Ten “you must be kidding” weather and climate facts of 2023

By Bob Henson and Jeff Masters 26 December 2023 (Yale Climate Connections) – The drumbeat of record weather and climate phenomena — hottest, wettest, fieriest, fiercest, and so on — can sometimes fade into the background, like the repetitive backdrop to a mournful dirge. Then there are those sharp moments, like a cymbal crash, when […]

Petrostates planning huge expansion of fossil fuels, says UN report – “These plans throw humanity’s future into question. Governments must stop saying one thing and doing another.”

By Damian Carrington 8 November 2023 (The Guardian) – The world’s fossil fuel producers are planning expansions that would blow the planet’s carbon budget twice over, a UN report has found. Experts called the plans “insanity” which “throw humanity’s future into question”. The energy plans of the petrostates contradicted their climate policies and pledges, the report said. […]

NOAA reports 2023 hottest year on record, so far – “We will look back at 2023 and think of it as: remember that year that wasn’t so bad?”

By Lauren Sommer 28 December 2023 (NPR) – As 2023 draws to a close, it’s going out on top. “It’s looking virtually certain at this point that 2023 will be the hottest year on record,” says Zeke Hausfather, climate scientist at Berkeley Earth, a non-profit that analyzes climate trends. Though temperature records from December have […]

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 […]

Map of ensemble mean trends in ocean temperature and ice-shelf basal melting in the West Antarctic Ice Sheet (WAIS) for the Paris 2°C scenario. Temperature is averaged over the depth range 200–700 m. Trends are calculated at each point using annually averaged fields from 2006–2100. White regions indicate no significant trend. The Amundsen Sea region visualized here (latitude–longitude projection) is outlined in red in the inset map of Antarctica (polar stereographic projection). The black dashed line shows the 1,750 m depth contour of the continental shelf break and the blue dashed line outlines the continental shelf region used for analysis. Labels denote ice shelves (G, Getz; D, Dotson; Cr, Crosson; T, Thwaites; P, Pine Island; Co, Cosgrove; A, Abbot). Graphic: Naughten, et al., 2023 / Nature

The climate contradiction that will sink us – “We already have a refugee crisis; I shudder to think what would happen if everyone living within two meters of sea level would be displaced.”

By Zoë Schlanger 10 November 2023 (The Atlantic) – You’d be forgiven for thinking that the fight against climate change is finally going well. The clean-energy revolution is well under way and exceeding expectations. Solar is set to become the cheapest form of energy in most places by 2030, and the remarkable efficiency of heat pumps is driving their own uptake […]

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 […]

Factory fishing in Antarctica for krill targets the cornerstone of a fragile ecosystem – “What’s coming out of the side are the remnants of the ecosystem”

By Joshua Goodman and David Keyton 13 October 2023 (AP) – The Antarctic Endeavour glides across the water’s silky surface as dozens of fin whales spray rainbows from their blowholes into a fairy tale icescape of massive glaciers. But as a patrol of environmentalists approaches the Chilean super trawler in an inflatable boat, the cruder […]

Brazil’s big cats under threat from wind farms – “Wind power is a fantastic proposal, and the northeast certainly has plenty of wind … but wind parks must also take into account what is happening here on the ground”

By Luciana Magalhaes and Samantha Pearson 17 September 2023 JUAZEIRO, Brazil – Weighing more than 100 pounds, big cats have long reigned over this hot and semi-arid region of Brazil, developing tougher paws for the scorched earth and reaching speeds of 50 miles an hour to bring down wild boar and deer. But nothing could […]

Heaviest rainfall in Beijing in at least 140 years causes more than $13 billion in economic losses – China’s Xi calls for measures to mitigate disastrous flooding amid economic slowdown

BEIJING, 17 August 2023 (AP) – Chinese leader Xi Jinping has called for measures to mitigate the effects of this year’s disastrous flooding which has left scores dead and inflicted massive damage on crops, homes and infrastructure, including in and around Beijing. At least 90 rivers have risen above warning levels and 24 have already overflowed their […]

Map showing global water stress projected to 2050. By 2050, an additional 1 billion people are expected to live with extremely high water stress, even if the world limits global temperature rise to 1.3 degrees C to 2.4 degrees C (2.3 degrees F to 4.3 degrees F) by 2100, an optimistic scenario. Global water demand is projected to increase by 20 percent to 25 percent by 2050, while the number of watersheds facing high year-to-year variability, or less predictable water supplies, is expected to increase by 19 percent.

25 countries, housing one-quarter of the population, face extremely high water stress – By 2050, an additional 1 billion people will live with extremely high water stress

By Samantha Kuzma, Liz Saccoccia, and Marlena Chertock 16 August 2023 (WRI) – New data from WRI’s Aqueduct Water Risk Atlas show that 25 countries — housing one-quarter of the global population — face extremely high water stress each year, regularly using up almost their entire available water supply. And at least 50% of the world’s population […]
