National Observatory on the Effect of Global Warming (ONERC, after its French name) says temperatures in France could rise by nine degrees Celsius by the end of this century exceeding the worst case scenario set forth by the IPCC (Intergovernmental Panel for Climate Change).

A June 5, 2007 study published by Geophysical Research Letters states that mediterranean countries will face a 200-500% rise in the number of hot days that are deemed dangerous. France would experience the greatest increase in extreme high-temperature days.

15,000 french died in 2003 due to a heat wave. This is expected to become the norm as greenhouse gas concentrations increase according to Noah S. Diffenbaugh of Purdue University.
