Cold Spring Linked To Dramatic Sea Ice Loss

hrvatska writes "An article at Weather Underground reports that researchers have linked large snowstorms and cold spring weather across Britain and large parts of Europe and North America to the dramatic loss of Arctic sea ice. It is thought that the Arctic ice loss adds heat to the ocean and atmosphere, which shifts the position of the jet stream, allowing cold air from the Arctic to plunge much further south. Researchers expect that a warming Arctic ocean will drive more extreme weather in North America and Europe (abstract)."

    Katrina was a freak, but that last catastrophe of a storm is just progressive weather change now.

    That part of the world sees dozens of such cyclones every year. There was nothing odd about Katrina other than a city happened to be in the way.

      Weather is not climate and global warming is not climate change.

      One more time:

      1) Radiation in and out are the only methods of changing the average temperature of the earth.

      2) The sun emits radiation from the near-infrared range up through UV.

      3) When molecules absorb radiation, the reemit it in a random direction.

      4) Oxygen absorbs and reemits UV radiation, spitting most of it back out into space.

      5) Atmospheric gasses are transparent to visible light, so the visible light radiation is absorbed by the surface of the earth.

      6) the surface warms, and reemits lower energy thermal radiation (IR).

      7) So-called "greenhouses gasses" like CO2, water vapor, and methane which make up only small parts of the atmosphere are opaque to IR radiation. They absorb this radiation, gain energy, and physically collide with the other gasses in the atmosphere, heating them. Nearly all heating of the earth's atmosphere is from this interaction.

      8) The GHG's then emit an IR photon in a random direction, where it is reabsorbed by another molecule and reemitted on and on until it happens to ping pong out into space, radiating heat away from the earth.

      9) The higher the concentration of these trace gasses in the atmosphere, the longer it takes for a photon to leave earth, and the warmer the atmosphere is, on average.

      10) Man burns lots of long chains of carbohydrates which result in a forced higher concentration of CO2. This happens slowly over time.

      11) Plants do not gobble it all up, because plants don't live on CO2 alone. Some of it dissolves in the ocean, causing ocean acidification, which is a completely different problem. Regardless, enough of it stays in the atmosphere.

      12) The earth slowly warms because of CO2 forcing. Additionally, higher average temperatures result in more water vapor in the air, and water vapor is an even more effective green house gas than CO2. This leads to the "runaway" greenhouse gas effect.

      13) This process that produces higher average global temperatures from man-made activities is called anthropogenic global warming.

      14) While the global mean temperature is higher, local average temperatures will certainly vary. Some places will become warmer on average, some cooler, some wetter, some drier, on average, than before.

      15) These average changes at different points in the year change the overall climate of those places. This is called climate change. It is a product of global warming.

      16) A changed climate results in different weather patterns for an area than the weather patterns that existed before climate change.

      17) The weather, as influenced by a changing climate as a result of global warming, is not necessarily warmer in every region of at all times. It is simply different than it was.

      This should not be complicated for an educated audience to comprehend.

    I'm a geologist. Yes, looking on that kind of timescale (or vastly longer) gives you a useful perspective. On the big scale of things, is life on Earth going to end because of anthropogenic climate change? No. It's seen much worse. Is the expected change going to be worse in magnitude or rate than any other climate event in Earth history? Heck, no. Or even as long as humans have been around? Again, no. Humans grew up as a species through multiple glacial-interglacial cycles. We're adapted to them, at least during the times we mostly lived in caves. The waxing and waning of continental ice sheets and the realization that (for example) the place I'm at used to be under a couple of km of ice 20000 years ago kind of puts things in perspective.

    Meanwhile, on regular human scales rather than the scale that geologists usually consider, the scale of change expected over the next century is rather frighteningly fast, and it's going to affect temperature, precipitation, all sorts of things. Human societies and agriculture are a lot more fragile than life as a whole is, or humanity as a species is, so saying "It's not so bad when looking at the long view" isn't really much of a consolation. We haven't driven through a significant climate change during industrial times. Human history has shown that these kind of relatively mild changes will likely provoke mass migrations, famine, and often wars over limited resources as the local conditions change for the better or worse. Maybe industrialized society will make us a bit more robust to it, but it's still going to be stressful. You can't solve problems easily if you're (for example) turning parts of the midwest USA back into increasingly arid sand dunes, or drowning significant coastal areas. It can be done, but it's expensive and there are practical limits where it doesn't pay off even if it is technically possible.

    So, yeah, do get a longer perspective, but keep in mind that 100k years is freaking long compared to the duration (so far) of modern human society. Even the transition from full-blown glacial maximum to the interglacial we are in now still took several thousand years to complete.

    The analogy I've often used is going down a ski slope. Sure, long-term it's a gentle slope going downhill that is quite manageable. But that doesn't mean you can ignore the smaller-scale ski jump or the trees that are right in front of you. You have to pay attention to both. And if you can't deal with the short-term stuff, the longer-term stuff is kind of irrelevant. We'll deal with long-term glacial-interglacial cyclicity eventually, if we make it through the next couple of centuries as an industrial society without killing most of each other off. Otherwise, maybe it's back to subsistence in caves for a small fraction of us that survive. We do know that works long-term. Industrialized society is still early in the game.

    For the first major chunk of your post-1780 period, immigration largely fueled continued Westward expansion --- with the associated continued internment and extermination of natives, squeezed into ever less hospitable reservations with endless promises of "this is the last time we'll break the treaty and make you move elsewhere".

    Initial and later immigration waves were also welcomed to provide disposable labor for the mills and mines, under horrific conditions (which certainly count as violence against humanity). As with potential climate refugees, refugees arriving for a short, miserable life of hard labor might have been a bit better off than starving in various famines back home --- but they arrived to exploitation and contempt, rather than welcome as fellow human brothers and sisters (hardly a model for a nice way to treat people forced from their homes by our Hummers).

    As the population stabilized to fill Capital's need for labor, the immigration influx was cut off. The Immigration Act of 1924 made sure that "undesirable" Eastern Europeans (including Jews fleeing shortly before and during the rise of fascism) would be under strict quotas. While nationality quotas were officially eliminated in 1965, the free flow of anyone-who-wants-to-come immigration remains severely curtailed through the present day. Entry through official or unofficial channels is difficult, expensive, and/or dangerous. Immigration policies set a steady, controlled rate of influx to serve the needs of corporate masters (whether tomato-pickers or high-tech H1-B workers), rather than to fulfill the desires of everyone who would rather be here.

    So, does America provide a model for how to relocate huge swathes of refugees? Not at all --- we're already letting in only a small trickle of applicants, and will gun down people at the border for circumventing the quota. Past cases of more liberal immigration policy depended on historical specifics that no longer exist: land to grab from natives, or a deep shortage of the unemployed for bottom-rung manual labor. We sure won't be taking in whole populations from African countries, and nor will any of the other developed countries (if anyone was willing, they'd have immigrants pouring in already), beyond the usual trickle of just enough to maintain a cheap labor pool.
