Norway's leading institute for climate research

Today, there are separate early warning systems for extreme heat and air pollution in India. A new project will assess exposure and health impacts from concurrent extreme heat and air pollution in Delhi and Kolkata and work to make a joint early warning system for both these challenges.

Would local decision-makers be more likely to act on climate change if they knew the maximum amount of co₂ that could be emitted to avoid critical climate risk in their community? Yes, argue researchers who propose a new approach that links climate risk thresholds at local level to emission pathways.

While emissions have grown and climate targets become more ambitious over the last decade, the investments needed to limit global warming to below 1.5-2°C have not increased, thanks to faster-than-expected reduction in costs of clean technologies such as solar, wind and battery storage. This analysis was published in Nature Climate Change. 

Hydrogen as an alternative fuel has long been a topic of discussion. Now, a new research project has examined hydrogen leaks—and their potential consequences for the climate.

How are net zero emissions defined? It matters. It is the difference between either halting or continuing global warming, writes senior researcher Glen Peters in this blog about a new study published in Nature. 

Global fossil co₂ emissions are expected to grow 0.8% in 2024, despite predictions of peak emissions. The positive progress in many countries and clean technologies is offset by persistent fossil fuel use.
