At 3C of warming, scientists predict the world could pass several catastrophic points of no return, from the runaway melting of ice sheets to the Amazon (NASDAQ:) rainforest drying out.
“Present trends are racing our planet down a dead-end 3C temperature rise,” said U.N. Secretary-General Antonio Guterres. “The emissions gap is more like an emissions canyon.”
World leaders will soon meet in Dubai for the annual U.N. climate summit COP28 with the aim of keeping the Paris Agreement warming target of 1.5C alive.
But the new U.N. report does…
