Snowball in Hell

The forecast low in Central Park today is expected to match its previous record high from Christmas Eve of 1996 of 63°F / 17°C. By the afternoon, temperatures should reach the low 70s (22°C), shattering the record by 10 degrees F.

With some help from an El Niño, 2015 is expected to be the warmest year ever recorded. November was very nearly a full 1°C above 20th century averages; January through November was 0.25C warmer than the same period last year. Some of the most remarkable warming last month was far away from the Pacific, however: in the Arctic temperatures are 4 to 10 degrees C (7 to 18 degrees Fahrenheit) above normal.

The press are just biding their time for when we get a cold snap in the new year, and the headlines will be paraphrases of 'WHERE'S YOUR STUPID WARMING NOW, EH? EH?' (see Drinky Die's link).

For no good reason I booked a mid-January east coast vacation. After I did that I looked at weather records for 2014. It was damn cold in 2014. I went out and bought lots of merino wool and polartec. Now, it looks like it'll be cold but not damn cold. Global warming doesn't seem to mean that any place gets uniformly warmer. Global warming seems to mean that the average temperature rises a bit and the variability spikes.

Sigh. The signature of climate change is not warmer temperatures in a given region in a given continent, it is more variance from the historic mean.

Pointing at a warmer winter in [this place][this year] as evidence (which should not be fucking necessary at this point, but most people are idiots, sure, OK) is counterproductive, because the increase of boundary-violating energy in the climactic system could mean (El Nino notwithstanding) that it might well be stupid cold there next time 'round, which would give fuel to the deniers.

I agree with STWChicken.. Ironic how, when the deniers point to a bit of a cold spell we tell them that Climate Change can't be disputed by a bit of cold air, but when we get a warm spell we do the exact same thing...

That said, I'm sitting in my chair a mile away from center of Hell, and the temperature in Hell was 60 degrees yesterday. (and, there's not a snowball to be found, the title of this FPP is a bit misleading!)

It's forecasted to be 70 degrees here in southern New Hampshire today.

I feel quite comfortable referring to this and exceptionally cold winters, as evidence of climate change. Not global warming, but climate change. The climatic extremes are more extreme and swinging more broadly. Storms are occurring more intensely and out of season. Things are changing at a rate wildlife and plants can't cope with our respond to from year to year - or do you think it's normal and unconcerning for the crocus bulbs to be pushing out of the New Hampshire soil in December?

It's good to recognize that this is an El niño year, and that that exacerbates and changes weather patterns. It's also good to be cognizant of weather patterns in context globally and over a few years. This year is aberrantly warm because of El Niño, but you can't blame the past several years of aberrant warmth and strong storms and drought and polar vortices and wildfires on that. The earth's climate is changing, and this year, those changes were intensified.

Caution. It is vitally important not to make connections.

My kids were playing basketball outside yesterday. That's not normal Nova Scotia activity for late December. We often have mild starts to winter, and being on the ocean saves us from the really deep freezes, but double-digits Celcius is just wrong.

It's not that it's warmer than usual. For at least a decade our weather has been stranger than normal, very different from decades past.

Checking in from Kingston, Ontario and yeah, it's definitely warmer this Christmas Eve than last year's. It's not even 9 am and we're sitting at 52F. I personally don't mind a green Christmas as it reminds me of pretty much every Christmas I had as a kid in the South, but my Canadian husband is having kittens about it.
posted by Kitteh at 5:24 AM on December 24, 2015


It's in the 20s here and supposed to be in the single digits within a few days, but the overall forecast this year is for another low snowpack and more precipitation as rain rather than snow. If that turns out to be true, that will mean another drought summer in the west and potentially a fire season even longer and more intense than this year's.

I still know some people who are climate change deniers, but it is harder and harder for them to find creative ways to wish away how different the winters are than just a couple of decades ago, and the very real world impacts this is having on the landscape and on industries like farming.

The articles I've seen about the heatwave in NYC have just focused on the immediate warmth but not on other impacts -- obviously mountain snowpacks are not such an issue in the east, but there will be other issues such as the warm winter causing higher survival rates for insects or issues for plants that need a period of intense cold, say.

My friends who are parents are avoiding the topic of the weather like the plague, and if it comes up in conversation, more than one has started to cry. I think it FEELS like proof of Global Warming being real and real bad, coming so close on the heels of the Paris talks. I mean, I follow climate change science pretty closely, but I've been uneasy all fall because the temperatures make it seem so real and immediate even though I know it's largely El Niño (in a warmer world) AND I've been seeing real, dire signs for years, like crop changes and bulbs coming up a month early and problems with apple crops. Having this heat hanging over me day after day after day just FEELS like a very ominous warning.

The couple of Tea Party Republicans who have dared to make snide Global Warming comments in my FB feed have been RAPIDLY and NOISILY shouted down by parents -- not angry partisan parents, but parents who are freaking the fuck out about the children's future. You can sense the change in the topic. I wonder if, looking back, we'll see this as the year climate change really starts to become an issue "soccer moms" are willing to get very upset about and take it to the voting booth.

I thought the preferred term was climate change over global warming because the actual local changes could vary so much and could actually be cooler. Saying "ha, see the global warming now!" seems a bit counterproductive to that.

To me it's been a year of craziness and extremes in temperatures.

I grew up in Chennai, India and now live in Boston, MA.

After experiencing that crazy extreme winter in Boston at the beginning of the year, I heard about summer temperatures in Chennai breaking all previous records. Then I went home over the end of November and the beginning of December and we had record-breaking rainfall (over three times the usual amount) leading to widespread flooding. Then I get back to Boston to find record-breaking winter highs. I'm getting slightly tired of hearing the word "record-breaking". Frankly, if global warming is all about the usual weather patterns being broken and extremes becoming more likely, I believe it!

The big problem is that the jet streams, and particularly the circumpolar vortex, are not hewing to their historically stable patterns. Right now it's the monster el Nino picking up Gulf heat and moisture and sweeping it over the eastern seabord, but in 2014 it was the polar vortex dipping south and bringing air that usually stays over the Arctic Ocean to places like New Orleans.

But that's just the atmostphere. Imagine the fun we'll have when the great ocean conveyor currents like the Gulf Stream get disrupted. Wheeeee!

I'm in Wisconsin, about an hour and a half east of the Twin Cities. This will be my second winter after living in SoCal all my life, so I'm not totally sure what "normal" is yet, but it's been way warmer than last year and what weather websites tell me is the average for this time of year. We've had some snow here and there, but nothing sticking more than a day or so, while last year we had snow on the ground from the first week of November through March. There's a bit of snow on the ground now from the same system Elly Vortex mentioned, which looks like it might last - the forecast has us hitting 35 tomorrow, but that's the only day above freezing in the 10-day outlook. Looks like we'll get some snow reinforcements after Christmas, and the temps will go down to their normal spots with highs around 20.

A couple things are kind of annoying with it not being down to normal cold levels. First, since it's been right around freezing when we have gotten snow, it basically turns to slush instantly. Last year, things didn't melt until spring, so we didn't really have ice on the roads or any muckiness all winter. So, it was cold, but it want also gross like it has been this year. Second, my town has a bunch of outdoor skate rinks that were supposed to open last weekend, but they can't really even flood the rinks until the ground is frozen so it'll be a while yet before they can open them. I was hoping to sort of teachoice myself to play hockey, but no luck yet.

I'm certainly no expert, but I follow climate change pretty closely, and the best the experts and scientists are hoping for is a 2 degree C warming. That would mean a greatly changed climate, but still livable (except, perhaps, for the hottest parts of the planet.) I won't offer any opinions on whether warming over and above that will occur (I tend to think yes, because we would need to overthrow capitalism, and... yeah.)

I tend not to think that all is lost, but I certainly tend to think that everything between the tropics of cancer and capricorn will be totally uninhabitable by the end of the century, and that the ensuing population displacement will cause unbelievable chaos and suffering. Also, the oceans may end up being essentially poison, so coastlines are probably not a great place to be. I'm personally keeping an eye out for cheap land in central Ellesmere Island.

If you're seeing 2C, you're seeing the commercial media prediction, which — as always — is a pacifying lie intended to minimize our demand for change.

I've been watching the customers at the bait store/hunting supply/gas station I work at slowly get more and more worried as the weird winter this year wrecks all their hunting and fishing and outdoors stuff. First, the winter started late and stays warmer than it should in November, which pleased the farmers, but upset the deer hunters, who rely in part on cold temps to help preserve dead deer. They were in many cases just not heading out because a dead deer in 65 degree weather goes bad pretty quick, and the warmer weather keeps the deer bedded down. Bad hunting for them this year. Now, the winter has finally kinda made it to normal late december, but until the last couple of weeks any below freezing temps we had were followed by days of above freezing, and this has crippled the main winter respite of the rural Minnesotan, ice fishing. The ice is still risky where it exists, and the various opulent to shitty ice houses they own might not see use this year at all. Snowmobiling is gross in slush and skiers don't have any snow to speak of. People are actively worried and mentioning it to me without prompting. I haven't heard the spectre of global warming raised yet, but even in this super conservative area people are noticing something is up, even if it's just self interest.

Anyway, it'll be weird when the ice fishing lobby becomes a big climate change crusader. These people do not joke about ice fishing.

Sigh. The signature of climate change is not warmer temperatures in a given region in a given continent, it is more variance from the historic mean.

Sigh.

The sign of global warming is average temperatures over an extended period of time increasing over a supermajority of the planet. The variance from the mean is cause both by the warming *and* by the extra energy.

But it being warm in the Eastern and Central US has little to do with global warming and everything to do with the effect of an El Niño event on the US, which results in very warm temperatures there and much cooler and wetter weather on the West coast, and more rain in the South.

This pattern is well known to meteorology, which is why the extended range outlooks called for just this to be happening. It may be even warmer because of global warming, but the fact that this year is proving to be a very warm one in the Central/Eastern North American regions and rather cool and wet in the West is well known. And the next time an El Niño peak happens, it'll be another warm winter.

After 2013-2014? Just enjoy it.

Yes, well, sure, kinda, tautologically. But what I was talking about by using the word 'sign' is Stuff Ordinary People Might Be Able To Notice. Incremental average temperature increases over the entirety of the planetary surface isn't that, even if it is indeed what's happening.

The everyday ordinary-people word that will really sum up the simultaneous increase in temperature mean and variance is heteroscedastic.

I read an interesting article in the New Scientist around last year, where they interviewed a dozen or so prominent climate scientists and said, "Off-the-record, do you think things are really worse or better than the official science says?" They all said that things were likely worse, perhaps much worse. Consensus was that everyone tends to report the minimum possible results that they can iron-clad justify. Several pointed out that there had been a recent confluence of bad reports - clathrates, glacial coverage and temperate records - that seemed to confirm everyone's worst - but not unreasonable! - fears.

So - and I hate to be the bearer of bad news - a possible if unlikely hypothesis is that we are not going to experience climate change in the best case scenario or even average - that we get the worst case. Rather than climate change being a problem for future generations, it might even be a fairly immediate problem in this generation.

I reiterate that I think the chance is small, but it might be our world's weather has already tipped, and while there will still be variation, there will be a steady trend upward from now on, clearly perceptible at human scale time rates (decades, not centuries). This is compatible with the existing data - if we were suddenly steadily warming, we'd suddenly see a spate of temperature records set each year, just as we've seen now for the next several years. Of course, we really won't know for a few years yet...

The next few decades will be exciting regardless. I am fairly confident that humans will rise to the challenge and society and culture will survive, though I think with the onset of hard climate change, the world water crisis, and the end of the antibiotic all coming near the same time, things will get very bad in a way we haven't seen for 700 years or so...

I am absolutely confident that climate change is going to be our most pressing issue within a dozen years. For the past two decades it is the worst-case predictions that have come true. We have blown right past all the best-case scenarios. Left them in the dust. We are well beyond the tipping point. We are well into the we-are-fucked point.

This is why we finally have US politicians admitting that there is a problem, why we have a US military telling us flat-out that we have a problem, why the top twenty US consumer products corps are saying flat-out that they have to change.

Our politicians, military, and corporations have fought admitting these problems for many years: this very year, that all changed. That alone should scare the shit out of you.

The northern militaries are all doing squirts over the realization that the Arctic Ocean is soon going to be passable by normal ships. That is going to change a lot of trade and political realities.

2C is the optimistic best case scenario world governments are paying lip service towards possibly attempting. The IPCC states that we are presently on the path to 3.7 to 4.8C. And of course, 2C is the number previously arbitrarily declared as 'safe', never mind that we are discovering that even the current 1.1 degree change is unmanageable. And of course these numbers only look towards 2100 when the trajectory will continue long past this horizon. The forecasts also cannot adequately internalize the well publicized unpredictable tipping points like methane clathrates or the temperature at which forests cease to take in CO2 and instead dump it back out. We haven't seen anything yet.

And that was 7 years ago!

"The North Pole was above freezing today, on what should be one of the coldest days of the year. 50 deg F above norm."
