On our current trajectory, as of 2020, we are on track to reach a rise of up to 4°C by the end of the century. If we factor in countries’ pledges to cut emissions under the Paris Agreement – which are voluntary and non-binding – global temperatures will still rise by as much as 3.3°C. These are not incremental changes. Humans have never lived on such a planet. That deadly heatwave that struck Europe in 2003? That will be a normal summer. Spain, Italy and Greece will turn into deserts, with climates more like the Sahara than the Mediterranean as we know it.
