A key feature of the new IPCC report is its look into how climate change impacts are likely to be different at 1.5°C and 2°C warming above pre-industrial levels. A comparative look at heat extremes at these two warming levels is among the topics covered. The implications of these kind of projected changes – from adverse effects on our health and safety, to creating pre-conditions for large wildfires – are not difficult to envision after the devastating heat waves of 2018.

Several recent reports have pointed out that without significant, immediate action to lower global warming emissions, we are getting dangerously close to blowing past emissions levels that would lead to a 2°C or more increase in global temperatures. That may lead some to think that the 2°C benchmark is becoming increasingly irrelevant, but nothing could be further from the truth. Read more >
