Norway's leading institute for climate research

Global warming has accelerated since 2010. A new CICERO-led study shows that unmasking of greenhouse-gas-driven warming due to a substantial cleanup in air pollution over East Asia can explain it.

Climate models that give a low warming from increases in greenhouse gases do not match satellite measurements. Future warming will likely be worse than thought unless society acts, according to a new study published in Science. 

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.
