Below is a map of all of the extreme weather events of 2016 that were found to be at least in part, caused by climate change. The emerging field of Attribution Science compares the likelihood of extreme events happening in our world to a world without climate change. By measuring the difference in the likelihood of these events occurring, we can get a sense of whether climate change was responsible.

A study found that the global average temperature, which set a record high in 2016, would not have been possible without anthropogenic climate change. Humans have changed the climate. This is the proof
