Where are temperatures at now?
The world's average surface temperatures reached 1C above pre-industrial times in a record-hot 2015. They will rise by 3C or more by 2100 if current trends continue, many projections show.
Yet 1.5C is the target?
A 195-nation climate summit in Paris in December asked the UN's Intergovernmental Panel on Climate Change for a report in 2018 on limiting warming to just 1.5C. The IPCC began a three-day meeting in Nairobi today to consider how to do that.
