U.S. records reveal the last 30 years were the hottest on record
New ‘climate normals’ show that average temperatures increased notably just since 1990.

‘Tree farts’ make up about a fifth of greenhouse gases from ghost forests
Heat-trapping gases from dead trees play an important role in the environmental impact of “ghost” forests.

Common parasite may help mussels survive heat waves
By whitening shells, the organism helps the shellfish stay cool on sunny days, a new study suggests.

Let’s learn about lightning
Around 100 times a second, every hour of every day, lightning strikes somewhere on Earth. It’s beautiful — and deadly.

Climate may have sent drift of the North Pole toward Greenland
This mid-1990s shift in the pole’s movement was driven by glacial melt. And that was triggered in part by climate change, a new study reports.

Local glacier could be gone in a decade, young scientist finds
A teen calculated the volume of a glacier by drilling into it with jets of steam — then used that to estimate how long before all its ice will be gone.

Urchin takeover underlies California’s vanishing kelp forests
Some 95 percent of kelp forests along its northern coast are gone. Meanwhile, sea otters are helping slow the loss of surviving kelp farther south.

Surfing the winds would make future jet travel greener
Simple route changes could drastically cut fuel use and greenhouse-gas emissions, a new study finds.
- Environment
The world wastes roughly a sixth of the food produced each year
A new United Nations report shows where wastes can be reduced, which would decrease hunger and emissions of climate-warming greenhouse gases.

Analyze This: Cows burp less methane after early-life treatment
Calves that receive the 14-week treatment belch less of the greenhouse gas, possibly due to shifts in their gut microbes.

Changing climate now threatens northern lakes year round
Lakes in northern climes are getting warmer, and that’s not good for people, plants or animals.

COVID-19 cut pollution in 2020, warming the atmosphere
Pandemic-related lockdowns briefly warmed the planet. The reason: The cleaner air carried fewer planet-cooling aerosols.
