3. Evidence for climate change

Abstract

‘Evidence for climate change’ presents the scientific evidence that anthropogenic climate change is already happening and considers changes in global temperature, precipitation, sea level, and extreme weather events (heatwaves, droughts, floods, storms, and wildfires). The latest IPCC report states that it is virtually certain that anthropogenic climate change has caused increases in the frequency and severity of hot extremes and decreases in cold extremes on most continents. Climate change is also the main cause of the intensification of heavy precipitation observed over continental regions, often resulting in flooding. Moreover, human climate change has played a role in shaping the global distribution and intensity of tropical cyclones/typhoons and hurricanes. What do the climate change deniers say and why they are wrong?
