Indonesia's fires grew roughly fourfold after June as the strongest El Niño on record began forming, with emissions on track to match 2015. The event is still strengthening on 1.4C of warming, and the year's outlook leans on a short record of past El Niños.

Scanner authors writing on dev.to hand-checked 60 public pull_request_target workflows and judged 6 exploitable by anyone who can open a pull request. About as many looked dangerous and were safe, so an audit has to read what runs after the checkout.

Australia's Darwin ash-advisory centre used ESA's EarthCARE lidar to confirm that Anak Krakatau's westward plume sat near 15 km, as forecast. That check brought a satellite built to study clouds and Earth's energy balance into aviation advice in near-real time.

Copernicus logged 21.10 C on Aug. 22, one hundredth of a degree above March 2024. The timing, not the margin, is what should move planning assumptions.

Jha and Byrne varied the rate at which dry air mixes into convective plumes across ERA5 and CESM2, and found it significantly moves moist-heat extremes outside the tropics, which means a swept parameter sits underneath the wet-bulb projection.

Google's new model trains on sparse station observations instead of six-hour-old physics output, which is what buys the 5 km surface grid. Wind aloft still comes out at 25 km, the same as WeatherNext 2.

The last two international estimates of the annual motion disagreed by seven millimetres, nearly as much as the motion itself, so a JPL-led team rebuilt the measurement by adding GPS and low-orbit satellites to laser ranging.

University of Chicago researchers project 451,000 extra heat deaths worldwide from El Niño by February 2027, with 31,400 of them in Nigeria. The estimate rests on a six-month forecast, so the Sahel has only this season to prepare.
Reality
The Climate Impact Lab ran a European seasonal temperature outlook through local mortality curves fitted for 24,000 regions, and the authors want health ministries to treat the result as a schedule for moving staff, water and cooling.

The eastern Pacific is running 2.1 C above average on weekly NOAA data, past the 2 C mark for a super event. The official strength category comes from three-month averages, and the regional outlook comes with a caveat attached.

Two researchers scored 35 years of ECMWF forecasts against the observed weather and found accuracy rises with national income at every lead time out to a week. The reasons are mostly geographic and only partly a matter of spending.

A UNESP-led team read 207 daily rain samples collected in Manaus between March 2023 and February 2025 and found two Atlantic systems taking turns at setting the isotope ratio. The early-warning use is still untested.
Reality
A NASA Goddard team compared the 1980s with 2015 to 2024 and found extreme heat seasons growing at both ends, later in the western United States and earlier in western Europe, on schedules no summer calendar tracks.
Reality
Almost 650,000 hectares have burned across the EU in more than 1,913 large fires, close to double the long-term average, with the anomaly concentrated in the north and west rather than the fire-prone south.
Reality
The model feeds Search, Maps and Gemini and ships on Google Cloud, so anyone whose product depends on a forecast now has a supplier to choose and an accuracy claim from a startup's benchmark to read closely.
Reality
A five-season Atlantic study led from the University of Miami found ECMWF's AI ensemble carrying more tropical cyclogenesis signal at 84 to 120 hours and less at 36 to 48, which makes it guidance rather than a substitute.
Reality
Copernicus says the emissions match previous major El Nino years for the date. The 1997 analogue reached 2.5 gigatonnes of CO2, roughly four months of global fossil fuel burning at then-current rates.
