What They Don't Tell You About Climate Change (economist.com)
Countries are scrambling to limit the rise in the earth's temperature to just two degrees by the end of this century. But Slashdot reader dryriver shares an article titled "What They Don't Tell You About Climate Change."
No, it is not that Climate Change is a hoax or that the climate science gets it all wrong and Climate Change isn't happening. According to the Economist, it is rather that "Fully 101 of the 116 models the Intergovernmental Panel on Climate Change uses to chart what lies ahead assume that carbon will be taken out of the air in order for the world to have a good chance of meeting the 2C target."
In other words, reducing carbon emissions around the world, creating clean energy from wind farms, driving electrical cars and so forth is not going to suffice to meet agreed upon climate targets at all. Negative emissions are needed. The world is going to overshoot the "maximum 2 degrees of warming" target completely unless someone figures out how to suck as much as 810 Billion Tonnes of carbon out of Earth's atmosphere by 2100 using some kind of industrial scale process that currently does not exist.
That breaks down to 1,785,742,000,000,000 pounds of CO2, "as much as the world's economy produces in 20 years," according to the Economist.
"Putting in place carbon-removal schemes of this magnitude would be an epic endeavour even if tried-and-tested techniques existed. They do not."

Dr. Roy Spencer, funded solely by Government grants (not "Big Oil"), lays out the actual data and shows that 95% of all climate models agree that actual measured data is wrong. The models, basically, do not model actually all that well. Puts a bit of a damper on the whole "models assume we have negative carbon output!" kind of thing, doesn't it?
Browsing at +1 - no ACs, I ignore their posts. So refreshing!
Well, unfortunately, it was his own party which jumped on Three Mile Island to torpedo nuclear power in the USA. That pretty much -caused- climate change, when you think about it.
This is my sig.
