The human role in our ‘angry’ hot summer
Today we released a study that shows quantitatively that anthropogenic climate change substantially increased the likelihood of the record-breaking Australian summer of 2013. Indeed, human influences on the climate system increased the chances of our record hot, “angry” summer by more than five times.
Average temperatures across the globe are now 0.8°C warmer than a century ago. This shift in the average climate can lead to substantial changes in the frequency and severity of extreme climate events.
Globally, many of the record-breaking heatwaves and extreme summer temperatures occurring elsewhere have been linked to anthropogenic influences. Our latest analysis of the 2013 extreme Australian summer also demonstrates a strong human influence on the record temperatures.
