Annual global mean surface temperature anomalies relative to 1850–1900. Global mean near-surface temperature in 2023 was 1.45 ± 0.12 °C above the 1850–1900 average. The analysis is based on a synthesis of six global temperature datasets. 2023 was the warmest year in the 174-year instrumental record in each of the six datasets. The past nine years – from 2015 to 2023 – were the nine warmest years on record. The two previous warmest years were 2016, with an anomaly of 1.29 ± 0.12 °C, and 2020, with an anomaly of 1.27 ± 0.13 °C. Globally, every month from June to December was record warm for the respective month. September 2023 was particularly noteworthy, surpassing the previous global record for September by a wide margin (0.46 °C–0.54 °C) in all datasets. The second-highest margin by which a September record was broken in the past 60 years (the period covered by all datasets) was substantially smaller, at 0.03 °C–0.17 °C in 1983. July is typically the warmest month of the year globally, and thus July 2023 became the warmest month on record. The long-term increase in global temperature is due to increased concentrations of greenhouse gases in the atmosphere. The shift from La Niña, which lasted from mid-2020 to early 2023, to fully developed El Niño conditions by September 2023 likely explains some of the rise in temperature from 2022 to 2023. However, some areas of unusual warming, such as the North-East Atlantic do not correspond to typical patterns of warming or cooling associated with El Niño. Other factors, which are still being investigated, may also have contributed to the exceptional warming from 2022 to 2023, which is unlikely to be due to internal variability alone. Graphic: WMO

WMO: Climate change indicators reached record levels in 2023 – “Sirens are blaring across all major indicators. Some records aren’t just chart-topping, they’re chart-busting. And changes are speeding-up.”

19 March 2024 (WMO) – A new report from the World Meteorological Organization (WMO) shows that records were once again broken, and in some cases smashed, for greenhouse gas levels, surface temperatures, ocean heat and acidification, sea level rise, Antarctic sea ice cover and glacier retreat. Heatwaves, floods, droughts, wildfires, and rapidly intensifying tropical cyclones […]

Great Lakes start 2024 with smallest amount of ice in at least 50 years – “There’s a clear trend, and ice cover in the Great Lakes is decreasing”

By Dan Rosenzweig-Ziff 2 January 2024 (The Washington Post) – The Great Lakes had the smallest amount of ice cover this New Year’s Day in at least the past 50 years and are on track to see less than the seasonal average this winter, according to government data. The decline comes during a five-decade drop […]

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 […]

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 […]

Forests are no longer our climate friends – “As extreme as this year’s wildfire emissions have been, they are just the latest escalation in a multi-decade flood of CO₂ pouring out of Canada’s ‘managed’ forests and forestry”

By David Wallace-Wells 6 September 2023 (The New York Times) – Canadian wildfires have this year burned a land area larger than 104 of the world’s 195 countries. The carbon dioxide released by them so far is estimated to be nearly 1.5 billion tons — more than twice as much as Canada releases through transportation, […]
