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.

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. 

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. 

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.

Pulling together experts on hydrogen from 12 institutions throughout Europe, HYway, a new research project funded by the European Union sets out to provide an understanding of the climate and environmental risks and co-benefits of a hydrogen economy – and to advise on options for addressing those risks. 

The role of solar power (PV) as the best option for meeting the electricity access gap in Africa is underestimated. Carbon pricing and system reliability impacts on pathways to universal electricity access, according to a new study.

The use of alternative fuels could be one way for the aviation sector to reduce its emissions. A new study of fuel use in domestic flights in Norway shows some mitigation potential for alternative fuels, but warns that these alternatives are neither emission-free nor climate-neutral.

According to a new report by the Global Carbon Project, emissions of nitrous oxide – a greenhouse gas about 300 times more potent than carbon dioxide – continued unabated between 1980 and 2020.

CICERO’s natural science research is commended for its excellent scientific outputs and policy-relevant research at the international level in the evaluation of natural sciences in Norway (EVALNAT 2022-2023), coordinated by the Research Council of Norway.
