"With an annual summit next month, the United Nations assessed progress on countries’ past emissions commitments. Severe disruption would be hard to avoid on the current trajectory."
"Countries around the world are failing to live up to their commitments to fight climate change, pointing Earth toward a future marked by more intense flooding, wildfires, drought, heat waves and species extinction, according to a report issued Wednesday by the United Nations.
Just 26 of 193 countries that agreed last year to step up their climate actions have followed through with more ambitious plans. The world’s top two polluters, China and the United States, have taken some action but have not pledged more this year, and climate negotiations between the two have been frozen for months.
Without drastic reductions in greenhouse gas emissions, the report said, the planet is on track to warm by an average of 2.1 to 2.9 degrees Celsius, compared with preindustrial levels, by 2100."
