Europe in particular is experiencing a fairly high temperature elevation. What about our country? France has already won 1 ° C, a half times the global warming. According to the first report of ONERC (1), if the trend continues, the temperature in France could rise 3 ° C by a century or even 9 ° C in the assumption of the worst a global warming of 6 ° C. Moreover, the warming will be branded in the summer, causing heat waves more frequent.
