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.

    I wonder why this is always the case when people complain about global warming and are anti-vaccine but not against other sciences.

    Why aren't they anti-gravity, anti-momentum, anti-special relativity, etc. It's not like we have perfect understanding and consensus on anything in science.

    Because there aren't people making money hand over fist off of anti-gravity, anti-momentum, etc.

      All the money and control over people's lives is decidedly on the side of those who support "climate change".

      Governments want to tell you how to live, what kind of light bulbs to by, how your car should run, and to gain control of entirely new energy sectors. That's why they cannot abide "deniers".

    Here's a presentation [youtube.com] and associated paper [vixra.org].

    It's just that there's no power or money to be gotten from supporting special relativity; ergo, nobody gives a shit that some "cranks" are disputing it.

      Apparently, that link to the paper is incorrect; it's some abridged version or something.

      This looks more like the right one [sciencepublishinggroup.com].

    Proponents of global warming and vaccination want to force themselves into peoples lives. Not so much regarding gravity, although I bet you'll find very few global warming or vaccine skeptics who also find dark matter acceptable once its explained to them. But even so, there isnt much reason to care about it.
