According to the intergovernmental panel on climate change, a dark flag stands for our climate. On Sunday 2 November, the synthesis its the fifth report fell after the report of 1990, 1995, 2001, and 2007 :

“Warming of the climate system is unequivocal and, since 1950, many of the observed changes are unprecedented for decades or millennia. The atmosphere and the oceans have warmed, snow cover and ice has decreased, the sea level rose and the concentrations of greenhouse gases have increased. ” states the 5th IPCC report.

Five numbers are to keep in mind:

95%    is the degree of certainty that the human activity is the main cause of global warming.

4,8%   the increase in average surface temperature of the planet could reach 4.8 ° C

98cm  Sea level in 2100 compared with the period 1986-2005 could amount to almost a meter

54%    Annual emissions of anthropogenic CO2 over the period 2002 to 2011 were 54% above the 1990 level

70%   It is the need to reduce global emissions of greenhouse gases

Kyoto Protocol, entered into force in 2005, provides a 5% reduction in greenhouse gas emissions by 2012. The goal is far from being achieved globally.
