Three years left to limit warming to 1.5C, leading scientists warn

The Earth could be doomed to breach the symbolic 1.5C warming limit in as little as three years at current levels of carbon dioxide emissions.
That's the stark warning from more than 60 of the world's leading climate scientists in the most up-to-date assessment of the state of global warming.
Nearly 200 countries agreed to try to limit global temperature rises to 1.5C above levels of the late 1800s in a landmark agreement in 2015, with the aim of avoiding some of the worst impacts of climate change.
But countries have continued to burn record amounts of coal, oil and gas and chop down carbon-rich forests - leaving that international goal in peril.
Climate change has already worsened many weather extremes - such as the UK's 40C heat in July 2022 - and has rapidly raised global sea levels, threatening coastal communities.
"Things are all moving in the wrong direction," said lead author Prof Piers Forster, director of the Priestley Centre for Climate Futures at the University of Leeds.
"We're seeing some unprecedented changes and we're also seeing the heating of the Earth and sea-level rise accelerating as well."
These changes "have been predicted for some time and we can directly place them back to the very high level of emissions", he added.
