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 […]

Hurricane Milton’s terrible twisters: Outbreak in Florida killed at least 5, leveled buildings – Miami National Weather Service issued a record 55 tornado warnings, beating a previous record of 49 during Category 4 Hurricane Ian in 2022

By Alex Harris 10 October 2024 (Miami Herald) – A deadly and unprecedented wave of tornadoes swirled across Florida ahead of the arrival of Category 3 Hurricane Milton, which crossed the state from Sarasota to the Space Coast Wednesday evening. A series of twisters that struck St. Lucie County left at least five dead and, […]

Our dystopian climate isn’t just about fires and floods. It’s about society fracturing.

By Bill McKibben 9 October 2024 (The Guardian) – Even as the good people of Florida’s west coast pulled the soggy mattresses from Helene out to the curb, Milton appeared on the horizon this week – a double blast of destruction from the Gulf of Mexico that’s a reminder that physics takes no time off, not even in the […]

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 […]

I wasn’t prepared to be a climate refugee – A climate advocate learns firsthand the price of climate change in our lives and calls for voters to head off future disasters – “My daughter is still having nightmares”

By Melissa Hanson 4 October 2024 (Scientific American) – I wasn’t prepared to be a climate refugee. Not after relocating my family from drought and wildfire-prone California to the “climate haven” of Asheville, N.C. But less than two months after we moved into our delightfully wooded, mild-weather community, we were forced to leave. Even before […]

Satellite view of three hurricanes simultaneously spinning over the North Atlantic Ocean, 6 October 2024. This image shows the three storms—Milton, Kirk, and Leslie—at about 12 p.m. Central Time (17:00 Universal Time). It was captured as Milton was developing in the southwestern Gulf of Mexico, about an hour before it became a hurricane.

Three hurricanes churn in an active Atlantic Ocean in October 2024 – First-known hurricane season to see three hurricanes simultaneously present in the basin after September

By Emily Cassidy 8 October 2024 (NASA Earth Observatory) – From the stable Lagrange point 1, located one million miles above Earth, NASA’s EPIC (Earth Polychromatic Imaging Camera) imager on the DSCOVR (Deep Space Climate Observatory) satellite observed an unusually active Atlantic Basin. In early October, three hurricanes simultaneously spun over the North Atlantic Ocean. This image shows the three […]

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” […]

Homeowners hit by Hurricane Helene face the grim task of rebuilding without flood insurance – “There will absolutely be people who will be financially devasted by this event”

By Sally Ho 5 October 2024 (AP) – A week after Hurricane Helene overwhelmed the Southeastern U.S., homeowners hit the hardest are grappling with how they could possibly pay for the flood damage from one of the deadliest storms to hit the mainland in recent history. The Category 4 storm that first struck Florida’s Gulf […]

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 […]
