London's temperatures reached above 26C, making it hotter than popular destinations like Ibiza and Barcelona. This marks the warmest day of the year so far, surpassing 21C recorded on Tuesday.
Research from the Insurance Institute for Business & Home Safety consistently identifies wind-borne embers, firebrands carried well ahead of the fire front, as a dominant cause of residential structure loss in wildfires.
The Springs fire in Riverside county has grown to 3,500 acres, prompting local authorities to issue several evacuation orders. The fire is concentrated in an area mostly north and east of Lake Perris, burning portions of the surrounding state recreation area.
Research shows that summertime conditions can lead to cognitive impairments, particularly in memory and concentration. Factors such as sleep disruption, heat, dehydration, and smoke exposure are significant contributors to these effects.
Not only will temperatures break March monthly records, but this heatwave will even break April records. Over the next week, around 800 high temperature records are forecast to be neared, tied or broken at 165 locations in Western and Central states - some by more than 10 degrees - with unusual warmth set to linger into late March.
During this heat wave, "not only are daily temperature records likely to be broken across the region, but even the high temperature records for any day in the entire month of March," the National Weather Service said in a Tuesday morning forecast.
We found our route but advanced only a few hundred yards before encountering an impassable logjam. The dense forests on either side meant that we couldn't go around it, only through.
Because the past three years have shattered temperature records, researchers have been exploring whether global warming is accelerating, and if so, why. Many scientists agree that the rate at which it is increasing has picked up. This is mainly because of a reduction in air pollution following the introduction of fuel regulations for international shipping (which has resulted in fewer pollutant particles that reflect sunlight into space and seed insulating clouds).
The past 11 years are the warmest since records began, with the past three top of the leader-board. Hottest of the lot was 2024, which coincided with a strong Niño-a pattern of winds and ocean currents that nudges the thermometer upwards-combined with a peak of the 11-year solar cycle when the sun shines brightest. But in 2025 El Niño tailed off, to be replaced by its opposite pattern, La Niña, and the sun-only a minor part of the story in any case-began to dim.
