World leaders are gathering in Glasgow, U.K., for the highly anticipated COP26 climate summit.

Delegates are being asked to accelerate action on climate change and commit to more ambitious cuts in their countries’ emissions, all in an effort to limit global temperature rises.

08:46 am: World leaders must get real about climate change at COP26, UK’s Johnson says
Britain’s Johnson warns that in a world where warming hits 4 degrees Celsius, whole cities — such as Miami, Alexandria and Shanghai — will be “lost beneath the waves.”

“If we don’t get serious about climate change today, it will be too late for our children to do so tomorrow,” he tells the COP26 summit.

“The anger and impatience of the world will be uncontainable unless we make COP26 the moment when we get real about climate change. And we can get real on coal, cars, cash and trees. We have the technology to deactivate that ticking doomsday device.”
