Long hot summer

2023 will claim the title as the warmest year ever recorded, according to the World Meteorological Organization. Its provisional State of the Global Climate report shows global temperatures are 1.4 degrees above pre-industrial levels, carbon dioxide levels are up 50% and the sea level rise from 2013-2022 is more than twice the rate recorded from 1993-2002.
