The past three years have been the world’s hottest on record. In 2025, Earth was 1.44°C warmer than the long-term average, perilously close to breaching the Paris Agreement goal of 1.5°C.

This warming is fuelling Australia’s current record-breaking heatwave. Other consequences are visible globally, from Iran’s crippling drought to catastrophic wildfires and unprecedented floods in the United States to deadly cyclones hitting southern Asia.

We know what to do to tackle the climate crisis: replace fossil fuels with clean energy technologies such as solar, wind, electric vehicles and batteries. We are well on our way. Globally, the power produced by renewables overtook coal last year.

Petrostates such as Saudi Arabia and the US have made trillions from oil and gas. Now they are fighting a rearguard action to prolong fossil fuels. The US is pushing European nations to buy its gas, for instance.

Dozens of countries will meet in Colombia in April to fast-track the transition. The road ahead is bumpy. But the end of fossil fuels may finally be coming into view.

In 2025, he increased subsidies for fossil fuel producers,........
