2084 = +4°C
At the current rate of warming, we are on track to reach +4°C by 2084. In just 50 years, we could be living on a planet that is largely uninhabitable.
Let that sink in.
According to the University of Exeter, 3°C of warming could kill 50% of the global population. And yet we are heading for 4°C, if we continue business as usual—expanding fossil fuels, building more, consuming more, and denying what’s right in front of us.
Anyone still claiming “we shouldn’t be alarmist” should no longer be taken seriously in public discourse. If you’re not alarmed, you haven’t understood the science—or the stakes.
This projection is based on Leon Simons’ extrapolation of data from “Global Warming has Accelerated Significantly” (Grant Foster & Stefan Rahmstorf, 2025 preprint), extending the trends to a terrifying +4°C future.
We are not talking about a distant future.
We are talking about ensuring an uninhabitable earth within our lifetimes.
What are we doing?
Thank to the amazing Leon Simons for making this.
