The political tipping point is coming. The falling costs of renewables are driving a political tipping point where politicians move from expensive support for renewables to embrace the sector and to tax fossil fuel externalities.

The Climate Action Tracker (CAT) estimate of the total warming of the aggregate effect of Paris Agreement commitments and of real-world policy shows little change. If all governments achieved their Paris Agreement commitments the world will likely warm 3.0°C—twice the 1.5°C limit they agreed in Paris.
