June Was Earth’s 13th Straight Record-Hot Month | Weather.com

June was Earth’s hottest on record, topping the mark just set in 2023 and extending the stretch of record-hot months to over a year, according to data from the European Copernicus Climate Change Service (C3S).

Record-setting stretch of global warmth reaches 13 months: In the report, C3S said that June’s globally averaged temperature was 1.21 degrees Fahrenheit (0.67 degrees Celsius) above the 1991-2020 average, and about 0.25 degrees Fahrenheit (0.14 degrees Celsius) warmer than June 2023, the previous warmest June in their dataset.

Globally averaged temperature data is synthesized from measurements taken by weather stations, ships, aircraft and satellites.

Global temperatures have been above a critical pre-industrial temperature benchmark for a year now: June was also the 12th straight month to have its average temperature reach or exceed the threshold of 2.7 degrees Fahrenheit (1.5 degrees Celsius) above the pre-industrial average (1850-1900), based on the CS3 dataset.

T​he World Meteorological Organization (WMO) said in a press release Monday that under the Paris Agreement, nations agreed to keep the long-term global average surface temperature well below the threshold of 3.6 degrees Fahrenheit (2 degrees Celsius) above the pre-industrial average. The goal by the end of the century is to pursue efforts to limit that to 2.7 degrees Fahrenheit (1.5 degrees Celsius) above the pre-industrial average.

“The scientific community has repeatedly warned that warming of more than 1.5 degrees Celsius risks unleashing far more severe climate change impacts and extreme weather and every fraction of a degree of warming matters,” the WMO said.

June’s notables: Europe tied its second-warmest June, according to CS3. The continental U.S. also had its second-hottest June, a report from NOAA said on Tuesday.

T​here were a few pockets that had a cooler-than-average June, as shown in the blue shadings on the map at the top of this article, but most areas of the world were at least somewhat above average.

Will 2​024 top 2023 for Earth’s warmest year? N​OAA’s May climate summary said it was virtually certain 2024 would rank in the top 10 warmest years.

T​he chance this year ranks as the hottest on record was about 50%, according to that report.
