Desdemona going dark

7 November 2024 (Desdemona Despair) – My work here is done. After more than 13,000 posts warning of the end of the Phanerozoic eon and the imminent extinction of the human species, I’m calling it quits. The first Desdemona blog post was on 14 November 2008 and was titled, Rising CO2 accelerates coral bleaching: study. […]

Prevalence of undernourishment (left axis) Number of undernourished (right axis), 2005-2023. After rising sharply from 2019 to 2021, the proportion of the world population facing hunger persisted at virtually the same level for three consecutive years, with the latest estimates indicating a global PoU of 9.1 percent in 2023. In terms of population, between about 713 and 757 million people (8.9 and 9.4 percent of the global population, respectively) were estimated to be undernourished in 2023. Considering the mid-range estimate (733 million), about 152 million more people may have faced hunger in 2023 compared to 2019. Graphic: FAO

Hunger numbers stubbornly high for three consecutive years as global crises deepen: UN report – The world has been set back 15 years, with levels of undernourishment comparable to those in 2008-2009 – 1 in 11 people worldwide faced hunger in 2023, 1 in 5 in Africa

30 September 2024 (World Bank) – Domestic food price inflation remains high in many low- and middle-income countries. Inflation higher than 5 percent is experienced in 77.3 percent of low-income countries (18.2 percentage points higher since the last Update on June 27, 2024), 54.3 percent of lower-middle-income countries (8.7 percentage points lower), 44% of upper-middle-income […]

Global biodiversity report shows “catastrophic decline” in wildlife populations – “In just my lifetime, 50 years, we’ve seen a decline of 73 percent in the average size of these wildlife populations”

By Molly McCrea 18 October 2024 (CBS News) – A shocking new report on global biodiversity is detailing what it calls “a catastrophic decline” in wildlife populations ahead of a major international conference on biodiversity. On Monday, 21 October 2024, the United Nations will convene a two-week conference in Cali, Colombia called COP16. On the agenda […]

Ocean Climate Shift Index (CSI) along the track of Helene, as it developed from disturbance to tropical storm to hurricane to major hurricane. Ocean CSI in surrounding regions are drawn from 24 September 2024, when the storm developed from a potential tropical cyclone to a tropical storm, coinciding with the highest Ocean CSI (in excess of 500) measured along its track.

Hurricane Helene was supercharged by ultra-warm water made up to 500 times more likely by global warming, study finds – “The heat that human activities are adding to the atmosphere and oceans is like steroids for hurricanes”

By Rachel Ramirez 9 October 2024 (CNN) – The exceptionally warm water of the Gulf of Mexico that supercharged deadly Helene last month was made up to 500 times more likely by human-caused climate change, which also ramped up the hurricane’s wind and rain, according to a new scientific analysis. Helene, which made landfall in Florida as […]

Hurricane Milton’s extreme rapid intensification is part of a climate-fueled trend – Among Category 4 and larger hurricanes since 2022, Milton reached Category 4 status the fastest – “This is nothing short of astronomical”

By Denise Chow 7 October 2024 (NBC News) – Hurricane Milton’s last 36 hours have been nothing short of astonishing, as it strengthened from a tropical storm to a Category 5 hurricane in just over a day. The storm’s blisteringly fast evolution is part of a trend of rapidly intensifying storms fueled by climate change. The term “rapid intensification” […]

Atmospheric and wildfire responses to soil moisture reduction in the idealized experiments using the CESM2. The values represent differences between the response of a 40% soil moisture reduction perturbation experiment in July 2045 and a control simulation: (a) soil moisture in 0–10 cm depth (units: kg/m2), (b) surface air temperature (units: °C), (c) relative humidity at 2 m (units: %), and (d) logarithm of burned area [log (burned area)] (units: km2). Time evolution over Western Siberia (65.5°N, 83.75°E): (e) soil moisture over 0–10 cm depth (units: kg/m2), (f) surface air temperature (units: °C), (g) relative humidity at 2 m (units: %), and (h) logarithm of the burned area [log (burned area)] (units: km2) (blue: control simulation, yellow: 20% soil moisture reduction perturbation experiment, and brown: 40% soil moisture reduction perturbation experiment).

Abrupt intensification of northern wildfires due to future permafrost thawing – “These climate conditions lead to rapid intensification of wildfires in western Siberia and Canada in the mid-to-end of the 21st century”

25 September 2024 (IBS Center for Climate Physics) – A study, published in the journal Nature Communications by an international team of climate scientists and permafrost experts shows that, according to new climate computer model simulations, global warming will accelerate permafrost thawing and as a result lead to an abrupt intensification of wildfires in the Subarctic and […]

Project 2025 proposes eliminating aid for families and businesses rebuilding after storms – Far-right road map would end vital disaster loan program

8 August 2024 (Center for American Progress) – In the devastating aftermath of Hurricane Debby, the Southeast is tasked with the difficult work of rebuilding homes, businesses, and lives. Initial reports indicate at least six people have died from the storm. Federal agencies play a critical role in providing swift and efficient support to these families and […]

Climate “abandonment zones” are coming to the American South – Whole counties across Florida and Central Texas could begin to see their total populations decline

By Abrahm Lustgarten 2 October 2024 (The New York Times) – When Hurricane Helene, the 420-mile-wide, slow-spinning conveyor belt of wind and water drowned part of Florida’s coastline and then barged its path northward through North Carolina last week, it destroyed more than homes and bridges. It shook people’s faith in the safety of living […]

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 […]
