Climate Change and Extreme Weather

A summary of predictions and link to the original report. In a nutshell, we are fucked; climate change effects are already in progress. We are extra specially deeply fucked sideways if people keep going on the current trajectory. We are only slightly rudely fondled if maximum effort is made to undo the damage immediately. Which is not really news, just a more refined description with better resolution and fresher examples, than what people have been saying for the last several decades.

It's all going to be really fucked, regardless. D:

Massively altered climate system, massive collapse of civilization -- and that one could turn fast, fast.

The phrasing I've seen is "rats, roaches, and jellyfish." 0_o Not my ideal set for totems or ecology.

Based on my understanding, I'd say the odds of all that happening is about 30% within 100 years...
Re: Thoughts
Date: 2012-11-20 10:26 pm (UTC)Exactly. It's difficult to break, but possible and within range of our species-wide influence now.
A key thing that worries me is, almost nobody pays attention to it. It's too obscure. It's a huge thing and crucially important, but most people don't even know it exists let alone what it does or how it could break or what we should do to prevent that.
And that's one that at least a handful of people DO know about. How many things are there in the environment that are crucial but we don't know could cause a fatal collapse? Because I don't want to bet the survival of humanity on whether we know everything.

Re: Thoughts
Date: 2012-11-20 10:23 pm (UTC)I agree that they are valuable, precisely because they're tough and adaptable. But the strength of a biosphere lies in its redundancy -- the diversity and fault tolerance it has. So anything that drastically reduces diversity is bad.

Date: 2012-11-20 03:05 am (UTC)I have to admit, even though climate change IS an extremely important issue, I sort of get irritated with how much exposure it gets when there are other pressing environmental issues. It's gotten to the point where I see things thrown under climate change that don't actually have that much to do with climate change (a LOT of what you see about the ocean is actually only marginally true for climate change, but much more true for what's going to happen if we keep overfishing/dumping poisons/allowing a lot of boat traffic in many areas) just because that's the only way environmentalists can get their voices heard anymore.
Climate change is a problem, but it's one of many and our world will be just as rocked if we let the ocean ecosystems collapse due to our combined efforts to fuck it up in other ways. It will also be just as rocked if our population continues to explode out of control while we lose more and more farmland. Etc. /my soapbox
Well...
Date: 2012-11-20 03:25 am (UTC)So am I. However ...
>> So, while *we* might be fucked and while some species might go extinct or bottleneck, the Earth is really just going to swallow whatever we do to it and spit out the decaying bones of our civilization for whatever comes after us. <<
... "some species" already registers similar to an asteroid strike. I'm not happy that humanity's contribution to evolution is equivalent to hitting the Earth with a big rock. Yes, the biosphere will survive, but it really sucks to have evolved all these awesome life forms and then lose a majority of the complex and refined ones while the system gets smacked down to rats, roaches, and jellyfish.
>> much more true for what's going to happen if we keep overfishing/dumping poisons/allowing a lot of boat traffic in many areas <<
I agree that there are a great many environmental problems, some with shorter fuses.
Re: Well...
Date: 2012-11-20 04:19 am (UTC)It's all kind of a moot point, though, because unless we do have an attitude adjustment, these things might die off anyway because we think collapsing ecosystems in every way possible (erosion, clear cutting, over development, introducing species) is a Fun Thing to do. My issue with putting all of these things under "Climate Change" is that 1) the predictions when it comes to wildlife are ehhh (like I said, predicting how wildlife will respond to something is a bit like flying blind), so people don't really listen unless we're talking polar bears and 2) many of the animals that are sensitive enough to be that impacted by climate change are already up shit's creek without a paddle (corals, for one) and will probably be gone(r) long before climate change predictions say they should be because they're dying from 100000 other things, too, that nobody is really talking about.
(Also: rats are really, really complex and cool, evolutionarily speaking. We only hate them because of the plague. If something says "rats, roaches and jellyfish" be very skeptical, because the only similar thing about those three things is that they are generally considered "gross" and "common;" they all operate on different levels of complexity and in different "systems".)
*We don't really know each other well, so just to clarify that I'm not talking out of my ass here (heh): I'm about three weeks away from being done with a wildlife conservation degree and do have ~real world~ experience in wildlife management + talk/think about this stuff every day. I had to go out of my way to take a class focused on climate change because it's a footnote in the big book of wildlife issues today.

Date: 2012-11-20 02:44 am (UTC)On the 16th, Neven's Arctic Sea Ice blog had a discussion of / link to (http://neven1.typepad.com/blog/2012/11/arctic-methane-why-the-sea-ice-matters-.html) "a video from the Arctic News blog, which is run by the people from AMEG (Arctic Methane Emergency Group."
The video report -- filmed this spring, before summer's incredible string of Arctic warming and ice-melt records -- shows some of the world's leading experts on methane clathrates discussing recent findings and trends. They look terrified.

Humans, on the other hand, need to be slapped over the head with a baseball bat in order to notice things they don't want to see, especially things that would require disciplined changes in behavior.
Their respective behavioral hysteresis curves are like the difference between giving an atom a charge, and trying to align a permanent magnet. One jumps when the signal occurs, the other eventually grinds their way over and then doesn't want to move.
