When it comes to climate change and net zero, it’s always wild to me that naked disinformation and climate denial works so well.

Peak shaving.
Preprint out today in ESDD.
SRM's biggest risk is us.
'Peak-shaving' is a best-case scenario, with strong governance and international cooperation.
We propose a framework for messier geoengineering futures, which look more like, you know, the news. /1

Maps of temperature anomalies for each year. The progression to warmer, redder colours is evident over virtually the entire planet.
This 'small multiples' #dataviz approach is effective to show that nowhere is escaping from the warming due to us burning fossil fuels.

It's a myth that Net Zero will cost us. What will *really* cost us is climate heating.
Heatwaves cost lives, floods and storms cost millions in property damage, wildfires and droughts cost our environment.
Cost of climate inaction >> cost of action.
Acting now = an investment in the future.

I think over the coming years, it will be important to state true and important things regularly. Climate change is real, it’s important and it’s caused by human activity. Most of its impacts on humans will be negative. It can be tackled by us too.

NEW: Coal-fired power generation fell in both China and India in 2025, for the first time since 1973. The drop came after record clean energy additions in both countries, and was the first time that clean energy was a major driver of falling coal power use.
