Just from what I've seen earlier in the thread, it would change precipitation patterns in a way that would specifically create massive droughts in China. Or maybe it was massive rainfall? Pretty sure it was droughts.

It's droughts. And yes, China stands to gain incredibly from taking point on mitigating climate change, and part of that reason is that China is horrendously, stupidly polluted at the moment: https://watchers.news/2017/01/02/red-air-pollution-alert-china-january-2017/

The U.S. election killed whatever avenues there were to go forward from here with climate change mitigation. In a household with an incredibly tight budget trying to make ends meet, Trump just walked through the door and announced with bombast that he spent our limited savings on time shares.

We didn't have 8 years to spend just waffling around at best. What we have now will be as good as it gets; if you have kids, I'm real sorry for you. They will be raising their own families in deteriorating conditions and you will have to watch it happen.
The Democrats were never going to go nuts about climate change mitigation either, especially at the federal level. They either were going to get blocked by Republicans, or drag their feet and make only the small incremental changes that aren't enough. Trump is probably going to open up drilling, stop a bunch of climate science, deregulate pollution, and otherwise make things worse, but that doesn't mean all avenues are closed. It means that collective action and movements at the grassroots level are just that much more important to participate in and expand. Now is the time to try and effect change at the state and local levels, and use organization, protests, and (one can dream) strikes to force the Republicans to do things they're ideologically opposed to.

I think this is important to point out. Hillary Clinton, as was often said, is an incrementalist. She'd have favored a much less aggressive approach than what's required, and would've been quick to abandon it, much like Obama. Her environmental record, much like his, would be significantly better than doing nothing but that would've been the best you could say about it.

If you care about climate change, and it's going to be the primary issue in our lives before too much longer, then it's time to start organizing locally. Don't give yourself the convenient excuses that individual effort is pointless or that we should've been doing this 30 years ago; start in your own backyard and see what you can get done. There's a lot of work to do here.

You're wrong about that. Trump's EPA will be nowhere near as aggressive on enforcing carbon limits as a Clinton EPA would have. Trump is scrapping the Clean Power Plan, something the Clinton team wanted to defend.

You can argue it isn't enough, but there is a meaningful difference between the impacts from "too little" versus "nothing at all"

Trillions in costs. That's what some see in inaction. And that's what some see in action, in the form of all that unsold and unburnt coal, oil and natural gas. Trump's tapped a number of the latter.

Hillary wouldn't have taken the decisive action on climate change that's required, and even if she wanted to the Republicans would block her. However it should be emphasized that Trump will be significantly worse, gutting the CPP alone will result in significantly higher future emissions and crippling the EPA will constrain America's ability to mitigate climate change for years. Trump's election was a disaster, and we're going to see exactly how much damage an explicitly anti-climate science administration can do to American scientific institutions.

I'm emphasizing this point because I disagree that carbon emissions causing climate change is a problem that can be addressed on a local level. It's a tragedy of the commons problem where the impact will be only be felt by future people (or at least at some point in the future), and the economic incentives right now reward continued or expanded use of fossil fuels and penalize regions that try to make reductions. It's exactly the sort of problem that requires national policy and/or international agreements to address. Americans really really need the Democrats to regain control of at least one of the federal houses or the Presidency, as a single unrestrained Republican administration can cause far more damage in terms of allowing future carbon emissions than any amount of local effort can address. I'd argue this should be the top-priority for environmentally minded progressives/movements.

I don't want to sound like I'm arguing against local environmental initiatives, just that significant carbon emission reductions simply can't be achieved at this level. Local efforts towards enhancing climate resilience are probably more important than ever.

On the subject of state-level efforts, despite incredible whining from the usual sources Canada's province of Ontario has as of Jan 1st started its cap-and-trade system for carbon emissions. Both Ontario and Quebec have linked their cap-and-trade system to California's and I was wondering if any other US states were planning on joining this framework?

Oh I see! This must be the Bad Opinion Zone!
A Clinton administration would have been built at the very least on the idea that you're trying your best to do what is good for people and the world. They might not agree with drastic action now, but they would agree with gathering evidence to understand the situation and can be persuaded into urgent action if the evidence is strong enough, and it becomes politically possible to fight for it. You contrast that to the Trump administration and the entire Republican, where the overall conclusions are preset. Nothing must be done, and science that points to things needing to be done is inconvenient and must be shut down. An attitude that claims simultaneously that there are too many unanswered questions, and then defunds the very methods of answering any questions.

You need the former attitude to even take a single step here. The attitude that Clinton and Trump are the same is simple collective suicide and the environmentalists need to rid themselves of this idiocy ASAP.

It's reasonable to be or to have been cynical about what Clinton would've done or tried to do. She would've been Obama's symbolic third term, with all that implies: gridlock, lukewarm central-right policies, and so on. Obama's biggest flaw as a president is how stupidly cautious he was right up until year six or so.

However, Clinton could have been relied upon to live in the world, and I think she's got a much broader mean streak than Obama, so she'd at least have gotten some fraction of the right things done. She would've been unpopular with both conservatives and liberals, of course, but that's the game we play.

Again: the idea that anything shy of major, civilization-redefining progress isn't progress is just left-wing virtue signaling. It's the modern climate movement's depression issue, where we listen to our sad brains as they tell us that the only reasonable solution is to power-chug vodka on the couch until the seas rise to drown us. Some progress will always be better than no progress, because big progress is made out of multiple pieces of some progress, and each piece of some progress is made of multiple bits of small progress.

It's also pretty poo poo thinking to condemn or ignore a promising bit of new information because it isn't part of your obvious, preferred solution. So far in 2017, we've got progress on cloned meat for general sale (six days left on their IndieGoGo crowdfunding drive), solar's getting cheaper than ever, China's making big moves in renewables and pollution cleanup because they're worried about air quality riots, India's reforesting itself like crazy and built the world's largest solar plant, and Climeworks is doing interesting things with direct carbon capture from the air.

Limiting it to 2 degrees' rise may not be attainable, but 2.5 is better than 3. 3 is better than 4. To pretend otherwise is to sit around jerking on your nihilist doom boner and contributing nothing.

Even if you're just being visibly proactive--you've limited or eliminated your animal protein intake, you make decisions with an eye on your carbon footprint, you live somewhere walkable and/or with effective mass transit, you deliberately limit how much gasoline you're responsible for burning, you're an intelligent and constructive contributor to discussions about a complex topic--that's still something you're doing to boost your local situation, and something is always better than nothing. Societal shifts always begin on the individual level.

Extrapolate the argument to other areas of endeavor, and it becomes increasingly and obviously ridiculous. It's the same argument that you see right-wing politicians use to try to defund programs they don't like; the problem may have improved, but it's not gone, so let's abandon the solution.

Guy McPherson's doomsday cult notwithstanding, I think the general view is that even in worst case scenarios, climate change will not cause outright human extinction. So yes, even if civilization collapses and the earth is only habitable for a few million people around the poles, it would make an immense difference.

Nobody actually believes that Clinton would have taken any serious action on climate change, do they? Even if you weren't paying any attention to the last election anyone can see that she represented little more than Obama's third term, which is quite obviously not enough to do anything relevant or substantial with regards to climate change. Climate change is no longer a political issue on the national scale in America at all, I know I've said it before but Clinton didn't bring up climate change a single time after the primary.

If it makes you feel better you can work towards change on a local scale and pretend like there's gonna be another Bernie Sanders in 2020 to take Trump down with their hands tied behind their back, but the 2016 election doesn't really matter much in the long run. The ultimate truth of the matter is that it was game over 16 years ago when Al Gore conceded the presidential election. America isn't omnipotent, it can't just save the world by putting Bernie Sanders or Jill Stein or someone at the wheel, nobody's going to be able to freeze the arctic again once it's gone, nobody's going to be able to build a giant vacuum cleaner to magically suck all the CO2 out of the atmosphere.

But my point is that these movements already exist for the purpose of getting Democrats elected (and having any chance of making significant carbon emissions reductions). The Sierra club and similar environmental lobbying groups, unions and the Democrat party structure itself. When it comes to reducing carbon emissions, environmental progressives don't need to reinvent the wheel but should join their local branch of the Democrat party (if they somehow haven't already) and work on taking back state level houses. Getting Democrats in power federally is a necessary (but not sufficient) condition to making any progress on carbon emission reductions in the US. The next step is getting real progressives in charge of the party because as others have already noted incrementalists like Clinton will not take the decisive action needed on climate change.

I get what you're saying, but Clinton would have been significantly better than Trump if only because she wouldn't be waging war on the EPA and climate research funded by the US govt. I'm sympathetic to Obama on the issue of climate change, I suspect he understands the critical importance of climate change but you just can't do anything substantial with a Republican house.

In the bigger picture America is a conservative country (by design) and probably was never going to take the lead on mitigating climate change. However full Republican control of govt is going to make things worse than they needed to be.

A lot of it depends on unknowns as well. How many nukes do India and Pakistan have? Nobody is entirely sure. Will other nations also launch theirs? Who the gently caress knows? How many nukes does it take to cause nuclear winter and how many does it take to raise the background radiation to unacceptable levels? Again who the gently caress knows?

It's one of those things where the answer is "no matter what happens it will be bad so let's please just never find out, tia." There is just no way a nuclear war of any type anywhere on this rock is anything other than "completely loving awful" so nobody wants to start one.

Essentially even a "limited" "regional" nuclear war -> climate disruption -> lowered agricultural production -> nations panic, govts respond by hoarding food -> prices skyrocket and potentially 2 billion people experience famine, including in developed countries like Japan that rely on food imports.

In good news, Arctic sea ice extent actually ended up in 2nd lowest a few days ago. In less good news, yesterday it dipped back down to record lowest again.

In bad news, area had not quite caught up even then, and is now trending down with extent.

In worse news:

quote:

About 30 years ago, climate researchers became concerned that AMOC could suddenly shut down as a result of anthropogenic climate change. The “paleoclimatic record”—that is, what the planet’s geology and fossil record reveal of previous global climates—showed that the AMOC has rapidly collapsed in the past. “Rapidly” here means “within the span of a human lifetime.”
Yes, this sounds familiar.

quote:

But as climate models improved, those fears dissipated. “No current comprehensive climate model projects that the AMOC will abruptly weaken or collapse in the 21st century,” wrote a team of NOAA researchers in 2008. “We therefore conclude that such an event is very unlikely.”
As does this...

quote:

The most attention-getting of this work: a paper last year by James Hansen and 18 other scientists that argued the AMOC’s collapse could threaten global civilization this century. The paper built on older work showing that huge injections of freshwater have historically destabilized AMOC, essentially by flooding the Atlantic with cold water and screwing up its finely tuned density cycle
And this...

quote:

This week, the consensus on AMOC was challenged again. A team of researchers have showed in Science Advances that a popularly used climate model may significantly overestimate the stability of AMOC. Once you account for this bias, AMOC proves much more likely to collapse, they argue. And this collapse could happen without any freshwater injection from Greenland.
Uhh... okay this is new.

quote:

That’s because climate models make AMOC more stable than it actually is in nature, said Wei Liu, an oceanography researcher at Yale University and one of the authors of the study. “In a stable routine, if you increase the CO2, then AMOC only weakens. But in an unstable routine, if you add global warming, then AMOC will collapse by itself,” he told me.

He argues that field observations of the Atlantic Ocean suggest that AMOC is in fact unstable. Between mid-2009 and mid-2010, AMOC appeared to weaken, with the current carrying only two-thirds of its usual volume of water. At the same time, sea-level rise on the East Coast accelerated and Europe experienced an unusually frigid winter.
Let's celebrate the good loving times!

quote:

Hansen, on the other hand, was more dismissive of the study’s approach. “You can’t fix the climate model simulation via ‘bias removal’—you should fix what is wrong with the model physics,” he said in an email. “They are doubling CO2, letting that change the temperature, rainfall, etc. and seeing what that does to the AMOC in their model. It’s been more than 35 million years since we had that much CO2 in the air, and sea level was more than 200 feet higher then. If we (humanity) are so stupid as to double CO2, you can count on the AMOC to shut down much faster than 300 years.”
...
“This is an important step forward,” said Jean Lynch-Stieglitz, a professor of Earth and atmospheric sciences at Georgia Tech. “This study identifies a specific property of the climate models that would tend to make the AMOC in the models more stable than in reality.”
I mean, there's an actual debate here, compared to denier bullshit.

For once I hope fishmech or someone takes this opportunity to tell me why this paper is obviously wrong, because thinking about it makes me very depressed.

Several hundred nuclear weapons have been detonated is tests over the last 60 years. The Russian Tsar Bomba alone was as powerful as a good chunk of Pakistans arsenal put together. A few dozen mid sized nukes, of the several hundred kiloton to the 5 to 15 megaton range, does not spell global destruction.

Here is what an all out nuclear war between India and Pakistan would look like.

1. India and Pakistan major cities destroyed of course. Several million dead in the major cites. Several million dying later from starvation and lack of clean water as society breaks down. Hundreds of thousands of people in small somewhat independent villages would be unhurt by the blasts and continue on with their civilization, although at a lower level. Lifespans in those towns would be 10-20 years lower because of an increase in cancers and such.

2. Chaos in the middle east as millions of starving refugees try to enter. Stronger countries that can control their borders, like China, would probably machine gun refugees on the border to prevent the overwhelming of their own societies.

3. The bombs and the burning of cities would cause a local nuclear winter. For about a decade the temp would be lower and crop production would be lower in Asia, the equilvent of a large volcano and nothing the world hasn't seen dozens of times before.

4. increased instances of cancer in Asia and Europe. Again nothing we haven't seen before. Concerns over the few hundred nukes set off during decades of testing is what led to the testing ban.

5. Hundreds of millions of people in North America would see almost no physical effects from the war.

6. A worldwide depression would follow the removal of India and Pakistan from the world economy.

Basically, even if a major disaster obliterates a whole region, the other regions of the earth contain large chunks of industry and several hundred million people who will go on with civilization.

Even a worst case climate change scenario that saw the tropics become a desert and the middle east become a mad max wasteland would still have tens of millions of people continuing modern civilization in Canada, Siberia, and Northern Europe.

I don't mean to be flippant here. We should fight as hard as we can for a better world, and any realigning of our civilization would result in millions killed in upheaval, but we would still adapt and survive. Short of a worst case Venus scenario, or complete ocean death causing oxygen content in the atmosphere to drop, or an asteroid strike by a dinosaur killer, I don't think humans can be wiped out.

In 300 years, it may very well be that the tropics are uninhabited, and the poles ice free, and several island nations submerged, and the coastlines rearranged, but life, even something resembling the comfort of the modern 1st world, would go on in the northern latitudes. So fight as hard as you can but remember that defeatism is bad.

If you sent a space colony ship out into the galaxy and found an uninhabited planet that looked like earth 200 years from now in a worst case scenario, it would still be a good place to set down and colonize. The biggest killer from climate change isn't going to be climate change itself, its going to be the societal upheaval as we fail to adapt. Even if it gets to the point that warming can't be stopped we could still work to adapt.
