A carbon credit doesn't expire like a coupon, it gets 'retired' once and only once. Here's how retirement actually works, and the separate durability question it doesn't answer.

The White House set a 15% tariff on polysilicon and, separately, a hard minimum price. The two tools do very different jobs, and the gap between them explains why solar makers are watching closely.

A flash drought can turn a healthy field into a stressed one within days, driven by heat and wind rather than a lack of rain. Farmers and forecasters are racing to catch up.

The National Weather Service quietly retired "Excessive Heat Warning" in 2025. Here's what the new terms mean, and the exact thresholds regional offices use to issue them.

More than 165 million Americans face major or extreme heat risk this week as a record-threatening heat dome settles over the East Coast and Midwest through the July Fourth weekend — and complicates World Cup matches.

A solstice-week heat dome pushed France toward a national record and shut hundreds of schools, with Britain's peak still days away.

A heat dome has settled over Western Europe for the summer solstice, with France warning Monday could be its hottest day on record and 53 departments already under an orange alert.
