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."

That's how you know the Club of Rome and their progenitors are not interested in solving anthropogenic global warming, simply in politically exploiting the scenario to destroy capitalism.
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.
When empirical data and theoretical models don't match - which do you trust? Dr. Spencer does what any good scientist or engineer should do - go with the actual empirical data.
This says NOTHING about whether or not climate change is happening or whether or not man is causing it; what it IS saying is that the models used to predict what could happen are turning out to be quite invalid, as they do not match the actual data. When the model fails to predict or match actual measurements - it's the model that needs to be corrected, yes?

The "climate change" concern in the 60s and 70s was global cooling, not global warming. The only bit you got correct is that Carter got involved; he signed the National Climate Program Act to deal with "the global cooling crisis."
I worry for Slashdot when I see such revisionism as yours upmodded to +5.
