Climate Science: 50 Years Later

What have we learned about climate science in the 50 years since PCAST's first warning on the effects of accumulating carbon dioxide in the atmosphere?

Five decades after the first climate change warning to an American president, the signs are apparent. Global temperatures have increased, extreme weather events are more common, and species are fleeing their habitats.

Climate Science, 50 Years Later, the 29 October symposium at the Carnegie Institute of Science in Washington, D.C., assembled more than a dozen prominent scientists who recounted the damages caused by climate change, reflected on the past, and considered how best to respond to an increasingly challenging future.

What a load of BS....and scientists who don't agree don't get funding. FFS, so much evil on this planet.

50 years ago, people were talking about the fact the earth had been cooling since 1940's. Now those people say that it never happened. What is really funny is the guy that is pushing it big time, Hansen, co wrote a paper talking about the cooling temperature but now claims it never happened.
