The most powerful low pressure system in 140 years of record keeping swept through the Southwest U.S. yesterday, bringing deadly flooding, tornadoes, hail, hurricane force winds, and blizzard conditions. We expect to get powerful winter storms affecting the Southwest U.S. during strong El Niño events, but yesterday's storm was truly epic in its size and intensity. The storm set all-time low pressure records over roughly 10 - 15% of the U.S.--over southern Oregon, and most of California, Nevada, Arizona, and Utah. Old records were broken by a wide margin in many locations, most notably in Los Angeles, where the old record of 29.25" set January 17, 1988, was shattered by .18" (6 mb). Bakersfield broke its record by .30" (10 mb). The record-setting low spawned an extremely intense cold front that rumbled thought the Southwest, and winds ahead of the cold front reached sustained speeds of hurricane force--74 mph--last night at Apache Junction, 40 miles east of Phoenix. Wind gusts as high as 94 mph were recorded in Ajo, Arizona, and a Personal Weather Station in Summerhaven (on top of Mt. Lemmon next to Tucson) recorded sustained winds of 67 mph, gusting to 86 mph, before the power failed. Prescott recorded sustained winds at 52 mph, gusting to 67 as the cold front passed, and high winds plunged visibility to zero in blowing dust on I-10 connecting Phoenix and Tucson. The storm spawned one possible tornado in Arizona, which touched down at 8:32 pm MST in Phoenix near Desert Ridge Mall. No damage or injuries were reported. If verified, it would be only the 7th January tornado in Arizona since record keeping began in 1950.

Three tornadoes in California
Three tornadoes were reported in California yesterday. A small EF0 twister hit the east side of Ventura, leaving a 1.5 mile damage path. Another tornado hit Santa Barbara, downing trees and power poles. The most damaging California tornado yesterday touched down just west of Blythe, on the Arizona-California border, at 4:31 pm MST. The twister crossed I-10, blowing three semi trucks over, ripping the roofs off houses, and downing power lines. I-10 was closed for several hours to clear the debris and toppled trucks.
Two tornadoes also hit Southern California on Tuesday. A sheriff's deputy spotted a possible tornado in Goleta that caused some roof damage, and another tornado hit Huntington Beach, damaging boats and buildings and flipping cars.
If all five tornadoes are confirmed as genuine by the National Weather Service, it will tie the record of most January California tornadoes. The all-time record for most California tornadoes in a single day is seven, set on April 1, 1996, and November 9, 1982.

Figure 3. Storm-relative radial velocity from the Los Angeles Doppler radar at the time of the Santa Barbara tornado. The area of yellow and orange colors, lying right next to a region of blues and greens just west of Santa Barbara shows that the winds in that region were moving towards and away from the radar in a very tight area, signifying the presence of a rotating thunderstorm and possible tornado.
The storm will continue to bring heavy rain and snow to many portions the Southwest today, then wind down on Saturday. A new storm is expected to move ashore over Northern California on Sunday night, but this storm will not be as intense. Another storm is also possible next Friday, January 29, but it appears that a renewed battering by a long succession of storms like we had this week will not occur next week.

Tornadoes, severe weather in the South
Severe weather associated with a separate storm brought damaging winds, hail, and tornadoes to portions of Kentucky, Tennessee, Georgia, Alabama, and Florida last night. Two tornadoes were reported, one in Tennessee, and one in Alabama, near Huntsville. The Huntsville tornado injured approximately six people, and cut power to 10,000 people. The storm responsible for the severe weather has moved out to sea, and no further severe weather is expected today. A slight chance of severe weather is expected Saturday over Arkansas and Mississippi, and there is also a severe weather threat for Georgia and surrounding states on Sunday.

Figure 4. Last night's Huntsville, Alabama tornado was captured by wunderphotographer Southampton.
Portlight's Paul Timmons to appear on NBC and CNN
Portlight.org, the disaster-relief charity that has sprung up from the hard work and dedication of many members of the wunderground.com community, has successfully shipped medical equipment and a water filtration unit capable of supplying the needs of 3,500 people per day to the Dominican Republic. The relief supplies were trucked to Haiti via road, and have made it to the earthquake zone. The supplies have been targeted to go to those with disabilities, or to those who are living in areas where the main aid efforts have been inadequate. Portlight is working through the local Catholic Church, which is probably best positioned to deliver private aid donations to those in need. Paul Timmons, leader of the Portlight relief efforts, is scheduled to appear on NBC news later today, and on CNN news tomorrow, to discuss Portlight's efforts.

Figure 5. Walkers and medical supplies for Haiti getting ready to ship from the Portlight warehouse in Atlanta.
Please visit the Portlight.org blog to learn more. Floodman's blog has the latest info on Portlight's plan for Haitian relief. The Reeve Foundation, founded by Christopher and Dana Reeve has awarded Portlight Strategies a $10,000 Quality of of Life grant to assist in the relief efforts in Haiti. This is very big and will allow Portlight to pursue more aggressive relief efforts over the course of the next few weeks.
For those of you more interested in helping out with the long-term rebuilding of Haiti's shattered infrastructure from the quake, I recommend a contribution to Lambi Fund of Haiti, a charity that is very active in promoting reforestation efforts, use of alternative fuels, and infrastructure improvements at a grass-roots level in Haiti. I've developed a great respect for the work they do in the country in the five years I've been a supporter.

TOP PRIORITY
TROPICAL CYCLONE ADVICE NUMBER 5
Issued by the Bureau of Meteorology, Brisbane
Issued at 10:59pm EST on Saturday the 23rd of January 2010
A Cyclone WARNING is now current for coastal and island areas from Cape Melville
to Cardwell.
The Cyclone WATCH from Coen to Cape Melville and Cardwell to Lucinda has been
CANCELLED.
At 10:00 pm EST Tropical Cyclone Olga, Category 2 was estimated to be
250 kilometres east northeast of Cairns and 365 kilometres north northeast of
Townsville, and was moving west at 21 kilometres per hour.
GALES are expected to develop about the coast between Cape Melville and Cardwell
on Sunday.
DESTRUCTIVE WINDS are likely to develop about the coast between Cape Tribulation
and Innisfail on Sunday afternoon as the cyclone centre approaches.
Very heavy rainfall with localised flooding is expected to develop about the
North Tropical Coast during Sunday.
As the cyclone crosses the coast, abnormally high tides are expected between
Cape Tribulation and Innisfail, but the sea level should not exceed the highest
tide of the year. Large waves are likely along the beachfront.
People between Cape Melville and Cardwell should immediately commence or
continue preparations, especially securing boats and property.
Details of Tropical Cyclone Olga at 10:00 pm EST:
.Centre located near...... 16.2 degrees South 148.0 degrees East
.Location accuracy........ within 35 kilometres

The deaths in the use of generators are due to Carbon Monoxide (CO). It is structurally different than Carbon Dioxide (C02) in the fact that it forms when there is not enough oxygen in the air to produce Carbon Dioxide. It is far more lethal than (C02), due to the fact that it latches on to hemoglobin in the blood (250X more efficiently than oxygen) and denies the transport of oxygen to body tissues.
In other words..the facts presented could care less what One Individual or a Body of Political thought believes.
Thats how science works.
Some spout off as if their the inquisition..
and the science is Da Vinci.
The agreed scientific position is and remains the facts.
Carbon dioxide content in fresh air (averaged between sea-level and 10 hPa level, i.e. about 30 km altitude) varies between 0.036% (360 ppm) and 0.039% (390 ppm), depending on the location[43].
Prolonged exposure to moderate[clarification needed] concentrations can cause acidosis and adverse effects on calcium phosphorus metabolism resulting in increased calcium deposits in soft tissue. Carbon dioxide is toxic to the heart and causes diminished contractile force.[42]
Toxicity and its effects increase with the concentration of CO2, here given in volume percent of CO2 in the air:
* 1%, as can occur in a crowded auditorium with poor ventilation, can cause drowsiness with prolonged exposure.[2]
* At 2% it is mildly narcotic and causes increased blood pressure and pulse rate, and causes reduced hearing.[42]
* At about 5% it causes stimulation of the respiratory centre, dizziness, confusion and difficulty in breathing accompanied by headache and shortness of breath.[42]. In addition at this concentration panic attacks may occur.[44][45]
* At about 8% it causes headache, sweating, dim vision, tremor and loss of consciousness after exposure for between five and ten minutes.[42]
A natural disaster linked to CO2 intoxication occurred during the limnic eruptions in the CO2-rich lakes of Monoun and Nyos in the Okun range of North-West Cameroon: the gas was brutally expelled from the mountain lakes and leaked into the surrounding valleys, killing most animal forms. During the Lake Nyos tragedy of 1988, 1700 villagers and 3500 livestock died.
http://en.wikipedia.org/wiki/Carbon_dioxide#Toxicity
How does carbon--dioxide from generator kills?
The main problem is that if you are inhaling carbon dioxide instead of normal air, then you are obviously breathing reduced oxygen or no even no oxygen at all. Any gas can kill by this means, simply because you're breathing it instead of getting oxygen. A second problem is that carbon dioxide becomes an acid when it dissolves in water. Blood is mostly water, so breathing carbon dioxide will make your blood acidic and that can disrupt your body chemistry.
I don't know what kind of engine you're talking about, but normal generator emissions are made up of mostly Nitrogenous gas (N2), Carbon Dioxide (CO2) and Water Vapor (H20). Engines are also made to reduce the emissions of: CO, VCOs, and Nitrogen Oxides. Therefore, it depends on your own engine emissions rates but generally, cases of CO2 poisoning is very rare and is often caused in conjunction with other gases. Here's an example: CO2 is usually at 380 part per million (ppm) in the air you and I breath in. But at 1% or 10,000 ppm (26 times the normal concentration) you would feel drowsy and according to British Medical Journals it takes about 10-25% CO2 (100,000-250,000 ppm, roughly 260 - 650 times normal amounts of CO2 concentrations in the air) to kill. Now, Carbon Monoxide (CO) only takes 35 ppm (0.0035%) to cause headache and dizziness after long periods of exposure (~8 hours). Exposure at 3,200 ppm can cause death within 30 minutes and at ~13,000 ppm causes death in 2-3 breaths and in less than 3 minutes. So to summarize - Carbon dioxide CAN kill, but you'll most likely get killed due to Carbon monoxide poisioning many times over already, and kills in roughly the same way as CO2.

Nevertheless Co-2 is still toxic.
The map shows temperature changes for the last decade—January 2000 to December 2009—relative to the 1951-1980 mean. Warmer areas are in red, cooler areas in blue. The largest temperature increases occurred in the Arctic and a portion of Antarctica. Credit: NASA
2009: Second Warmest Year on Record; End of Warmest Decade
2009 was tied for the second warmest year in the modern record, a new NASA analysis of global surface temperature shows. The analysis, conducted by the Goddard Institute for Space Studies (GISS) in New York City, also shows that in the Southern Hemisphere, 2009 was the warmest year since modern records began in 1880.
Although 2008 was the coolest year of the decade -- due to strong cooling of the tropical Pacific Ocean -- 2009 saw a return to near-record global temperatures. The past year was only a fraction of a degree cooler than 2005, the warmest year on record, and tied with a cluster of other years -- 1998, 2002, 2003, 2006 and 2007 -- as the second warmest year since recordkeeping began.
“There’s always an interest in the annual temperature numbers and on a given year’s ranking, but usually that misses the point,” said James Hansen, the director of GISS. “There's substantial year-to-year variability of global temperature caused by the tropical El Niño-La Niña cycle. But when we average temperature over five or ten years to minimize that variability, we find that global warming is continuing unabated."
January 2000 to December 2009 was the warmest decade on record. Throughout the last three decades, the GISS surface temperature record shows an upward trend of about 0.2°C (0.36°F) per decade. Since 1880, the year that modern scientific instrumentation became available to monitor temperatures precisely, a clear warming trend is present, though there was a leveling off between the 1940s and 1970s.
The near-record temperatures of 2009 occurred despite an unseasonably cool December in much of North America. High air pressures in the Arctic decreased the east-west flow of the jet stream, while also increasing its tendency to blow from north to south and draw cold air southward from the Arctic. This resulted in an unusual effect that caused frigid air from the Arctic to rush into North America and warmer mid-latitude air to shift toward the north.
"Of course, the contiguous 48 states cover only 1.5 percent of the world area, so the U.S. temperature does not affect the global temperature much,' said Hansen.
In total, average global temperatures have increased by about 0.8°C (1.4°F) since 1880.
“That’s the important number to keep in mind,” said Gavin Schmidt, another GISS climatologist. “In contrast, the difference between, say, the second and sixth warmest years is trivial since the known uncertainty -- or noise -- in the temperature measurement is larger than some of the differences between the warmest years."
Decoding the Temperature Record
Climate scientists agree that rising levels of carbon dioxide and other greenhouse gases trap incoming heat near the surface of the Earth and are the key factors causing the rise in temperatures since 1880, but these gases are not the only factors that can impact global temperatures.
Three others key factors -- including changes in the sun’s irradiance, oscillations of sea surface temperature in the tropics, and changes in aerosol levels -- can also cause slight increases or decreases in the planet's temperature. Overall, the evidence suggests that these effects are not enough to account for the global warming observed since 1880.
Without CO2 removal via this method,..one would perish within Hours aboard any of these Human transport vehicles.
It one dosent realize that,well..then they need not expound on anything else via the scientific method here.
Portlight helps..

New Orleans Saints Superdome screaming lessons from an opera singer.
Our atmosphere is unique in the solar system. At sea level it has a pressure of about 1 x 105 pascals (Pa). The total mass is 5.3 x 1018 km which is about 1 millionth of the total mass of the planet (5.97 x 1024 kg). The atmospheric structure is stratified by gravity and characterized by the complex photochemical interactions between sunlight and the various molecular species present.
Typical composition of dry air at sea level:
Species Percent by Volume
N2 78.08
O2 20.95
Ar 0.93
CO2 0.031
Ne 0.0018
He 0.00052
Kr 0.00011
Xe 0.0000087
H2 0.00005
CH4 0.0002
NO 0.00005
O3 0.000007 (summer)
0.000002 (winter)
Note that only nitrogen, oxygen and argon are present in any appreciable amounts. Water vapor varies from nearly zero up to about 4% (100% humidity at 120°F, 1 atm) and averages about 0.8%.
Composition of the atmosphere varies little from this with altitude except ozone, water vapor, and carbon dioxide. Water vapor is almost totally absent above about 8 km
(a CO level of 400 ppm and higher) will result in unconsciousness
- Carbon Dioxide (CO2) levels in the atmosphere have risen from 0.028% to 0.038% (380ppm) over the past 100 years (IPCC)
- Carbon Dioxide (CO2) is not toxic until 5% (50,000ppm) concentration (Source)
CO2 is hazardous via direct toxicity at levels above 5%, concentrations not encountered in nature outside of volcanic settings and water-logged soils

So the scientific answer is the CO kills from the generator kills you 137 times faster.(Irreversible CO poisoning versus reversible CO2
poisoning)
Science and philosphy both thrive from logic and
wisdom: The Warmists should learn from the past:
It cannot be when the root is neglected that what springs from it will be well ordered.
CONFUCIUS, The Wisdom of Confucius
LOL!
And he posts something with CO2 at up to 8%!
Yet, CO is the one that actually gets into your blood and takes the place of O2 and is the one that kills...I see he might have learned something new. But, my post is still unsubstantiated and charlottefl doesn't know what he is talking about.
CO2 in the concentrations found in the atmosphere is not a danger to human health and will never be according to the scariest projections.
Someone let me know when this guy is old enough to understand something besides the fear-media and the wiki-warming-section and I'll take him off the *poof* list.
.."Just do your best,in everything you do"...
Due to the health risks associated with carbon dioxide exposure, the U.S. Occupational Safety and Health Administration says that average exposure for healthy adults during an eight-hour work day should not exceed 5,000 ppm (0.5%). The maximum safe level for infants, children, the elderly and individuals with cardio-pulmonary health issues is significantly less. For short-term (under ten minutes) exposure, the U.S. National Institute for Occupational Safety and Health (NIOSH) and American Conference of Government Industrial Hygienists (ACGIH) limit is 30,000 ppm (3%). NIOSH also states that carbon dioxide concentrations exceeding 4% are immediately dangerous to life and health[46] although physiological experiments show that such levels can be tolerated for some time [47].
Adaptation to increased levels of CO2 occurs in humans. Continuous inhalation of CO2 can be tolerated at three percent inspired concentrations for at least one month and four percent inspired concentrations for over a week. It was suggested that 2.0 percent inspired concentrations could be used for closed air spaces (e.g. a submarine) since the adaptation is physiological and reversible. Decrement in performance or in normal physical activity does not happen at this level.[47][48] However, it should be noted that submarines have carbon dioxide scrubbers which reduce a significant amount of the CO2 present.[49]
These figures are valid for pure carbon dioxide. In indoor spaces occupied by people the carbon dioxide concentration will reach higher levels than in pure outdoor air. Concentrations higher than 1,000 ppm will cause discomfort in more than 20% of occupants, and the discomfort will increase with increasing CO2 concentration. The discomfort will be caused by various gases coming from human respiration and perspiration, and not by CO2 itself. At 2,000 ppm the majority of occupants will feel a significant degree of discomfort, and many will develop nausea and headaches. The CO2 concentration between 300 and 2,500 ppm is used as an indicator of indoor air quality.
Acute carbon dioxide toxicity is sometimes known by the names given to it by miners: blackdamp (also called choke damp or stythe). Backdamp is primarily nitrogen and carbon dioxide and kills via suffocation (having displaced oxygen). Miners would try to alert themselves to dangerous levels of blackdamp and other gasses in a mine shaft by bringing a caged canary with them as they worked. The canary is more sensitive to environmental gasses than humans and as it became unconscious would stop singing and fall off its perch. The Davey lamp could also detect high levels of blackdamp (which collect near the floor) by burning less brightly, while methane, another suffocating gas and explosion risk would make the lamp burn more brightly).
Carbon dioxide ppm levels (CDPL) are a surrogate for measuring indoor pollutants that may cause occupants to grow drowsy, get headaches, or function at lower activity levels. To eliminate most indoor air quality complaints, total indoor CDPL must be reduced to below 600. NIOSH considers that indoor air concentrations that exceed 1,000 are a marker suggesting inadequate ventilation. ASHRAE recommends they not exceed 1,000 inside a space.

Get Krunk Who Dats,for the Promised land is nye...
Farve on da turf,looking like a Smurf..
I dont believe no one intended to say the atmosphere is going to become toxic to Humans.
That isnt a sensible deduction,.it may be a good skewed re-tort for some maybe,..
But the Co2 increase is the driver of the warming,no debate there..and all the latest Modeling suggest its going to warm at a faster rate which will affect the Globe in a increasingly detrimental fashion..and the Humans scurrying about it.
And once again,..if one denies the pollutants cause and effect,where do all the toxicity go when pumped into the atmosphere 24/7/365..?
Sarasota?
Ones thought process,or "belief" dosent drive the conclusions or the science process involved in the findings,..the data does.
Now if we talk about co-2 concentrations in the atmosphere, there Co2 acts as a potent greenhouse gas. As 380ppm seem not much in regards to direct health concern, the greenhouse effect will trigger more warming from positive feedbacks, stronger storms, climate out of balance. The last 15 million years we had around 280ppm. and since the industrial revolution the fossil energy stored beneath the earth gets released into the atmosphere - fueling the energy of the climate system.
This is in fact the biggest experiment of humankind - all the planet life forms related. Than there is the speed of the emission released into the atmosphere, which is the fastest in earth history.

Canada
2009 Australia had it's 2nd hottest year on record
But as some will say,..a Local specific region dosent drive home a warming debate,..
But I can say this..Down Under has been a tad warm the past two Summers,and I dont think anyone would disagree there.
Science: CO2 levels haven’t been this high for 15 million years, when it was 5° to 10°F warmer and seas were 75 to 120 feet higher — “We have shown that this dramatic rise in sea level is associated with an increase in CO2 levels of about 100 ppm.”

You would have to go back at least 15 million years to find carbon dioxide levels on Earth as high as they are today, a UCLA scientist and colleagues report Oct. 8 in the online edition of the journal Science.
“The last time carbon dioxide levels were apparently as high as they are today — and were sustained at those levels — global temperatures were 5 to 10 degrees Fahrenheit higher than they are today, the sea level was approximately 75 to 120 feet higher than today, there was no permanent sea ice cap in the Arctic and very little ice on Antarctica and Greenland,” said the paper’s lead author, Aradhna Tripati, a UCLA assistant professor in the department of Earth and space sciences and the department of atmospheric and oceanic sciences.
“Carbon dioxide is a potent greenhouse gas, and geological observations that we now have for the last 20 million years lend strong support to the idea that carbon dioxide is an important agent for driving climate change throughout Earth’s history,” she said.
Yes, pumping more and more CO2 into the air is a very bad idea, as this news release from UCLA on a major new study makes clear. The study itself, “Coupling of CO2 and Ice Sheet Stability Over Major Climate Transitions of the Last 20 Million Years,” (subs. req’d) was released by Science earlier this month.
The study notes importantly, “This work may support a relatively high climate sensitivity to pCO2” [the partial pressure of CO2], which is the same conclusion that a number of major studies looking at paleoclimate data have come to:
Scientists analyzed data from a major expedition to retrieve deep marine sediments beneath the Arctic to understand the Paleocene Eocene thermal maximum, a brief period some 55 million years ago of “widespread, extreme climatic warming that was associated with massive atmospheric greenhouse gas input.” This 2006 study, published in Nature (subs. req’d), found Artic temperatures almost beyond imagination–above 23°C (74°F)–temperatures more than 18°F warmer than current climate models had predicted when applied to this period. The three dozen authors conclude that existing climate models are missing crucial feedbacks that can significantly amplify polar warming.
A second study, published in Geophysical Research Letters (subs. req’d), looked at temperature and atmospheric changes during the Middle Ages. This 2006 study found that the effect of amplifying feedbacks in the climate system–where global warming boosts atmospheric CO2 levels–”will promote warming by an extra 15 percent to 78 percent on a century-scale” compared to typical estimates by the U.N.’s Intergovernmental Panel on Climate Change. The study notes these results may even be “conservative” because they ignore other greenhouse gases such as methane, whose levels will likely be boosted as temperatures warm.
The third study, published in Geophysical Research Letters (subs. req’d), looked at temperature and atmospheric changes during the past 400,000 years. This study found evidence for significant increases in both CO2 and methane (CH4) levels as temperatures rise. The conclusion: If our current climate models correctly accounted for such “missing feedbacks,” then “we would be predicting a significantly greater increase in global warming than is currently forecast over the next century and beyond”–as much as 1.5°C warmer this century alone.
So we need to keep atmospheric concentrations of CO2 as low as possible — and if we do go above 450 ppm, we need to get back to under 350 ppm as rapidly as possible, preferably by century’s end, though that would be no easy feat.

“A slightly shocking finding,” Tripati said, “is that the only time in the last 20 million years that we find evidence for carbon dioxide levels similar to the modern level of 387 parts per million was 15 to 20 million years ago, when the planet was dramatically different.”
Levels of carbon dioxide have varied only between 180 and 300 parts per million over the last 800,000 years — until recent decades, said Tripati, who is also a member of UCLA’s Institute of Geophysics and Planetary Physics. It has been known that modern-day levels of carbon dioxide are unprecedented over the last 800,000 years, but the finding that modern levels have not been reached in the last 15 million years is new.
Prior to the Industrial Revolution of the late 19th and early 20th centuries, the carbon dioxide level was about 280 parts per million, Tripati said. That figure had changed very little over the previous 1,000 years. But since the Industrial Revolution, the carbon dioxide level has been rising and is likely to soar unless action is taken to reverse the trend, Tripati said.
“During the Middle Miocene (the time period approximately 14 to 20 million years ago), carbon dioxide levels were sustained at about 400 parts per million, which is about where we are today,” Tripati said. “Globally, temperatures were 5 to 10 degrees Fahrenheit warmer, a huge amount.”
This summer has been warmer than any summer i have experienced. 108.1F here on Saturday till 15:30 then the front came through and the temp went down to 71F

NWS in Melbourne has got their tornado & storm damage report together. I'll post the path but their report is worth a visit..great radar saves, lots of damage photos, even road cam with a trailer on it's side. Too close to Brevard Zoo..
Favorite buoy report..
