Jim Hansen - 20 Years of Climate Concerns

@tomtefarbror: Well, the Vikings enjoyed life during the Medieval period when it was warmer than today. They even farmed on Greenland.

The emails from the Climate Research Unit of the University of East Anglia, documenting various attempts to suppress data and manipulate scientific consensus with thuggish tactics, confirms what critics of the AGW movement have always maintained: it has a lot more to do with money and politics than science. In fact, the global-warming movement is essentially the opposite of science the manipulation and destruction of empirical data to support a theory whose accuracy was decided in advance.

This comment is interesting. Could you give us sources for your statements on emission declines in 06- 08? Thank you!

People who are in denial about global warming will never look at the proof. It's akin to denying evolution. Bush once said "It's just a theory." A scientific theory is not a philosophical theory. A scientific theory -- global warming, evolution, relativity -- is one that can make predictions about future outcomes and be correct. This is exactly what the global warming models predicted. Hansen's estimate range was conservative -- it's far worse than even he would say aloud 20 years ago.

CO2 is 0.03% of the entire atmosphere. Changing +/- by 0.001% is simply not enough to change World temperatures by ANY amount.
Think about it.

If you put 0,03% cyanide in a glass of water it would kill you if you drank it, even though "it's such a small percentage". Your argument fails.

cool interview. good questions too.

I stopped at 2:30
Climate is based upon physics & science, not chance like dice.
CO2 is a GHG, but not very powerful & with diminishing effect.

Mercury is not cold.

The CO2 on Venus is incredibly dense & a very high portion of the atmosphere. Check out the figs & don't be so ignorant.

Jim Hansen is full of CRAP....
