Human activity is changing the climate in unprecedented and sometimes irreversible ways, a major UN scientific report has said. The landmark study warns of increasingly extreme heatwaves, droughts and flooding, and a key temperature limit being broken in just over a decade. The report "is a code red for humanity", says the UN chief.

More than 100 developing countries have set out their key negotiating demands ahead of the COP26 climate meeting in Glasgow.

There's likely to be a significant increase in the number of lawsuits brought against fossil fuel companies in the coming years, say researchers. Their new study finds that to date, lawyers have failed to use the most up-to-date scientific evidence on the cause of rising temperatures. As a result, there have been few successful claims for compensation. That could change, as evidence linking specific weather events to carbon emissions increases.
