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.

Oh fuck off already. Just admit that you will NEVER accept climate research because you have some kind of perverse emotional investment in the status quo and are unwilling to accept that you might possibly be responsible, even indirectly, to the fact that in less than a century the world as we know it will be so disrupted that it will cause untold economic loses, war, and a heck of a lot of human suffering in general.
Seriously, you hold up one random student's supposed audit of data (from some blog that doesn't even say what kind of PhD the student is working towards) and claim that that is enough to invalidate the work of hundreds of scientists from all over the world?
Never mind that we are *already* seeing the results of climate change with multiple back to back record temperatures, increasing # of storms and increased storm intensity. But no, like a typical right-wing denier you desperately cling to every lie you can get your hands around because you, to quote, can't handle the truth.

I grew up with liberal parents in a very liberal area and the late teen and early adult years were rough ideologically because I still had to learn how shitty the world was, how many bad things are done by the government. I always figured the government was too big to get away with the horrors that it does, that someone would SAY SOMETHING.
My point is that the world is a pretty crazy place and fully accepting the depth of the shitshow can be more than one mind can take. It takes time and at least the majority of counter arguments are no longer "climate change isn't real!" That doesn't excuse the person you are railing against, I just wanted to share my little insight into how humans come to terms with "the truth". It is often a slow process, more so for society at large due to the group effect.

Don't worry. We understand. You illustrate this truth every time you post. So when do we kill all men, who are not angels, so that angelic women can implement an anarcho-capitalist utopia? We're going to need to do it quickly, because the last time capitalism, as implemented by men, who are not angels, was at this level of crisis, nobody had nukes. Now everybody has nukes, and while I realize that N-day won't be the end of all life on earth (look at Chernobyl), I think we need to step up the timeline. I'm deeply concerned for the Earth Mother, and anarcho-capitalism seems like the perfect system to enable angelic women to begin fixing the damage men, who are not angels, have caused. The angelic nature of women will guide them to a deep understanding of enlightened self-interest that men, not being angels because they lack wombs, cannot ever comprehend.

What exactly is the problem here? Let's read the complaint rather than issue yet another argument from authority.
While some of that is just shoddy data collection, some of it is possible evidence for biases that would exaggerate warming since the beginning of the industrial era.
And? It's not that much to go on since none of those observations, such as they are, tell us how fast warming is occurring.

You remind me of someone that argued how seat belts are idiotic and cause deaths because you will not be able to escape a burning wreck as you get tangled up in them.... I've heard that over and over and why that person never wears seat belt.

See the "data"? Seems it's kind of warm out there?? I see a lot more red than blue. Yeah, magic data page.... who would have thought!
