Hockey stick graph

I have been reading a lot about the science behind global warming/climate change recently. As a result, I have been wondering why the famous hockey stick graph, which shows a steep increase in temperature over the past few of decades, is still being used to demonstrate global warming, since scientific evidence does not seem to back it up. Finally, I came across an explanation. As stated by the author, "The story is a remarkable indictment of the corruption and cynicism that is rife among climate scientists." I highly recommend taking the time to read the whole post.
