Current global warming is caused by the accumulation in the atmosphere of greenhouse gases produced by the combustion of oil, gas and coal. Paleoclimatic studies allow us to compare this change with natural climatic variations of the past. They show that current warming is rapid and significant. Climatologists are also modeling the climate of the future, for the 21st century and beyond. The results, compiled by the Intergovernmental Panel on Climate Change (IPCC), show that limiting global warming to an acceptable level for our societies requires a sharp reduction in greenhouse gas emissions. The links between climate change, the frequency and amplitude of extreme events (heatwaves, storms, etc.), sea levels, etc., are key issues for assessing risks and possible adaptations.
