Warmest 12-Month Period Recorded In US 297

First time accepted submitter seanzig writes "Dr. Jeff Masters of Weather Underground provides a good overview of the State of the Climate Report from NOAA's National Climatic Data Center (NCDC). May 2011 through Apr. 2012 broke the previous record (Nov. 1999 — Oct. 2000). A number of other interesting records (e.g., warmest March on record) and stats emerged. It just presents the data and does not surmise anything about the causes or what should be done about it."

      They have repeatedly claimed that snow implies that Global Warming is a hoax.

      This is why I don't like the arguers against AGW, they resort to such cheap shots that it's hard to take them seriously. It definitely works on their target demographic though.

      Note: I am in no way implying that a hot summer is evidence of global warming.

        I am personally rather indifferent to the whole GW/AGW affair. That said, it's just silly to infer that extra snow means the globe isn't warming. For example, consider: if 100 billion tons of ice melts at the poles, and global snow levels then increase, in winter, when was the water cooler: 1) when it spent all year round being ice, or 2) when it spends 4 months a year as ice? If you guessed #1, you'd be right.

        Of course, I can ask the question a different way, and just make you mental. If the globe is warming, and the average temperature goes up, would it be possible for the increased water vapor as it traveled across the poles to actually generate an expanding ice sheet? If you agreed that it was possible, you'd be right.

        Now the part that will make you mental is that these two questions imply answers that could be superficially viewed as contradictory. I'm fun at a party, eh?

          Indeed. In the process of joining conclusions backwards to supporting evidence, may denialists indeed use such an argument. The smart ones move onto smarter arguments, but nothing that hasn't already been definitively answered for someone willing to look.

          Political reasoning is abhorrently dishonest, even in really smart people. Curiously enough, the mind prevents us from seeing just how dishonest we are being with ourselves. We really could solve our problems with politics didn't involve so much head-in-ass time.

            Political reasoning is abhorrently dishonest, even in really smart people. Curiously enough, the mind prevents us from seeing just how dishonest we are being with ourselves.

            In my mind it's all about confirmation bias. Which is to say, when confronted with a larger list of facts to assess, human beings have a remarkable ability to select only a small subset of the facts and use those to confirm their beliefs. I encountered this last year. I will relay the anecdote.

            Sometime last year a study came out that "proved" that caffeine drinkers who regularly drink caffeine induce no practical effect to themselves, and only restore themselves to what would be a baseline level. Over a twenty year period I have read summaries on many, many caffeine studies. This particular study stood alone as an outlier in a much larger field of study. I noted this with amusement and went on with my life.

            One day not so long later, I was getting coffee at work. A coworker of mine intruded to attempt to tell me about the study. I cut him off cold, and was quite irritated. This coworker was Mormon. I did not need to mire in the narrowly minded comfort-confirmed mentality of someone who is able to learn nothing else. It's just sad, really.

            Of course on the subject of global warming, the issue is political. I once heard a great definition of politics, once: "politics is who gets what". It's true. While politics is about many things, it's certainly about resource allocation, and when you consider it from that perspective, and decide to tolerate the notion that for human beings resource allocation will always be highly contentious, what you will do is become a bit jaded like me, which is to say, unsurprised, disdainful, and accepting of the ugliness of politics all at the same time.

        What are you talking about? 500 ppm is pretty much inevitable at this point. IPCC predictions go as high as 900ppm in 2090 and even the IPCC doesn't predict the end of civilization at that level. In fact, even in the absolute worst case scenario, namely total melting of all ice caps over a few centuries (and that's how long it's going to take no matter what), how do you imagine that would end civilization?

      "Well, I think there's little disagreement that a "large" fraction is human caused, although obviously some small fraction is natural variation."

      I don't know whether this is disingenuous or you just don't understand.

      The whole reason there even exists controversy about this in the first place, is that the signal is very small in relation to the noise: any human-caused differences are so small in relation to the natural variations that it has been nearly impossible to detect (if, indeed, it has actually been detected).

      "some small fraction is natural..." is not the real situation at all. The problem is the opposite: the vast majority of it is natural. Any scientist, even the staunchest AGW supporter, will admit that if he/she has any pretension to honesty at all.

      • "the signal is very small in relation to the noise"

        That's a nice, concise explanation. While that seems to be intuitive for many, it's never made sense to me. I find human-generated noise often deafening.

        Billions of people extracting carbon from the bowels of the earth and shooting it by the ton into the sky, year after year, decade after decade, seems more or less competitive with, say, a volcanic eruption here and there.

      Sure, and it is a valid point when one has a few weeks of cold or even a few months of cold. And by the same token, a year like this one by itself isn't that useful data. It is when data like this year is part of a larger pattern that it becomes a problem. In this context one has a very hot year by a variety of different metrics and that's on top of a gradual increase in average temperature over the last twenty years. Weather and climate are different, but lots of weather change over the long-term is eventually a sign of climate change.

    Reports like this are like a tin can on a fence for anti global warming people. At the time I write this, I see dozens of posts saying "and now all the global warming people will take this as proof", and not one global warming person taking it as proof.

    For the record, this is not proof of global warming. It is a very extreme regional climate event of the type that climate change theory predicts will become common, but you can't attribute individual events to the long-term trend.

    For the record, this means jack diddly in terms of global temperature change, the contiguous US is too small to matter. The past 3 months did not set a global record. However, it has been pretty warm: global temperature this year so far is in the top 25%... just like every other year this century.

    We've had unusually warm or record warm years for 12 to 15 years. There's evidence of it going back to the early 80s. So far it's following the predicted pattern, there's that nasty science, including the southwest being more mild. A shift in the jet stream was supposed to keep Arizona and Southern California mild compared to the rest of the country. Arizona has had a mild winter and now we are well into May with no 100 degree days. Some would call this proof global warming or climate change is false but it's due to the fact they haven't read what the models predicted. I've heard ridiculous claims that it was supposed to be 10 degrees warmer by now so it's false. I never read a single model that predicted that. The worst scenarios are for a roughly 10 degree increase in some areas in a hundred years, not ten. Three to five was the most likely outcome but we are actually running on the high side of all the models so it's likely to be worse than the best case scenario. Look at the statistics. If some one rolled ten or twelve sixes in a row with dice and could predict 90% of his rolls would that be proof of psychic powers? I think even James Randi would accept that as proof. We're seeing the same consistency in weather model predictions. People have claimed the lack of killer hurricanes as proof that it's all a lie while ignoring the explosion in deadly tornadoes. Also tornadoes are happening earlier and later in the year and they are happening from Maine to Southern California. Two places where they are very rare. Other factors can moderate hurricanes but tornadoes are cause by the mixing of warm and cool air. You have the right conditions you tend to get tornadoes. Usually there's only a portion of the country where conditions are right but now they can happen almost anywhere.

    It was a very pleasant year. A gentle winter. Years like this come around time to time. So do nasty winters like the three where we had temperatures of under -25ÂF for weeks on end. Then there was the year where it snowed here every month, including June, July and August. Nasty. These things happen. According to recorded history they've been happening for millennia. According to studies of other things these warming and cooling cycles have been happening for hundreds of millions of years. In fact, traditionally, the Earth has been warmer than it is now. In fact, live and diversity flourished during the warming periods. People are upset because things are changing and they don't like change. Life is change. Change is life.

    I think we are in the interesting part of Climate change right now. Energy levels (not temperature) have increased dramatically in a rather short time and the climate is trying to find a place for all that extra energy now. So the oceans are cycling rapidly (Nina/Nino phases), precipitation levels etc are changing. In essence we're cycling rapidly between extremes. Anecdotally in Utah, last year we had the largest snows on record, and this year is probably the driest on record. For my entire childhood (I'm nearly 40) these cycles were nearly a decade long now they are a cycling in a year.

    This will probably continue for a decade or three as the system tries to stabilize the energy levels and sink some of the temperature increase into the oceans, etc. The models aren't perfect and the deniers point to that, but the reality is we simply don't know how the climate will stabilize these energy levels, we can only make predictions based on previous climates we have rudimentary knowledge of. I'll likely be dead long before the worst of climate change hits (major shifts in breadbasket areas), but I know I'm going to live during the most erratic climate change this world's ever seen.

    The scariest part to me is how to plan for the future because there is one thing the models do predict and that's the bad weather (the kind that kills people) is going to increase dramatically. I was hoping the SW would get wetter as the models predict but it appears, at least during my lifetime, things are just going to get more erratic making it very difficult to predict and manage scarce water resources.

    The funniest part about Climate Change and the Deniers is that the government is planning for it. The military and defense planners and many others are planning for summers where the Arctic passage that's never existed becomes a reality. And before people say this is because of Obama I'll point out this planning started under GW Bush. Those in the know and with power and influence are causing our government to react like Climate change is not only a reality but something that's very important strategically including how to get to all that oil that's in the arctic that no one ever thought would be accessible. This includes a certain pair of brothers that are highly invested in carbon based energy and fund much if not all of the deniers making plans to drill and tap that oil when the ice melts permanently.

    It's sad but I don't think the US will change course on climate change until it's far to late to matter. I'd like to see the construction of 1000 nuclear reactors in the US and a shutdown of most of the coal power plants along with increased gas prices that drive the adoption of electric vehicles. The gas will likely happen on it's own anyway but coal won't stop without outside forces because the US has so much of it.
