Arctic Ice Melt
The Arctic Ice is melting at an alarming rate, which could leave the North Pole virtually ice free within 10 to 30 years. Paleoclimate analysis indicates that the Arctic has probably not been ice free for about 3 million years.
The History of Climate Science
While the 'Greenhouse Effect' has been known for nearly 200 years it was not until the 1950's with the aid of studies funded by the US military that the major components of the theory were well understood. This largely had to do with understanding the atmospheric composition in the stratosphere but there are many interesting pieces to the puzzle of climate science.
