Global warming – the bottom line

It’s official – Earth is warming, and we have a pretty good idea of by how much and how fast it is warming. The figure is 0.9 ± 0.04 degrees Celsius since the mid-1950’s, according to the Berkeley Earth Surface Temperature project, which last month published a comprehensive review based on 1.6 billion records from 15 pre-existing archives. Today, Nature Climate Change publishes an interview with project director Richard Muller.

Read the interview with Muller for yourselves, if you have access to the journal, and delve into the publicly available data and analysis programs if so inclined. The Berkeley Earth Surface Temperature project shows how climate science is and should be done.
