Global carbon emissions look likely to increase this year, putting at risk the hope of meeting the world's agreement to slow global warming. under the Paris Agreement

A heat wave can be lethal – and researchers have now counted the ways they can kill. Humans may have only themselves to blame.

It may sound fanciful, but researchers say a world running on 100% renewable electricity is attainable by mid-century, or even earlier.

Greenhouse gas emissions caused by urban households’ purchases of goods and services from beyond city limits are much bigger than previously thought.

The world can feed many millions of extra mouths by altering crops to make the most of local conditions, scientists say.

The 2017 UN climate summit may not hit the headlines as some of its predecessors have done, but it can speed up global action.

Protecting the world’s forests could achieve a quarter of the greenhouse gas emissions cuts needed to meet the 1.5°C Paris target, scientists say.

Rethinking land use - the way we exploit, manage and neglect the land - could achieve  about a third of the carbon cuts needed in the next decade.
