Scientific Background

This widget is inspired by a post by the Scientist Stefan Rahmstorf in the german Klimalounge Blog. It illustrates the correlation of observed global mean temperature anomalies with increasing CO2 and changes in the number of sun spots.

Please read the blog post for more information on the scientific background. More References:
