Global Temperatures Likely To Exceed Key Limit For First Time

With October's initial temperature data in, 2024 will rank as the first calendar year in modern record-keeping in which global average surface temperatures exceed the Paris Agreement's aspirational 1.5C guardrail.

Holding warming to that target is viewed as necessary for small island states and other extremely vulnerable nations to avoid being wiped out by sea level rise, drought and other threats. Copernicus Climate Change Service reported early Thursday that the year is headed for a temperature anomaly of more than 1.55C (2.79F) above preindustrial levels.
