2025 was confirmed as the hottest year in recorded human history, continuing a streak that has now run for over a decade. The science is not the contested part anymore. What deserves more attention is the gap between what is being done and what the models say is necessary.

Global renewable energy deployment is genuinely accelerating. Solar installation in particular has beaten nearly every projection made ten years ago — costs have fallen faster and adoption has spread wider than analysts expected. This is good news and it is real. The problem is that it is happening alongside continued fossil fuel use rather than replacing it at the rate required to hit agreed temperature targets.
