The widest-ever global coral crisis will hit within weeks, scientists say – “Now we’re at the point where we’re in the disaster movie”

By Catrin Einhorn 15 April 2024 (The New York Times) – The world’s coral reefs are in the throes of a global bleaching event caused by extraordinary ocean temperatures, the National Oceanic and Atmospheric Administration and international partners announced Monday. It is the fourth such global event on record and is expected to affect more […]

Groundwater resources are drying up across the globe – “Climate variability and change can impact water supplies underground as well as above-ground”

By Matthew Rozsa 24 January 2024 (Salon) – Humans rely on groundwater for many things, but especially our food. Roughly 30 percent of all the planet’s available freshwater comes from groundwater, or water that is found underground in the spaces between rocks, soil and sand. It is primarily used for agriculture and billions of humans are dependent […]

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 […]

Earth’s warmest March is 10th straight record month, NOAA and NASA find

By Jonathan Erdman 12 April 2024 (Weather.com) – March was Earth’s warmest on record, according to data from three separate agencies, the latest month in a stretch of heat records since the planet’s hottest year in 2023. Another month, another record In a report released Friday, NOAA found March’s globally average temperature was 2.43 degrees Fahrenheit above […]

New study calculates climate change’s economic impact will hit $38 trillion per year by 2049 – World economy already committed to income reduction of 19 percent – World’s poorest countries will suffer 61 percent bigger income loss than the richest ones

By Seth Borenstein 17 April 2024 (AP) – Climate change will reduce future global income by about 19% in the next 25 years compared to a fictional world that’s not warming, with the poorest areas and those least responsible for heating the atmosphere taking the biggest monetary hit, a new study said. Climate change’s economic […]

Cholera cases soar globally amid shortage of vaccines – “The unprecedented rate of cases and deaths is terrifying, and utterly overwhelming the health systems of these countries”

By Weronika Strzyżyńska 12 January 2024 (The Guardian) – Cholera cases soared last year, according to preliminary data from the World Health Organization, which recorded 4,000 cholera deaths and 667,000 cases globally. The numbers surpassed that of 2022, and the WHO has classified the global resurgence of cholera as a grade 3 emergency, its highest internal health […]

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. […]
