At 412 ppm and rising, experts said temperature rises of 3-4C are likely now locked in.
“There is a widespread view that a +4ºC future is incompatible with an organized global community, is likely to be beyond adaptation, is devastating to the majority of ecosystems and has a high probability of not being stable.”
Professor Kevin Anderson, Tyndall Centre for Climate Change Research (Video, 58:00)
“We have already observed impacts of climate change on agriculture. We have assessed the amount of climate change we can adapt to. There’s a lot we can’t adapt to even at 2C. At 4C the impacts are very high and we cannot adapt to them.”
Rachel Warren, University of East Anglia
“There is a growing sense of panic in those who really understand what a 4°C world might be like.”
Prof. Will Steffan, Director of the Australian National University Climate Change Institute
“Thinking through the implications of 4 degrees of warming shows that the impacts are so significant that the only real adaptation strategy is to avoid that at all cost because of the pain and suffering that is going to cost.”
Prof. Neil Adger, University of Exeter
“…there is also no certainty that adaptation to a 4°C world is possible. A 4°C world is likely to be one in which communities, cities and countries would experience severe disruptions, damage, and dislocation, with many of these risks spread unequally. It is likely that the poor will suffer most and the global community could become more fractured, and unequal than today. The projected 4°C warming simply must not be allowed to occur.”

“If we don’t reduce greenhouse gas emissions and ultimately stabilize CO2 — and we also have to draw down a lot of carbon out of the atmosphere. If we don’t achieve that, there’s no real prospect for a stable society or even a governable society…”
Jason Box, Prof in glaciology at the Geological Survey of Denmark and Greenland
If you read the chronicles of the early 5th century AD, you get the impression of total mayhem, with barbarian armies crisscrossing Europe and few, if any, Roman nobles and commanders trying to defend the Empire. Most of them seemed to be maneuvering to find a safe place where they could find safety for themselves. We don’t know what was the final destiny of Rutilius Namatianus but, since he had the time to finish his poem, we may imagine that he could build himself a castle in Southern France and his descendants may have become feudal lords. But not everyone made it. For instance, Paulinus of Pella, another rich Roman, contemporary of Namatianus, desperately tried to hold on his possessions in Europe, eventually considering himself happy just for having been able of surviving to old age.
We see a pattern here: when the rich Romans saw that things were going really out of control, they scrambled to save themselves while, at the same time, denying that things were so bad as they looked. We can see that clearly in Namatianus’ poem: he never ever hints that Rome was doomed. At most, he says, it was a temporary setback and soon Rome will be great again.
For more than 30 years, the science has been crystal clear. How dare you continue to look away and come here saying that you’re doing enough, when the politics and solutions needed are still nowhere in sight. You say you hear us and that you understand the urgency. But no matter how sad and angry I am, I do not want to believe that. Because if you really understood the situation and still kept on failing to act, then you would be evil. And that I refuse to believe.
“As the temperature rises, the patricians will seek refuge as polar migrants, or set sail on heavily armed ocean liners. Millions more will live in underground cities, anywhere to escape the sun. Dazzling reports of new methods for sopping up the gigatons of carbon dioxide will create ripples of enthusiasm and then fade in the next news cycle. Fisheries and agriculture will collapse, drugs will provide little solace, and everyone will curl up in a foetal position in the end, like the ash-entombed victims at Pompeii, whimpering in the inescapable heat. The likelihood of this outcome increases as the years pass and the smoke rises.”

Climate activism is a good little racket. We throw them money, power and fame because we fear the apocalypse, but when the apocalypse doesn’t arrive they can say they prevented it. — NOS4A2
Deny what? Climate change? Only a fool would deny the climate is changing. It has been changing ever since there was a climate on Earth to speak of. — Tzeentch
But all this doomsday rhetoric? Pure nonsense. Wasn't the end of the world through rapid climate change already scheduled to happen once in 2008 and then in 2012 as well? — Tzeentch
Exactly this. — Tzeentch
Massive social mobilization would probably be required. Because of the economic impact of the policies that are now required, we're looking at the equivalent of a global communist revolution. — Echarmion
Anything that further increases the power or even just the credibility of the ruling political class is not desirable. I don't trust them, climate change or not. — alcontali
I'm saying there will be no doomsday. — Tzeentch
The climate changes both because of natural phenomena and mankind's influence. — Tzeentch
Do you agree that anthropogenic climate change has a significant impact on the climate, i.e. that it could lead, within a century, to a rise of average temperatures by several degrees? — Echarmion
Hmm. SO this is based on - hope? — Banno
You are of course sufficiently erudite to be aware that we are already in throws of a mass extinction? — Banno
It's highly questionable whether such a rise in temperature would be caused by man, considering the world has been steadily warming up long before man started burning fossil fuels and we are currently living in a cold period in the Earth's history, making a rises in temperature not just likely, but also inevitable. — Tzeentch

So, bringing me back to my three questions:
a) CO2 does not have the physical characteristics that cause it to trap solar radiation in the earth's atmosphere.
b) An increased concentration of CO2 in the atmosphere does not strengthen the effect.
or c) CO2 concentrations are not increasing?
What do you think isn't happening? — Echarmion
I'm saying there will be no doomsday. — Tzeentch
