Alps – Desdemona Despair

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 […]

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 […]

As soil salt levels rise due to drought and reduced river flow from the Rhone River, the land traditionally used by bull breeders like the Raynaud family is becoming more and more difficult to maintain as a suitable pace to raise animals.

In southern France, drought, rising seas threaten traditions – “The sea level rises on our coast and takes more and more of our land”

By Daniel Cole 30 October 2022 SAINTES-MARIE DE LA MER, France (AP) – In a makeshift arena in the French coastal village Aigues-Mortes, young men in dazzling collared shirts come face-to-face with a raging bull. Surrounded by the city’s medieval walls, the men dodge and duck the animal’s charges while spectators let out collective gasps. […]

Kilimanjaro’s and Africa’s last glaciers to go by 2050, says UN – “What is quite unprecedented in the historical record is how quickly this is happening”

By Patrick Hughes 3 November 2022 (BBC News) – Glaciers across the globe – including the last ones in Africa – will be unavoidably lost by 2050 due to climate change, the UN says in a report [UNESCO finds that some iconic World Heritage glaciers will disappear by 2050 –Des]. Glaciers in a third of […]

State of the Global Climate 2022: Sea level rise accelerates, European glacier melt shatters records, extreme weather causes devastation – “What climate scientists have warned about for decades is upon us”

By Seth Borenstein 6 November 2022 SHARM EL-SHEIKH, Egypt (AP) – Earth’s warming weather and rising seas are getting worse and doing so faster than before, the World Meteorological Organization warned Sunday in a somber note as world leaders started gathering for international climate negotiations.

Projected changes in surface temperatures in the Alps, 2021-2050. The Alpine region experiences a higher temperature rise than peri-Alpine areas or at least that the temperature changes start earlier. Large parts of Bavaria, Lombardy and other regions depend on ecosystem services provided by the Alps. Decreasing quantities of water and a reduced reliability of supply will become major issues in the coming decades. This affects not only the drinking water supply but also agriculture, energy production, and industrial cooling demand. Graphic: FAU

Water woes loom in the Alps amid climate change – “Reduced quantities of water and limited reliability of water supply will be a major issue in the coming decades”

By Jamey Keaten 27 October 2022 BRIG, Switzerland (AP) – A battle is brewing around Europe’s rooftop over the planet’s most precious resource. The crystal-clear waters issuing from the Alps could become increasingly contested as the effects of climate change and glacier melt become more apparent. Italy wants them for crop irrigation in the spring […]

Percent change in ice volume for Swiss glaciers, 2001-2022. Melt rates in 2022 far exceeded the previous records from the hot summer of 2003. Glaciers in Switzerland lost around 3 cubic kilometres of ice in 2022, more than 6 percent of the remaining volume. By way of comparison, up to now, years with an ice loss of 2 percent have been described as “extreme”. The loss was particularly dramatic for small glaciers. Graphic: M.

2022 heat wave drove unprecedented melt of Swiss glaciers – “2022 was a disastrous year for Swiss glaciers: all ice melt records were smashed by the great dearth of snow in winter and continuous heat waves in summer”

By Jamey Keaten 28 September 2022 GENEVA (AP) – Switzerland’s glaciers are melting like never before, an academic study released Wednesday found, with their ice volume declining by 6% this year amid rising concerns about global warming and a summer heat wave that swept across Europe. The Swiss Academy of Sciences reported that the shrinkage […]

World’s supply of fresh water in trouble as mountain ice vanishes – 1.9 billion people at risk from mountain water shortages – “The most important water towers are also among the most vulnerable”

By Alejandra Borunda 9 December 2019 (National Geographic) – High in the Himalaya, near the base of the Gangotri glacier, water burbles along a narrow river. Pebbles, carried in the small river’s flow, pling as they carom downstream. This water will flow thousands of miles, eventually feeding people, farms, and the natural world on the vast, […]

By Denis Balibouse 25 November 2019 THE FURKA PASS, Switzerland (Reuters) – On the hairpin bend of a Swiss mountain pass, a Victorian-era hotel built for tourists to admire the Rhone Glacier has been abandoned now that the ice has retreated nearly 2 km (1.2 miles) uphill. Where mighty glaciers once spilled into Swiss valleys […]
