It's the final call, say scientists, the most extensive warning yet on the risks of rising global temperatures.
Their dramatic report on keeping that rise under 1.5 degrees C says the world is now completely off track, heading instead towards 3C.
Keeping to the preferred target of 1.5C above pre-industrial levels will mean "rapid, far-reaching and unprecedented changes in all aspects of society".
[...] After three years of research and a week of haggling between scientists and government officials at a meeting in South Korea, the Intergovernmental Panel on Climate Change (IPCC) has issued a special report on the impact of global warming of 1.5C.
The critical 33-page Summary for Policymakers certainly bears the hallmarks of difficult negotiations between climate researchers determined to stick to what their studies have shown and political representatives more concerned with economies and living standards.
Despite the inevitable compromises, there are some key messages that come through loud and clear.
"The first is that limiting warming to 1.5C brings a lot of benefits compared with limiting it to two degrees. It really reduces the impacts of climate change in very important ways," said Prof Jim Skea, who co-chairs the IPCC.
"The second is the unprecedented nature of the changes that are required if we are to limit warming to 1.5C - changes to energy systems, changes to the way we manage land, changes to the way we move around with transportation."
"Scientists might want to write in capital letters, 'ACT NOW, IDIOTS,' but they need to say that with facts and numbers," said Kaisa Kosonen, of Greenpeace, who was an observer at the negotiations. "And they have."
The researchers have used these facts and numbers to paint a picture of the world with a dangerous fever, caused by humans. We used to think if we could keep warming below two degrees this century, then the changes we would experience would be manageable.
Not any more. This new study says that going past 1.5C is dicing with the planet's liveability. And the 1.5C temperature "guard rail" could be exceeded in just 12 years, in 2030.
We can stay below it - but it will require urgent, large-scale changes from governments and individuals and we will have to invest a massive pile of cash every year, about 2.5% of global gross domestic product (GDP), the value of all goods and services produced, for two decades.

Ok, let's take this seriously. Stop ALL rocket launches, ALL commercial flights, and remove ALL i-c-e's over 3.0L from the roads. Sorry Bubba, no more v8 5.7L trucks. No more AMG 6.3L Mercs, no more Dodge Vipers, no F1 or F-anything racing. In terms of trade and services, what stops, stops. Tough. We re-invent and are forced to go local.

And if you have more than two children the extra ones have to be killed. I mean, if we're taking AGW seriously...

No no no no... everyone knows the solution is massive amount of government spending on trickle down economics, after all why just solve a problem when you can solve it and line yours and your cronies?

This would be reasonable. It's not like the system wouldn't work without all that, in fact it has for thousands of years.

Except you didn't take it seriously at ALL. It has nothing to do with F1 racing or rocket launches or v8 10L trucks. It has everything to do with lack of policy so that on average we are not driving V8s but electric, and V8s are banned from *MASS MANUFACTURING*.
If I take a dump on the street, someone may post it on youtube how an idiot took a dump in the street. If 1000000 people do that in one city one day, you probably have a major fucking problem. Scale. That's the problem. 1 Bubba with a pickup is not a problem. 100 million Bubbas with their pickups are.

San Francisco?

I read one story about how so many people pissed and shit on a lightpole at one corner that it collapsed. It was nearby where a tree had no branches because crackheads kept cracking them off to declog their pipes. The tree had already been replaced 4 times due to this.
I wonder what the opinion about climate change is in San Francisco.
