On melting glaciers and science as a contact sport

This week we were inspired by Skeptical Science.com,  a site for people who are "skeptical about global warming skepticism." On February 10, Skeptical Science put some of its best scientific rebuttals to arguments commonly used by climate change deniers in a handy cheat-sheet format that you can consult from your i-Phone. Leo Hickman, over at The Guardian / Environment blog, wrote about the tempest this tactical app immediately roused in the opposing camp.
 

On Wednesday we asked Michael MacCracken, Chief Scientist for Climate Change Programs with the Climate Institute in Washington DC, to answer simple questions about the facts: Are the glaciers melting faster in the past? Do we know why? What about the sun? And why are climate change debates so heated anyway?!

MacCracken was at the World Bank on March 3 presenting the huge body of scientific evidence that has accumulated in the past few decades and the rigorous methodologies employed by scientists to understand data from various sources. He has blogged here in the past about geoengineering
