A new report warns that the current strong El Niño event, which is pushing global temperatures unusually high, could contribute to nearly half a million deaths over the next six months. The report describes the extreme heat as a preview of conditions expected to become the norm within a few decades.
Climate scientists tracking 14 forecasting models report that central Pacific sea surface temperatures are running about 2.9°C above the 30-year average, more than 1°C hotter than at the same point in the record 1997 and 2015 El Niño events. Models now give a greater than 90% probability that this year's El Niño will exceed every event recorded since the 1870s, raising fears of severe drought, flooding, wildfires and coral bleaching worldwide.
A tech newsletter roundup covers preparations for an extreme El Niño event, new developments in jet-powered drone warfare, the emergence of credit cards designed for AI agents to make purchases, and a GLP-1 drug manufacturer partnering with Anthropic's Claude to accelerate medicine development.
The US Climate Prediction Center says above-normal temperatures will persist across much of the country through late September, driven by a strong El Niño pattern and an atmospheric ridge trapping warm air. Some regions, including the Upper Midwest and Deep South, could see readings 5 to 10 degrees Fahrenheit above normal, extending a summer that already set numerous heat records nationwide.
NOAA announced on September 14 that El Niño has officially crossed the threshold to become a 'very strong event' for the Northern Hemisphere fall and winter of 2026-27, a designation known as a Super El Niño. Forecasters say this could become the strongest El Niño on record, with effects lingering into 2027 and potentially raising sea levels along California's coast by up to a foot.
Researchers warn that this year's El Niño event, combined with ongoing global warming, resembles a rare pattern last observed in the late 1990s. They caution that the interaction between these two forces could produce extreme weather events that fall outside the range of existing climate models and historical data.
The US National Science Foundation is moving to a 'portfolio-based' funding approach that blends traditional investigator-driven research with agency-directed priorities, according to an internal letter. The agency has not specified what these directed opportunities will entail, leaving staff and researchers uncertain about future funding categories.
Peru's government ended its anchovy fishing season early after warming Pacific waters pushed the fish into deeper, colder areas, illustrating the reach of this year's unusually powerful El Niño. Scientists say the event is forecast to become one of the strongest on record, and its effects—drought near the equator, Central America and the western Pacific, alongside heavy rain in the Horn of Africa, the western US and South America's Pacific coast—may differ from past strong El Niños because of added warming from climate change.
The EU's climate service confirmed that August matched July 2023 as the hottest month ever measured, with global temperatures averaging 1.65C above pre-industrial levels. Scientists attribute the spike to a combination of long-term climate change and an intensifying El Nino pattern in the Pacific. The month also closed out western Europe's hottest summer on record, exceeding the deadly heat wave of 2003.
Researchers led by psychologist Tobias Brosch at the University of Geneva analyzed 71 studies covering over 216,000 participants to compare climate-communication strategies. Published in the Journal of Environmental Psychology, the review found that messages evoking awe, wonder or hope were more effective at motivating climate-friendly behavior than purely scientific fact-based appeals, while messages emphasizing personal responsibility often failed or backfired.
The EU's Copernicus climate agency reported that August tied with July 2023 as the hottest month ever measured globally, following a summer that also produced the second-hottest June and July on record. NOAA separately confirmed this was the hottest US summer, surpassing the Dust Bowl era, while global average temperatures ran 1.65°C above preindustrial levels.
Copernicus reported that August 2023 statistically tied July 2023 as the hottest month ever measured, with global average temperatures reaching 16.96 degrees Celsius. Scientists attribute the extreme heat to a combination of long-term human-caused climate change and a strong El Nino weather pattern, noting the reading was 1.65 degrees Celsius above pre-industrial levels.
