These heat maps from NASA help visualise the story of global warming from 1930 to 2021. Find out how much hotter earth is today than when you were born.

2. Could hydrogen-fuelled flights be a reality by 2035?

To achieve net-zero goals, aviation industry leaders are turning to alternative fuels, such as hydrogen, to reduce the industry's environmental footprint.

A new report by the World Economic Forum and the University of Cambridge’s Aviation Impact Accelerator explores how aviation can achieve a true zero climate impact.

While researchers urge the world to cut greenhouse-gas emissions, cities must also prepare to deal with the heat. From adapting key infrastructure such as railways to adding things like robust weather warning systems, the world needs to take action.

Discover how heatwaves are impacting life around the globe.

4. These eco-friendly foods are helping tackle climate change

The global food system generates roughly one-third of global greenhouse gas emissions. So, agriculture and food production systems are central to efforts to cut global emissions.
