In this post, I made reference to the now-debunked "hockey stick" chart made famous by Al Gore in his movie, An Inconvenient Truth.
For those who care about issues of global warming but who are not familiar with the story of the hockey stick chart, how it was debunked, and the significance of its debunking on global warming science, this post by Bishop Hill is a must read.
