Trump said the methane rule is terminated; EPA's signed paper is a proposal. Its impact analysis explains the $45 billion, the 210 million barrels and the 60 million tons.

Sunday's preliminary 7.71 feet left Los Angeles about 2.5 inches short of its 7.92-foot record. Astronomy sets the base; the Pacific's extra water decides whether this week beats it.

Vance weakened to 85 mph by 3 a.m. CST Sunday and the center is forecast to stay offshore, yet the hurricane center still expects flooding rain and rough surf.

The Imperial and LSHTM estimate of 50,391 heat deaths in 854 cities is a record in its own 854-city series, on either population base, but it is a cities-only model, and the 71% headline gap shrinks like for like.

Applied to UNEP's 2025 total, the 18% cut needed by 2030 is about 10.5 billion tonnes, and the yearly pace climbs from about 3.9% to 10.8% by 2040. Current national plans cover under half of the first step.

Palembang's airport read 50 meters of visibility on the morning Indonesia's first dry-ice flight was due. A cheap experiment is worth trying, but haze that swings on its own and 1.5 tons of ice against a city's worth of air make success hard to prove.

The notice list is a ceiling, not a forecast. Here is how PG&E's fuel-moisture and ignition models pick circuits, why Paradise is in scope, and how often warnings end in outages.

After 1,000 days without an agreed report timeline, the IPCC's Addis Ababa session is also deciding whether the panel can set a 2027 budget at all.

Simon's eyewall sits very near Mexico's Pacific coast and forecasters can't say whether it will make landfall. The same few miles of track decide whether a World Bank catastrophe bond pays Mexico anything.

Japan's gauge broke a 1997 record in September. NOAA's official measure, which strips out the warming of the whole tropical ocean, is still short of its 1983 high, and that gap shapes what this winter can expect.

The Environment Agency moved Yorkshire into drought on Oct. 9, yet Yorkshire Water plans no restrictions. The legal split, the reservoir numbers against last year's ban, and what winter rain must do.

In the UTC time the hurricane record uses, Isaias was upgraded three and a half hours after 1905's first hurricane. Wind shear, El Niño's brake all season, now hinges on a trough as Isaias nears the Gulf Coast and Rachel heads for Southern California.

Frost gets the credit for ending mosquito season, but shrinking daylight flips the switch weeks earlier, and many mosquitoes simply wait out winter in garages and as eggs.

The three cold-weather alerts measure different risks, their cutoffs change from one forecast office to the next, and all of them disappear once your growing season is over.

Day length, the normal trigger for fall color, is the same every year. When a tree turns weeks early, drought or damage is usually doing the work, and 2026 has offered plenty of both.

A derecho and a tornado can look equally destructive, but only one of them spins. Here's the wind pattern, and the wind-speed math, that tells them apart.

Türkiye and Australia split the COP31 presidency to end a yearlong hosting fight. This week Türkiye's climate minister said the deal doesn't make them equals.

The acrid, chemical smell in wildfire smoke isn't your imagination — it's benzene and formaldehyde, and sometimes it's literally burning plastic.

Before a single drop of storm runoff arrives, California dam operators are already emptying space for it. New atmospheric-river forecasting means they can now time that release to the hour.

Twice a year, the moon and sun line up to push ordinary high tides over seawalls with no storm in sight, and South Florida just published exactly when it happens next.
