Do you all honestly think that the US or what people there think is the biggest issue effecting pollution? Last time I checked as a nation we are working hard to reduce emissions have some of the lowest in the world. Perhaps it would be more useful to go and bash China and India, two countries in which seeing a clear sky in a large city is a rarity.
No facts to back this up? The USA is no2 in total emitter of greenhouse gases and no2 in per-capita emissions and no1 in cumulative emissions:

#33This is precisely why Dr. Guy McPherson has predicted human extinction on earth by 2030. Methane clathrates coming from the Arctic sea floor and from Canadian and Siberian permafrost. This is the most serious threat we face now.
So, this sort of thing must have happened in past warm periods. Yet life survived.
I can't believe there are people willfully obtuse enough to still be putting out this strawman. No one credible is or has ever claimed "the end of life" or even "the end of multicellular life". Humanity could get wiped out entirely and "life" would be fine for a few billion years until it really would get wiped out completely without intelligence. But even a few tens of millions let alone hundreds let alone billions is something we might reasonably want to avoid don't you think? Is this really such a hard concept for you to grasp? When "life survived" previous mass extinction events you should read that as "SOME life survived, and often not the big complex types."

#34Well this is pretty much the beggining of the end then.
Can you elaborate please? How is this the end?

So is it time to kill myself yet?

Another fun angle to consider. Ocean acidification leading to a die-off of phytoplankton (the oxygen tank of the Earth, basically).
This could cause a global asphyxiation event.

Life != human life. That's the fallacy many in the green-movement miss. It's not about saving the Earth, Earth will be largely fine. Climate management is about saving humans.

Not always - there have been 5 mass extinction events on earth. 250 million years ago 96% of species died due to runaway greenhouse gases from volcanic eruptions in siberia. A positive feedback mechanism kicked in. Eventually negative feedback stabilized the earth - but in a new climactic equilibrium.

That's why I keep hitting "refresh" on this page of comments, in the hope that someone with more expertise than I have comes along and tells me it's not nearly as bad as I take this to be (i. e., "we're fucked").
Still waiting, BTW.

If we can't figure out an engineering solution to this problem then it's game over. It always amazes me how much people and governments focus on prevention when it comes to climate change, knowing full well it's far too late to change anything by reducing carbon emissions. If we can't sequester these 'surplus' gases from the atmosphere then I guess you could say we don't have a chance in hell, pun intended, of surviv…
Yeah, exponentials are tricky. By the time danger is clear, it's too late to do anything about it. But hey, at least this will probably be self-limiting. Disruption will arguably reduce population and industrialization, and so CO2 emissions will drop.
And then good luck rebuilding civilization now that every easily accessible resource has been mined/harvested out.
