The world surpassed the 2°C warming limit in record time.

For the first time, the global average temperature on November 17th was 2 degrees Celsius warmer than pre-industrial levels, according to preliminary data shared on X by Samantha Burgess, deputy director of the European-based Copernicus Climate Change Service.

This threshold has only been temporarily crossed and does not mean the world is in a state of permanent warming above 2 degrees. “Our best estimate is that this is the first day global temperatures are more than 2°C above the 1850-1900 (or pre-industrial) level, at 2.06°C,” wrote Ms. Burgess.

Ms. Burgess stated in her post that global temperatures on November 17th averaged 1.17 degrees Celsius higher than the average for the 1991-2020 period, making it the warmest November 17th on record. However, compared to pre-industrial levels, before humans began burning fossil fuels on a large scale and altering the Earth's natural climate, temperatures were already 2.06 degrees Celsius warmer.

The exceeding of 2 degrees Celsius on November 17th occurred two weeks before the start of the United Nations' COP28 climate conference in Dubai, where countries will assess their progress toward their commitments under the Paris Climate Agreement to limit global warming to 2 degrees above pre-industrial levels.

Ms. Burgess told CNN that a single day with temperatures rising above 2 degrees "doesn't mean the Paris Agreement has been violated," "but we can expect more days exceeding that mark in the coming months and years."

Copernicus's data is preliminary and will take weeks to be confirmed by actual observations.
