Swiss glacier melt exceeds average in 2024 after hot summer – “This will be a disaster for Swiss glaciers”

By Denis Balibouse and Cecile Mantovani 1 October 2024 ZURICH (Reuters) – Swiss glaciers melted at an above-average rate in 2024 as a blistering hot summer thawed through abundant snowfall, monitoring body GLAMOS said on Tuesday. Earlier this year, glaciologists had celebrated heavy winter and spring snow dumps in the Alps, hoping this would signal […]

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 […]

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 […]

WMO annual report highlights continuous advance of climate change – “While greenhouse gas emissions continue to rise and the climate continues to change, populations worldwide continue to be gravely impacted by extreme weather and climate events”

Geneva, 21 April 2023 (WMO) – From mountain peaks to ocean depths, climate change continued its advance in 2022, according to the annual report from the World Meteorological Organization (WMO). Droughts, floods, and heatwaves affected communities on every continent and cost many billions of dollars. Antarctic sea ice fell to its lowest extent on record […]

Regional glacier mass change and contributions to sea level rise from 2015 to 2100. Discs show global and regional projections of glacier mass remaining by 2100 relative to 2015 for global mean temperature change scenarios. Discs are scaled based on each region’s contribution to global mean sea level rise from 2015 to 2100 for the +2°C scenario by 2100 relative to preindustrial levels, and nested rings are colored by temperature change scenarios showing normalized mass remaining in 2100. Regional sea level rise contributions >1 mm SLE for the +2°C scenario are printed in the center of each disc. The horizontal bars below each disc show time series of area-averaged annual mass balance from 2015 to 2100 for +1.5°C (top bar) and +3°C (bottom bar) scenarios. The colorbar is saturated at −2.5 m w.e., but minimum annual values reach −4.2 m w.e. in Scandinavia. Graphic: Rounce, et al., 2022 / Science

Half of glaciers will be gone by 2100 even under Paris 1.5C accord, study finds

By Phoebe Weston 5 January 2023 (The Guardian) – Half the planet’s glaciers will have melted by 2100 even if humanity sticks to goals set out in the Paris climate agreement, according to research that finds the scale and impacts of glacial loss are greater than previously thought. At least half of that loss will happen […]

Hoof prints left by Camargue bulls mark a section of pasture encrusted with salt on the Raynaud ranch in Camargue, southern France, 23 September 2022. 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.

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 […]
