Hard freeze likely to significantly damage Midwest fruit trees
Posted by: Dr. Jeff Masters, 13:13 GMT le 26 Mars 2012 +31
After a week of temperatures in the 70s and 80s last week, it was a rude awakening for Michigan this morning, as temperatures across all but the extreme southern portions of the state dropped below freezing. Tonight, far colder temperatures in the low to mid-20s are expected across the entire state, and frosts and freezes are also expected in all of Ohio, plus portions of Indiana, Kentucky, Wisconsin, West Virginia, Virginia, Pennsylvania, Delaware, North Carolina, Maryland, Washington D.C., and New Jersey. A hard freeze (temperatures below 28°F ) will cause widespread damage to flowering plants fooled into blooming by last week's unprecedented "Summer in March" heat wave. Temperatures as hot as 90° hit Michigan last week, and the National Weather Service in Detroit called the "Summer in March" heat wave "perhaps the most anomalous weather event in Michigan since climate records began 130 years ago."


Figure 1. Frost and freeze advisories (white colors) are posted today for all of Lower Michigan and all of Ohio, plus portions of Indiana, Kentucky, Wisconsin, West Virginia, Virginia, Maryland, Pennsylvania, Delaware, North Carolina, Washington D.C., and New Jersey. Although freezing temperatures in the extreme Northeast are also expected, the growing season there has not yet begun, since last week's heat was not long-enough lived in that part of the country.

Fruit trees at risk
Tonight's hard freeze poses a significant danger to the region's fruit industry, and growers of apples, pears, peaches, nectarines, plums, and cherries are gearing up to battle the freezing temperatures by operating large fans and propane heaters in orchards in an attempts to keep temperatures a few degrees warmer. While freezing temperatures for an extended period will not kill the trees, they will destroy the flowers and fragile buds that are needed to produce fruit later in the year. The situation this week is similar to what occurred in 2007. A warm spell in March that year was followed by cold temperatures in early April that were 10 - 20 degrees below average, bringing killing frosts and freezes to the Midwest and South that caused $2.2 billion in agricultural damage, wiping out apple, peach, winter wheat and alfalfa crops. In an interview with citizensvoice.com, Ian Merwin, Ph.D., a horticulturist who specializes in tree fruit at Cornell University in Ithaca, N.Y., said, "I'm pretty sure this will be the earliest bloom, going back at least to the early 1900s. We are definitely in a very risky situation right now for the fruit crop in the whole Northeast."

Correct, Hydrus. How can we be that old when they keep telling us time is passing us by? We should be getting younger, if that is true. ;-) ... That's my story, and I'm stickin' to it! ...

Quoting MAweatherboy1:

So do you believe we can reverse climate change?


I'm a scientist by training and disposition. I try not to "believe" in anything too much but to try to figure out the probabilities, the odds, of outcomes.

There's no way for us to know the future with any certainty. All we can do is to take the facts we have and use them to generate a "best guess".

Can we reverse climate change? I'll answer another question first...

Can we slow climate change? Yes, we have the technology right now that would allow us to cut our fossil fuel use enough to slow climate change significantly.

I think that's 99% likely to be correct.

Can we stop the planet from warming? No, even if we stopped burning fossil fuels today we've already put enough greenhouse gas into the pipes that the planet will continue to warm for some decades.

Again, I'm going to give that a 99% probability.

Have we gone so far that we've triggered events (e.g., permafrost melt) that will take over and significantly warm the planet even if we stop burning fossil fuels?

I don't have enough facts to make a knowledgeable guess. I'm going to have to give that one a 50% probability, a 50:50 chance that we're screwed.

If we haven't passed the point of no return can we reverse climate warming (your question)?

My understanding is that if we stop burning fossil fuels in time and we haven't let things go too far then over a few decades the CO2 and other greenhouse gases will work their way back out of the atmosphere and the climate will return to about where it was before. But it might take a long, long time to regrow polar ice and stuff like that.

If we've passed the point of no return or allow ourselves to pass the point of no return will humans go extinct?

I'm guessing, based on our technological skills and the fact that those kinds of temperatures are likely decades away, that we could protect some "breeding stock". Whether that's a few dozen, hundreds, thousands, or even millions, I have no guess.

I'd give us about a 90% probability of keeping humans from going completely extinct. (Think biosphere or space lab sort of existence, worst case.)

Now, what do I think we should do?

Obviously act as if we can prevent a runaway climate.

To act otherwise would be butt-foolish. If you're out in the ocean and your boat starts to leak then you bail. It might not save you, but it will keep you from drowning sooner and gives you a fighting chance.

Our first job, I think, is to quit making it worse. Do that and we give the people youngest of us a chance to come up with a way to save the world's bacon.

There might be some technology out there that would pull the CO2 and other greenhouse gases out of the atmosphere and we should give the folks who follow us as much time as possible to invent it.

But we should not sit on our rear ends and assume that some smart folks will come up with a solution.

It's time to grab our biggest buckets and bail like a scared man....

Quoting BobWallace:


Jed - people have pointed you toward the facts over and over and over and over.

You seemingly refuse to consider the facts.

You have shown absolutely no efforts to seek the facts as far as I can tell.

You have, in essence, stated that you know more than the scientists who have spent their lives studying the issues and you have accused people with Ph.D.s of being liars.

Now you're spinning off into some tin foil hat fantasy that climate change is a plot for some sinister force to take over control of the planet.

You want to know what you can do? Since you asked - you can spend some serious time reading through the arguments and reading the science behind the answers on this site....

http://www.skepticalscience.com/

Start over on the left side of the page where it says "Most Used Climate Myths". If you click on "View All Arguments" you will get a list of all 173 topics. Click on each and you will get (generally) an introductory page and can choose a more advanced page and then a "here's the science" page.

If you don't want to be viewed as a climate change denier then quit acting like one.

(A climate change denier is someone who says "Climate ain't changing and if it is man didn't cause it and I ain't got no stinkin' data to back up my position". "Furthermore I refuse to look at your data.")

If, in your reading, you find some scientific evidence that you believe shows us that the climate is not warming or that the warming observed is due to factors other than greenhouse gases and soot bring that evidence forward and we'll take a look at it along with you.

Fair enough?




I haven't stated that I don't believe the Climate is warming. Furthermore, I have not stated the humans are not causing Climate Change. Why then do you and some others here treat me as if I do? Additionally, I never accused anyone with a PHD of being a liar, I was making a point that just because someone has a PHD doesn't mean we accept everything they say, I'm urging people to, you know, think for themselves. I don't have any proof any scientist right now is a liar and I don't plan on calling any scientist a liar unless I know for sure because otherwise it would be slander.


I stated once before I have not sought to gain proof of some other theory about GW. I don't because I do believe Climate Change is real and Humans adding CO2 into the atmosphere is causing changes and we should move towards ending it.


There is more than one kind of skepticism, so please don't put me into a box. I am skeptical of the science being stretched. For example, earlier in the blog I objected to where science is stretched to what appears to be inciting fear and agenda as I examined earlier in an article. The article clearly made a stretch of truth to put it nicely, by claiming in the near future Climate Change could be irreversible which is just not true. I have no way of knowing this article is written in direct attempt to scare people, I hope that isn't the case, but if its not, its still stretching the real science involved which is just that even if we change things now there will be delayed effects of Climate Change that will continue many years after.

At least is not bone dry right now as it was a few weeks ago in all of West Africa as moisture tries to increase a little bit. Maybe the big drought that has affected that part of the world for the past few months is losing some of it's punch. We will see if that is correct as the days and weeks go by.

You seem to be quite certain. Why? By your reasoning, we will just keep polluting, never even use technology (which is what allows you to be on WU), and just go the way of the dinosaurs.
For concerted human action there needs to be a certain level of shared pain. However the action is always to relieve the pain not to reverse the cause, in this case part of the cause is our over-reliance on technology.

I haven't really done research on which ENSO phase favors more activity in Florida. However, I would imagine that neutral years do.
