Temperature changes

Global warming must peak below 2°C then return under 1.5°C as quickly as possible to limit the risk of dangerous “tipping points”, experts say.

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.

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.

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. 

Heat-related deaths and diseases are a major concern in Europe amid increasing extended periods of extreme heat. This study proposes a novel way of quantifying and projecting future vulnerability to heat stress in different areas of a city, providing local decision-makers with knowledge for designing more effective adaptation strategies to minimize health impacts of heat stress.

The dangerous impacts of aerosol changes on vulnerable regions should have been a priority at COP27 after climate policymakers agreed a breakthrough deal to support these parts of the world, scientists have claimed.

Europe is warming faster than the global average, and has seen a dramatic increase in the number of heatwaves over the past 40 years. This trend will likely continue, even with major reductions in greenhouse gas emissions.

In a recent study published in Nature Communications, international scientists have taken on a persistent problem in climate science: near-term climate evolution.

Climate change is increasingly impacting people's health all over the world. As heatwaves become hotter and more frequent, the most vulnerable suffer the most.
