Janice Sinclaire

Climate scientist Ed Hawkins posted this GIF as a visualization of global temperatures spiraling upward from the average global temperature for the 1850 to 1900 time frame. The graphic has gone viral on social media. Hawkins is editor of the Climate Lab Book, an “experiment” in open-source climate science. The goal of the blog is to promote collaboration through open scientific discussion on climate science, with posts written by climate scientists but open for anyone to see and comment on. Hawkins is with the University of Reading in the UK and an author for the Intergovernmental Panel on Climate Change's Fifth Assessment Report.
