The Intergovernmental Panel on Climate Change (IPCC) has renewed its calls to the international community for taking urgent actions to limit the increase of global temperatures by 2° C vis-à-vis pre-industrial age levels.
In a report released in Berlin, IPCC experts stressed that preventing global warming necessitates urgent actions which consist of cutting greenhouse gas emissions by 40 to 70% before 2050.
IPCC experts also warned that should no significant actions be made in limiting greenhouse gas emissions, global temperatures are likely to rise by 3.7° to 4.8° C around 2100.
Greenhouse gas emissions have experienced a significant increase since the beginning of the industrial age in the mid-18th century. Most experts agree that the rise in global temperatures since this period is directly related to these emissions. Today, China and the United States remain the biggest polluters and are respectively responsible of 16.4% and 15.7% of global greenhouse gas emissions.
