New climate change science explained by Peter Sinclair, just back from a scientific expedition to the Greenland Ice Sheet. Sinclair explains the feedback effects of melting ice, and the impacts on the northern polar jet stream and mean sea level.

Sinclair leads educators on climate science and created the Climate Denial Crock of the Week video series, which tackles myths about global warming, the greenhouse effect, and carbon dioxide pollution.

Sinclair proposes moving towards wind and solar as the key to jobs and future energy needs.
