A lot of people use the term global warming, but what does that mean…
Here, an eminent scientist explains all.
The Berkeley Earth Surface Temperature project was created to make the best possible estimate of global temperature change using as complete a record of measurements as possible and by applying novel methods for the estimation and elimination of systematic biases. It was organized under the auspices of Novim, a non-profit public interest group. Our approach builds on the prior work of the groups at NOAA, NASA, and in the UK (Hadley Center – Climate Research Unit, or HadCRU).
Berkeley Earth has assembled 1.6 billion temperature measurements, and will soon make these publicly available in a relatively easy to use format
The difficult issues for understanding global warming are
