. The situation at the poles demonstrates that the current warming is unrelated to the Sun in any major way. That can change, one way or the other, but at the current time the Sun simply can't be responsible for very much of the warming. Not even if we really, really want it to be. "+" 1.37823 X 10^23, +/- 1.5%. I removed some of your brakes (breaks) and achieved a shorter stopping point. No place else, but on the HTML highway, will you achieve these same results! ;-) How about this? Spaces removed to conserve space. ;-) I hope that everyone has a sense of humor, 'cause I am tired today. Member Since: 24 août 2010 Posts: 0 Comments: 4139

Quoting Some1Has2BtheRookie: Yes, it is easy to get caught up in a blog mode. CO2 was around 355 ppm in 1990. Today's CO2 level is over 393 ppm. This is nearly a 40 point increase over 21 years. This is why I suggest that the next strong, extended period of solar activity, in conjunction with a strong, extended El Nino, will probably bring about a warming of the climate beyond what we have previously observed and beyond what would be expected of such an event. Yes, we will have to wait to see if this comes to be, but I think the odds will not be in our favor. That's certainly a possibility, if I am underestimating CO2 as a radiative forcing. Just remember, the sensitivity of the climate is very low, so you may be breathing a sigh of relief when the next El Nino does not warm the planet as much as you would have expected. The El Nino would not be that strong if one were to form, because of a -PDO, so not as much energy in the oceans would be transferred to the atmosphere to warm the surface and LT up. Of course, a -PDO will also raise Cloud Cover slightly. That in conjunction with the AMO should keep Global temperatures from rising, although the radiative forcing from CO2 is not going away, so if there are no other natural factors pointing the other way, there could possibly be very large amounts of warming for 30 or so years after this hiatus. The latest MJO wave removed a lot of heat from the oceans as well through convective overturning, so the next Nino has less heat to exchange with the atmosphere than it did before. Quoting Some1Has2BtheRookie: I would suggest that my reasoning is no so flawed. We know that there was rain for as long as there has been a recorded history. My making an assumption that we had clouds before 1983 is therefore not a flawed assumption. No clouds, no rain. There have been historical floods, even Biblical floods, before 1983. Yes, there have been clouds in the past because evaporation and condensation have always occured in the past. There could have been significantly MORE clouds in the past, and they could have decreased significantly, contributing to a large portion of the warming observed over the last 100 years. Quoting Some1Has2BtheRookie: I agree with you on this, but now, cloud cover in the tropics, prior to 1983, may very well come into play. The equatorial regions of the Atlantic and the Pacific oceans covers a large area of the tropics. While there were ships traversing these areas and they did note the weather conditions, most shipping lanes are well north or south of the Equator. WWII warships observations could probably provide us more data the the then tropical clouds than most commercial shipping lanes could, but this is just my guess. Even the vast majority of commercial air traffic lanes are well north of the tropics. Still, we are not completely void of any information from the tropics prior to 1983. We're not completely void, but we're almost completely void. ;) If you were to walk on a wooden bridge that had one or two wooden planks on it, it's 100 feet across, and it's 200 feet off the ground, would you walk on it? That's how bad the data is in the past. Quoting Some1Has2BtheRookie: I am afraid that I am not versed on this and therefore I could not even give you an educated guess on this. Once I have studied this some, I may feel comfortable enough to make a comment on this. Look at the peer reviewed paper I posted. There seems to be a solid link between cloud cover and direct variations in solar activity. Therefore, decreasing Cloud Cover could signify that the ACRIM dataset is correct. Quoting Some1Has2BtheRookie: Not even close. When you look for the reasons that drive our climate, you would be foolish to ignore the Laws of Physics, the greenhouse effect and basic Chemistry. I did not decide what these are either. ... I am old, but not that old. I do take the GHE into account, it may be the driver of the climate in the future for all I know. It depends on how high solar activity can go. Quoting Some1Has2BtheRookie: I would have to go back and check, but I believe that I said that CO2 is the initiator of the climate change. I have seen no other evidence to the contrary that a rising CO2 level also saw the warming the warming of the climate. Other players, certainly, have had their influence, but you cannot just dismiss the rising CO2 levels either. I can't dismiss CO2 as a factor, but you can't dismiss the papers I posted about the TSI in the ACRIM composite being able to explain most of the warming over the last 30 years. ;) Quoting Some1Has2BtheRookie: That is a rather strong claim to make based solely on past climate changes. When there have been past climate changes it has usually been the result of solar variations, orbital changes, a change in the tilt of Earth's axis, massive volcanic eruptions, a speed up in tectonic plate movement, increased and more dispersed land area causing a decreased open waters, meteor/asteroid strikes and other greenhouse gases in the atmosphere. So the sensitivity of the Climate has somehow changed now than it was in the past? Quoting Some1Has2BtheRookie: Seven years is too short of a time frame to show any long term trends. We need 23 years more data to see a long term trend. Yes, on this, it is wait and see. BTW, should you choose to excel at your future career, then I suggest to not use Spencer as a source. Spencer has long been known to jump the gun on many of his studies. Just saying. In the Climate models, the long term feedbacks diagnosed by Forster and Taylor had the same slope as the linear striations. Member Since: 1 avril 2010 Posts: 9 Comments: 2594

Quoting percylives: It feels better to have done it though. Or are you writing to avoid learning about your own area? Still haven't asked around to see if your town is getting warmer too. Living in ignorance doesn't appear to be your style. You might be right though. It is very unsettling. Once you find out that warming is occurring in the neighborhood and you project forward all kinds of peaceful assumptions get smashed. You start to wonder if your grandchildren's health and well-being will be compromised by that trip to London to see the Olympics. Drat! ;>) Well warming has always been better for us as a species than cooling has been in past history. That may change if we warm significantly in the future, and the negative effects of warming become evident. I am obsessed with Climate Change, and I just want to debate Climate Science and want all of the uncertainties about the science to be known by everyone. I am all for Solar Energy as I have stated before. That's all. Member Since: 1 avril 2010 Posts: 9 Comments: 2594

Quoting greentortuloni: Denialists counter this argument with (as you stated) absurd arguments about the cost of changing to a renewable infrastructure. Since you agree that we should change to renewable infrastructure as soon as possible, this leaves only the academic reason for your arguments. While your argument may be technically sweet to you, the result is counter to the progress that you want to occur. So I don't understand your motivation. The best I can come up with is some Ralph Naderish/Tea Partish idea of principle regardless of effects... but you seem too smart for that. So what is your motivation for posting? My reason for posting here is to debate Climate Science. My reason is not to prevent green energy from passing the legislation. My reason is because I looked at the science and the evidence, and I found that there were tremendous uncertainties that need to be resolved before anyone can confidently say that "most of the warming over the last 50 years can be attributed to anthropogenic Greenhouse Gases." Is that a bad thing to look at the evidence for one's self and make independent conclusions and hypotheses off of the evidence? A lot of people try and somehow link the future of Energy in America to Global Warming. People will use this as an excuse that pollution is not a problem and doesn't need to be adressed. I get it. It's unfortunate that it's hard to look at the evidence from an objective viewpoint because the future of America's Energy in part has to do with if it is bad for us. It most certainly is. The amount of pollution that we put into the air is incredible, and it needs to be stopped. It's unfortunate that big energy companies use that Global Warming is not a problem/it's not man-made to try and convince Congress that no action is required on our pollution. It's disgusting, like pollution. Member Since: 1 avril 2010 Posts: 9 Comments: 2594

Quoting Neapolitan: The deeper and more prolonged the La Nina, the more energy is stored in the Earth's heat sink--that is, the oceans. And this past La Nina was a doozy, so a lot of heat was stuffed into the bank, so to speak. As the earth transitions to an El Nino--even a moderate one--some of that heat will be withdrawn from the bank and released into the atmosphere, so surface temperatures will rise. And rise. And rise Some of the heat from the oceans has already been transferred to the atmosphere via convective overturning with the MJO wave in Octant 7, so I wouldn't count on it. I wouldn't count on it with a -PDO creating more Cloud Cover globally, and making the El Nino weaker. Quoting Neapolitan: When you say "Global Temperatures will come crashing back down" should MJO move into the correct octant, just how deep a crash do you envision? -0.1? -0.2? Deeper? The coolest temp the world has seen in the past 11 years or so was that -0.3 in January of 2008--and it's only reached that low three months in total since 1993 (making it all the more puzzling that Bastardi and D'Aleo would have predicted it for this month). Probably about the same change in temperature as from February to March. The MJO is primarily responsible for these large fluctuations in temperature from month to month. Quoting Neapolitan: I will bet you a lot of money--and that friend of yours even more--that you're both dreadfully wrong. The '10s will be warmer than the '00s, as the '00s were warmer than the 90s, and as the 90s were warmer than the 80s, and the 80s were warmer than the 70s. And the 20s will be warmer than the 10s, while the 30s will be warmer than the 20s. And 20 years from now I imagine part of you will remember this and other discussions like it and wonder, "What was I thinking?" I wouldn't be too sure about that. We're into out 15th year where temperatures have not risen, according to HadCruT4, and we should probably not warm for another 30 or so years, just based off of the PDO/AMO alone.

Quoting Snowlover123: We're into out 15th year where temperatures have not risen, according to HadCruT4, and we should probably not warm for another 30 or so years, just based off of the PDO/AMO alone. Um, no. We're not. The 2000s were warmer than the 1990s, for one thing. But even Hadcrut 3 shows warming over the last 15 years (1997-2011): So, there is warming over the last 15 years, though it probably isn't statistically significant --nor should it be for such a short time frame. Hadcrut3's well known cold bias is the reason Hadcrut4 exists. So, it's likely that the warming is at least as large in Hadcrut 4. Member Since: 30 octobre 2005 Posts: 0 Comments: 1805

Good evening, Snowlover123. Your first graphic is by Dr. Roy Spencer. This is the same Spencer I have warned you about. Dr. Roy Spencer has some excellent credentials and has done some extensive work with John Christy. The second graphic is by Jennifer Marohasy. She is a biologist. ... Sorry, but I cannot even read the graphic. You say that you looking for all the scientific evidence that you can find concerning AGW. I suggest that you have been looking for love, in all the wrong places. Please, do some serious research on Dr. Roy Spencer, John Christy and Jennifer Marohsay before you use them to try to gain the scientific evidence you seek. Let me know what you find. You may also come across a Christopher Monckton while trying to seek "evidence". Christopher Monckton Revealed Member Since: 24 août 2010 Posts: 0 Comments: 4139

The problem I have is that this argument seems to be a bit out of control. I don't see this being debated well, in all honesty. It seems to be a war of attrition voer who has the most resources to quote sources and blah blah blah. It seems like something Lord Dorwin wuold have loved - on both sides, mind you, I am not singling you out for attack. That characterization I just gave is unjust fro a variety of reasons. However, on a pop culture level it is true: denialists, who are not scientifically literate for the msot part, will jump on your debates, quote them out of context, etc.. In short, you are causing more damage. Your statements like "Well warming has always been better for us as a species than cooling has been in past history" doesn't do much to sway my opinion either. So what is the option? Do I wish censorship? No, of course not. However, being a sceptic in this environment does damage. There is no way around that point either. It is the equivilent of say "No Fire" in a theatre that may or may not be burning. Unless you are sure there is no fire, why say anything? What would you suggest to someone in your shoes but with a different subject (i.e. a meteor that may or may not be headed to earth)? Member Since: 5 juin 2006 Posts: 0 Comments: 1198

As others have already noted, that is absolutely not true by any stretch of the imagination. Again, it's the epitome of cherry-picking to begin any temperature on the anomalously warm year of 1998, which "skeptics" have been doing now since, well, about 1999. "It hasn't warmed for the past 2 years," they said. Then "It hasn't warmed for the past 5 years." Then "It hasn't warmed for the past 7 years." Then "It hasn't warmed for the past 10 years." Then "It hasn't warmed for the past 15 years." The next El Nino year--perhaps 2013--will prove to be warmer than 1998, and I'm sure that will start over; in 2015, we'll again hear, "Well, it hasn't warmed for the past 2 years." ;-) Member Since: 8 novembre 2009 Posts: 4 Comments: 11306

Elvis briefly brought this up in an earlier comment, but I thought it worth a second mention: according to an article in the journal Nature, CO2 did lead the warming after a jump start from Milankovich cycles. Abstract: Past extreme warming events linked to massive carbon release from thawing permafrost Between about 55.5 and 52 million years ago, Earth experienced a series of sudden and extreme global warming events (hyperthermals) superimposed on a long-term warming trend. The first and largest of these events, the Palaeocene–Eocene Thermal Maximum (PETM), is characterized by a massive input of carbon, ocean acidification and an increase in global temperature of about 5 C within a few thousand years. Although various explanations for the PETM have been proposed, a satisfactory model that accounts for the source, magnitude and timing of carbon release at the PETM and successive hyperthermals remains elusive. Here we use a new astronomically calibrated cyclostratigraphic record from central Italy to show that the Early Eocene hyperthermals occurred during orbits with a combination of high eccentricity and high obliquity. Corresponding climate–ecosystem–soil simulations accounting for rising concentrations of background greenhouse gases8 and orbital forcing show that the magnitude and timing of the PETM and subsequent hyperthermals can be explained by the orbitally triggered decomposition of soil organic carbon in circum-Arctic and Antarctic terrestrial permafrost. This massive carbon reservoir had the potential to repeatedly release thousands of petagrams (1015 grams) of carbon to the atmosphere–ocean system, once a long-term warming threshold had been reached just before the PETM. Replenishment of permafrost soil carbon stocks following peak warming probably contributed to the rapid recovery from each event, while providing a sensitive carbon reservoir for the next hyperthermal. As background temperatures continued to rise following the PETM, the areal extent of permafrost steadily declined, resulting in an incrementally smaller available carbon pool and smaller hyperthermals at each successive orbital forcing maximum. A mechanism linking Earth’s orbital properties with release of soil carbon from permafrost provides a unifying model accounting for the salient features of the hyperthermals The article's lead author, Rob DeConto, clarified the article in a press release: "'The standard hypothesis has been that the source of carbon was in the ocean, in the form of frozen methane gas in ocean-floor sediments,' DeConto says. 'We are instead ascribing the carbon source to the continents, in polar latitudes where permafrost can store massive amounts of carbon that can be released as CO2 when the permafrost thaws.' The new view is supported by calculations estimating interactions of variables such as greenhouse gas levels, changes in the Earth’s tilt and orbit, ancient distributions of vegetation, and carbon stored in rocks and in frozen soil. While the amounts of carbon involved in the ancient soil-thaw scenarios was likely much greater than today, implications of the study appear dire for the long-term future as polar permafrost carbon deposits have begun to thaw due to burning fossil-fuels, DeConto adds. 'Similar dynamics are at play today. Global warming is degrading permafrost in the north polar regions, thawing frozen organic matter, which will decay to release CO2 and methane into the atmosphere. This will only exacerbate future warming in a positive feedback loop.'" Member Since: 8 novembre 2009 Posts: 4 Comments: 11306

Quoting greentortuloni: If this was an academic question only, I wouldn't even be on this blog. I think a lot of other people feel the same way. The problem I have is that this argument seems to be a bit out of control. I don't see this being debated well, in all honesty. It seems to be a war of attrition voer who has the most resources to quote sources and blah blah blah. It seems like something Lord Dorwin wuold have loved - on both sides, mind you, I am not singling you out for attack. That characterization I just gave is unjust fro a variety of reasons. However, on a pop culture level it is true: denialists, who are not scientifically literate for the msot part, will jump on your debates, quote them out of context, etc.. In short, you are causing more damage. Your statements like "Well warming has always been better for us as a species than cooling has been in past history" doesn't do much to sway my opinion either. So what is the option? Do I wish censorship? No, of course not. However, being a sceptic in this environment does damage. There is no way around that point either. It is the equivilent of say "No Fire" in a theatre that may or may not be burning. Unless you are sure there is no fire, why say anything? What would you suggest to someone in your shoes but with a different subject (i.e. a meteor that may or may not be headed to earth)? There are skeptics like me who want clean energy.

A new paper that was published quite recently (another one of those "dicey" papers since it's new.) It found a statistically significant decrease in Cloud Cover from 1954-2005 (which could further support the ACRIM composite, since Solar activity is directly and is significantly correlated to cloud cover changes. The author of this paper ruled out the cause of this decrease being due to anthropogenic aerosoles. And the abstract is available here. Quoting Paper: An updated analysis of cloud cover during 1954-2005 in China was performed using homogeneous cloud cover data from 314 stations. Long-term changes in frequencies of different cloud cover categories and their contributions to long-term changes in cloud cover were assessed. Furthermore, aerosol effects on cloud cover trends were discussed based on comparison of cloud cover trends in polluted and mildly polluted regions. Frequencies of clear sky (cloud cover 80%) were observed to increase by ~2.2 days and decrease by ~3.3 days per decade, respectively, which accounts for ~80% of cloud cover reduction. Larger decreasing trends in cloud cover due to larger increase in clear sky frequency and larger decreases in overcast frequency were observed at stations with lower aerosol optical depth. There is no significant difference in trends regarding cloud cover, clear sky frequency, and overcast frequency between mountain and plain stations. These results are inconsistent with our expectation that larger decreasing trends in cloud cover should have been observed in regions with higher aerosol loading where more aerosols could lead to stronger obscuring effect on ground observation of cloud cover and stronger radiative effect as compared with the mildly polluted regions. Aerosol effect on decreasing cloud cover in China appear not to be supported by this analysis and therefore, further study on this issue is required. (From the summary) Significant decline in cloud cover with trend of 1.6% per decade during 1954-2005 was derived. Occurrences of clear sky (cloud cover 80 %) were observed to increase and decline by 2.2 days per decade and 3.3 days per decade, respectively. Approximately 80% of overall trend of cloud cover is attributable to an increase in clear-sky days and a decline in overcast days. Member Since: 1 avril 2010 Posts: 9 Comments: 2594

From RSOE EDIS "04.04.2012 12:48:59 \| TG Daily Scientists studying coral off the coast of Tahiti have linked a collapse of the world's ice sheets 14,600 years ago to a sudden 14-meter rise in global sea-levels. Until now, the date of the sea-level rise was unknown. But the new evidence dates it to 14,650 to 14,310 years ago, just when the Earth was experiencing a period of rapid climate change known as the Bolling warming. During this period, high latitudes of the Northern hemisphere warmed as much as 15 degrees Celsius in less than 350 years - possibly much more quickly. "It is vital that we look into Earth's geological past to understand rare but high impact events, such as the collapse of giant ice sheets that occurred 14,600 years ago,' says Dr Alex Thomas of Oxford University. "Our work gives a window onto an extreme event in which deglaciation coincided with a dramatic and rapid rise in global sea levels - an ancient 'mega flood'. Sea level rose more than ten times more quickly than it is rising now!" The Tahitian coral is helpful because samples thousands of years old can be dated to within plus or minus 30 years. And because Tahiti is an ocean island, far away from major ice sheets, it's close to the average of sea levels across the globe. While it's gradually subsiding into the ocean, this is happening at a steady pace that can easily be adjusted for. What exactly caused the Bolling warming is unclear; right now, the leading theory is that the ocean's circulation changed so that more heat was transported into Northern latitudes. The new sea-level evidence suggests that a lot of the water causing the sea-level rise must have come from melting of the ice sheets in Antarctica, which sent a 'pulse' of freshwater around the globe. "This is an excellent test bed for climate models: if they can reproduce this extraordinary event, it will improve confidence that they can also predict future change accurately," says Thomas." If I'm reading this right they're saying the Earth experienced 14 meters of sea level rise in approximately 340 years. Now that will mess up your millennium.

From RSOE EDIS "04.04.2012 12:37:58 \| www.wwno.org Tulane researchers say sea levels are rising faster than expected. Gulf Coast communities from the Florida Panhandle to East Texas are most at risk. One of the authors of the Tulane study says the Earth crust underneath the Mississippi Delta is sinking, but not as fast as previously believed. But Torbjorn Tornqvist (tohr-bâ-yorn torn-kwist) says the Gulf of Mexico is rising faster than feared, and washing away more shoreline. “Sea level in the past century has been rising about five times faster than it did in, say, the 1,000-year period that preceded it.” Tornqvist says researchers performed extensive testing in southwest Louisiana, coring and collecting samples, conducting surveys and gathering accurate elevation numbers. “Unfortunately if we look at the amount of sea level rise along the Gulf Coast in the last century it’s been somewhere a little bit over eight inches. It’s very, very likely that in the next century it’s going to be quite a bit more. And the more pessimistic predictions think of rates of magnitudes that could be as much as three to five feet.” Tornqvist says climate change that’s melting ice caps must now be considered a major local and international concern because sea levels will certainly keep rising. “States like Louisiana that are arguably going to be the first victims within the United States of climate change – and in fact you could say that we already are – we really need to step forward and take the lead in this.” The study is published in the journal “Earth and Planetary Science Letters.”" This fellow is saying you Louisiana folks need to keep for flood insurance current.

I believe that what greentortuloni is trying to say is that if you do not have strong evidence that would invalidate the AGWT, then conversations that only raise doubt will prove counter productive.

Post 279: I Was a Paid Internet Shill Speaking of shills. ..Actual Bill Ayers Rant: Why Do ‘Uniformed Military’ Get to Board Planes First? By Benny Johnson \| The Blaze – 21 hrs ago.. Bill Ayers and his wife Bernadine Dohrn paid an impromptu visit to Occupy Wall Street in New York City Friday, bestowing their advice to a gaggle of elated protesters. Ayers and Dohrn, former leaders of the violent leftist Weather Underground group, were greeted like rock stars at the camp. A reception, you'll soon hear, they wouldn't want to give the nation's military members. The couple passed along protesting and anti-military nuggets of wisdom to the youngsters who received it in good spirits. For example, the former confidants to President Obama made sure to mention that America is "a declining power" that must depend on "a militarized 1%."

NASA Admits No CO2-AGW Warming In USA; Why Is World Warming and Not U.S.? It comes as not even a tiny surprize that when someone asks “Where does all the CO2 go in an ice age?” that the answer is “The Ocean“. We already know temperatures rise 800 years before CO2 levels (Caillon 2003), and we know the oceans contain 50 times as much CO2 as the sky. Moreover, basic chemistry tells us that CO2 (like all gases) will dissolve better in cold water, and be released as the water warms. To cap it all off, the deep abyss of the oceans turns over once every millenia or so (which fits loosely with the “lag” between temperature and CO2 levels). But you would think this new research was solving a deep mystery, rather than confirming what most sane knowledgeable people would expect.

Quoting Snowlover123: There are skeptics like me who want clean energy. Not very many, but there are other skeptics like me out there. Snowlover. You are a denier and not a skeptic. Genuine skeptics consider all the evidence in their search for the truth. Deniers, on the other hand, refuse to accept any evidence that conflicts with their pre-determined views and therefore you are a denier. You dismiss research by scientist, for example Solanki who is a very knowledgeable scientist, and instead cherry-picking scientists that fit your "theory". Scientists, who have been proven wrong time after time after time, for example long wrong climate science disinformer Roy Spencer and long wrong Scafetta the widget man. You are cherry-picking graphs that fit your theory. Poorly made graphs which one can see directly is not taken from a scientific paper, but instead created by some denier at some anti-science blog. You give us links to paper which is only based on cloud cover over China or only 7 Spanish stations etc. Not global measurements. You pick out a few sentences from a paper and make your own interpretation on that basis. You say that I haven't read your links. I have done that but I am convinced, that you have not read what it says in the papers I and others have given you because these papers conflict with your pre-determined view. Many independent tests indicate the PMOD composite is the more accurate TSI reconstruction. Here’s one more, and also the last paper about this issue from me. It's the paper by Lockwood et al. 2008. Look at the image below. If the PMOD composite was correct, the data points should be clustered around the ideal (light blue) line. If ACRIM was correct, a second population should appear aligned along the dashed blue line. It shows no such second population. From the conclusion in the paper Lockwood 2008: ”Here, we point out that the TSI modelling of Wenzler et al. (2006) from ground-based magnetograms is also consistent with the PMOD composite and inconsistent with ACRIM and IRMB. The great accuracy of this modelling, and the fact that the facular filling factor is the only free parameter, means that it provides an excellent test. In addition, we point out that the ACRIM composite generates some curious phenomena that would need explanation. For example, if the ACRIM composite were to be correct, the strong negative correlation between TSI and GCR fluxes over the solar cycle, for which we have a physical explanation, would reverse polarity on longer time scales for reasons we do not yet understand. This would invalidate almost all previous evidence for solar effects on climate on time scales longer than the solar cycle. We have also shown that the effect of smoothing time constant cannot be a possible source of the divergent trends in air surface temperature and solar inputs described in paper 1. Hence, like many authors before us, we conclude there is no credible way that the recent rise in air surface temperature can be attributed to solar effects.” Here is the paper. It is not the sun. In the last 35 years of global warming, sun and climate have been going in opposite directions. There is no correlation between cosmic rays and global temperatures over the last 30 years of global warming. PDO, AMO, ENSO, MJO, NAO, AO, SOI are natural oscillations and examples of internal variability, not external radiative forcing. They're not capable of causing a long-term warming trend, just short-term temperature variations. 97% of the world's scientists agree that humans are causing global warming due to CO2 emissions. Observations and direct measurement confirm that CO2 is currently the main driver of climate change. The global temperature is still rising and has not been flat the last 15 years. Antarctica is losing land ice at an accelerating rate. Etc. etc. etc. As I told you before, as long as you take your information from anti-scientific blogs you will have a hard time getting a Ph.D. in atmospheric science. Open your eyes and start over. Learn the basic physics and chemistry so you can recognize bad research. Take a broader view, a single paper must also be seen in the context of the full body of peer-reviewed research. If you do that, I am convinced it will go better for you. You will also discover that scientists know more about science than you think. They know a lot. ;) Member Since: 22 novembre 2010 Posts: 0 Comments: 796

Quoting PurpleDrank: You pick out a few sentences from a paper and make your own interpretation on that basis. so does NBC nightly news Ah, Drank. That just is not a fair thing to say at all. OK, it is probably true, but hardly fair that you would only point out NBC. I strongly suspect that any media outlet, that depends on advertising dollars, is going to gear their coverage towards what the advertisers want to hear, with a modicum of truth given to the news. Some, more than others, will allow the advertisers a certain degree of control over the actual content. ... Are you able to think of an examples of this? Where ya been, Drank?

Quoting Xandra: Snowlover. You are a denier and not a skeptic. Genuine skeptics consider all the evidence in their search for the truth. Deniers, on the other hand, refuse to accept any evidence that conflicts with their pre-determined views and therefore you are a denier. You dismiss research by scientist, for example Solanki who is a very knowledgeable scientist, and instead cherry-picking scientists that fit your "theory". Scientists, who have been proven wrong time after time after time, for example long wrong climate science disinformer Roy Spencer and long wrong Scafetta the widget man. You are cherry-picking graphs that fit your theory. Poorly made graphs which one can see directly is not taken from a scientific paper, but instead created by some denier at some anti-science blog.......

Quoting iceagecoming: Nice graphic, iceagecoming. Does it serve any useful purpose beyond being used as blog decor? ;-) I must admit that it does have nice eye appeal. I would give it a 7.5, out of a possible 10 Member Since: 24 août 2010 Posts: 0 Comments: 4139

Quoting greentortuloni: Ah, so that was you with the gerbils! Bastard, those were my only pair of clean shoes. GAH! See how tricksy the Google is? They got me to blow my own cover! "Don't be evil" indeed!! I'm phasing out by gerbils, so if anyone has snakes to feed... Member Since: 30 octobre 2005 Posts: 0 Comments: 1805

Quoting Snowlover123: The problem is that we were actually warming in HadCruT4 in the 1990s, wheras in the 2000s we have flatlined, so an accurate comparison cannot be made. That's simply not true. Look at the Marohosy graph again. I'll tell you what see, shall I? What you see is that the temperature at left end appears to be the same as the the temperature on the right end. That in no way means that there has been no warming. In fact, that graph indicates that the upward trend continues. Just counting the data points we see that eight of the fifteen data points are above the "zero" line; just two are below that line; and three are on that line. Additionally, the two highest highs are further from "zero" than the lows are. Eyeballing graphs to identify a trend is poor practice, of course. However, with this particular graph there is no possible conclusion other than there is an upward trend over the time of measurement. Whether that trend is statistically significant is another matter and unrelated to the assertion you made. Member Since: 30 octobre 2005 Posts: 0 Comments: 1805

Quoting Snowlover123: There are skeptics like me who want clean energy. Not very many, but there are other skeptics like me out there. I agree. It's unfortunate that there aren't more like you. Member Since: 30 octobre 2005 Posts: 0 Comments: 1805

I would give it a 7.5, out of a possible 10 I am curious about the past, this illustrates either Humanoid intervention (we did use fire a millions ybp) or some rather large energy input especially 210-190 ybp for a 6 degree jump up and back down 8. Very likely solar, but I'll be open for any suggestions. Member Since: 27 janvier 2009 Posts: 21 Comments: 853
