Global Food Supplies (Crops, Livestock, Fisheries) Are Pushed to Brink by Extreme Heat: New UN Study
The United Nations (UN) Food and Agricultural Organization (FAO) has combined with the World Meteorological Organization (WMO) to produce a new report describing in detail how extreme heat waves are putting global food production on the brink of failure.
Food production categories looked at include crops, livestock, food producing trees (fruits, nuts), fisheries and aquaculture, as well as the farming and fishing and associated industries themselves.
This well written report is extremely important to be aware of, since, as far as I know, we all have to eat to survive.

EXTREME HEAT IMPACTS ON AGRIFOOD SYSTEMS
Extreme heat events currently threaten the livelihoods and health of over a billion people, with the prospect for damage to livestock herds and crop yields set to soar even higher, according to a new report co-authored by the Food and Agriculture Organization of the United Nations (FAO).

New 108 page UN report released Wednesday April 22nd titled:
EXTREME HEAT AND AGRICULTURE
FAO–WMO joint report
The “Extreme heat and agriculture” report shows that the frequency, intensity and duration of extreme heat events have risen sharply over the past half century. Agricultural workers and agrifood systems are on the frontlines, absorbing the greatest impacts.

Title: Deadly heat stress conditions are already occurring
Link: nature.com/articles/s41467-026-70485-1
Abstract
Heat stress limits for human survivability have been previously defined by a 6-hour exposure to a wet-bulb temperature of 35 oC. However, the recently developed physiology-based HEAT-Lim model demonstrates that environmental heat stress thresholds may be cooler and drier than previously
thought. We employ HEAT-Lim to determine whether non-survivable thresholds were surpassed during six historical events where conditions were climatologically extreme and/or high heat-related mortality was reported. Our results show that non-survivable conditions are occurring
during present-day heat events, all of which are below 35oC wet-bulb temperature. Of concern is regular exceedances of deadly thresholds for older people directly exposed across all events. Moreover, extremely hot yet dry conditions are found to be just as deadly as hot and humid conditions. For future climatological assessments, we emphasize the importance of employing increasingly accurate physiology-derived methods to assess the risk of potentially deadly heat stress.
