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 […]

Humans are disrupting natural “salt cycle” on a global scale

31 October 2023 (University of Maryland) – The influx of salt in streams and rivers is an ‘existential threat,’ according to a research team led by a UMD geologist. The planet’s demand for salt comes at a cost to the environment and human health, according to a new scientific review led by University of Maryland Geology Professor Sujay Kaushal. Published […]

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 […]

Change Over Time in (a) US Life Expectancy and (b) US Life Expectancy Gap and Rank Relative to Populous Countries (Population>500000), 1950-2021. Phase 1=1950–1954; phase 2=1955–1973; phase 3=1974–1982; phase 4=1983–2009; phase 5=2010–2019; phase 6=2020–2021. Bars plot the difference in life expectancy between the United States and the populous country (population >500000) with the highest life expectancy in the given year. The country with the highest life expectancy was Norway in 1950–1962 and 1976–1977, Sweden in 1963 and 1965–1975, the Netherlands in 1964, Japan in 1978–2007, Macao in 2008–2010, and Japan in 2011–2021. The line graph plots US rank relative to other populous countries, with higher rank denoting lower US life expectancy. Source: Author’s calculations based on UN data. Graphic: Steven H.

U.S. has been falling behind on life expectancy for decades – Between 1933 and 2021, 56 countries achieved higher life expectancy than U.S. – “Americans are sicker and die earlier than people in dozens of countries”

By Olivia Trani 1 June 2023 (VCU) – When it comes to public health, the United States is at a disadvantage compared with other developed countries. Americans experience more illness, have less access to health care and pay more for health services than citizens in other high-income countries. Americans also die earlier – and have been doing so […]

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 […]

EIU Democracy Index 2022, global map by regime type. The average global index score stagnated in 2022. Despite expectations of a rebound after the lifting of pandemic-related restrictions, the score was almost unchanged, at 5.29 (on a 0-10 scale), compared with 5.28 in 2021. The positive effect of the restoration of individual freedoms was cancelled out by negative developments globally. The scores of more than half of the countries measured by the index either stagnated or declined. Western Europe was a positive outlier, being the only region whose score returned to pre-pandemic levels. Graphic: EIU

EIU Democracy Index 2022: Frontline democracy and the battle for Ukraine – “Overall the story is one of stagnation. This is a dismal result given that in 2022 the world started to move on from the pandemic-related suppression of individual liberties that persisted through 2020 and 2021”

1 February 2023 (EIU) – The Democracy Index, which began in 2006, provides a snapshot of the state of democracy worldwide in 165 independent states and two territories. This covers almost the entire population of the world and the vast majority of the world’s states (microstates are excluded). The Democracy Index is based on five […]

U.S. Health Care from a Global Perspective, 2022: Accelerating spending, worsening outcomes – “Americans are more likely to die younger, and from avoidable causes, than residents of peer countries”

By Munira Z. Gunja, Evan D. Gumas, and Reginald D. Williams II 31 January 2023 (The Commonwealth Fund) – In the previous edition of U.S. Health Care from a Global Perspective, we reported that people in the United States experience the worst health outcomes overall of any high-income nation.1 Americans are more likely to die younger, and […]

The first global decline in life expectancy since World War II poses a major threat to the economy

By Matthew Heimer and Nicolas Rapp6 December 2022 (Fortune) – COVID’s devastation shows up starkly in life expectancy data: The pandemic’s peak marked the first time since World War II that LE (as demographers call it) declined across the globe. The graphic above is based on a data set that focuses mostly on Europe, but similar […]
