Global mean surface temperature anomaly, 1970-2023. The average global temperature in 2023 was 1.32°C above that during the pre-industrial baseline period of 1850 to 1900, surpassing the previous record of 1.29°C that was set from October 2015 to September 2016.

Earth had its hottest year on record in 2023 – “This is the hottest temperature that our planet has experienced in something like 125,000 years”

By Carissa Wong 10 November 2023 (Nature) – The past 12 months were the hottest on record. Some 7.3 billion people worldwide were exposed, for at least 10 days, to temperatures that were heavily influenced by global warming, with one-quarter of people facing dangerous levels of extreme heat over the past 12 months, according to a report […]

Climate-driven extreme heat may make parts of Earth too hot for humans – “If temperatures continue to rise, we will live in a world where crops are failing and millions or billions of people are trying to migrate because their native regions are uninhabitable”

By Aaron Wagner 9 October 2023 UNIVERSITY PARK, Pa. (PennState) – If global temperatures increase by 1 degree Celsius (C) or more than current levels, each year billions of people will be exposed to heat and humidity so extreme they will be unable to naturally cool themselves, according to interdisciplinary research from the Penn State […]

In Texas, water levels are so low a rarely-seen underwater cave and century-old ruins have appeared – “I haven’t seen the water this low since I moved here. It’s actually kind of sad.”

By Amanda Jackson and Zoe Sottile30 September 2023 (CNN) – Water levels are so low at Canyon Lake in Texas that an underwater cave and remnants of communities that stood more than a century ago at the site are reappearing. The lake, located in Comal County just northeast of San Antonio, is a man-made lake spanning 8,200 acres with […]

Swiss glacier watcher warns 2023 heat wave threatens severe melt again after record 2022 – “We can definitely say that we had very high melting in Switzerland and in Europe in general”

By Jamey Keaten 1 September 2023 GENEVA (AP) – A top glacier watcher has warned that a warm early summer combined with a heat wave last week may have caused severe glacier melt in Switzerland, threatening to make 2023 its second-worst year for ice loss after a record thaw last year. Matthias Huss of the GLAMOS […]

Heat dome shatters all-time U.S. records as Europe roasts – “Brutal” heat wave brings triple-digit temperatures from Chicago to New Orleans – 110 million people exposed to dangerous heat

By Andrew Freedman 24 August 2023 (Axios) – In a summer featuring countless heat domes and record-high temperatures and heat indices, the season appears to have saved the worst for last. The big picture: A sweltering, stagnant air mass is draped across the Central U.S., resulting in “dangerous,” “searing” and “brutal” heat. Meanwhile, southern Europe is also seeing another bout of […]

Climate collapse could happen fast – “For a long time, we were within the range of normal. And now we’re really not. And it has happened fast enough that people have a memory of it happening.”

By Lois Parshley 20 July 2023 (The Atlantic) – Ever since some of the earliest projections of climate change were made back in the 1970s, they have been remarkably accurate at predicting the rate at which global temperatures would rise. For decades, climate change has proceeded at roughly the expected pace, says David Armstrong McKay, a […]

Pacific island sea levels rising faster than global average, WMO says – Economic damage in Southwest Pacific due to flooding in 2022 was $8.5 billion, almost triple compared to the previous year

By Gabrielle Tétrault-Farber 17 August 2023 GENEVA (Reuters) – Sea levels in the South-West Pacific are rising faster than the global average, threatening low-lying islands while heat damages marine ecosystems, the U.N. meteorological agency said on Friday. In its State of the Climate in the South-West Pacific 2022 report, the World Meteorological Organization (WMO) said […]

How climate scientists feel about seeing their dire predictions come true – “I used to think, ‘I’m concerned for my children and grandchildren.’ Now it’s to the point where I’m concerned about myself.”

By Corinne Purtill 18 August 2023 (Los Angeles Times) – You are correct. It is, in fact, extremely unusual to be on hurricane watch in Southern California. If Hurricane Hilary continues on the trajectory forecasters are currently predicting, it will be the first tropical storm to make landfall in California since 1939, and only the second one to do […]

July 2023 sees multiple global temperature records broken – Global mean temperature temporarily exceeded the 1.5° C threshold – “The extreme weather which has affected many millions of people in July is unfortunately the harsh reality of climate change and a foretaste of the future”

8 August 2023 (C3S) – The month started with the daily global mean surface air temperature record being broken on four days in a row, from 3-6 July. All days throughout the rest of July were hotter than the previous record of 16.80°C, set on 13 August 2016, making the 29 days from 3-31 July […]
