Large trees are essential for healthy cities

There is a growing interest in planting small trees in urban areas. However, large trees have significant advantages.

Thawing permafrost is roiling the Arctic landscape, driven by a hidden world of changes beneath the surface as the climate warms

Ground is collapsing and massive lakes are draining in a matter of days. Thawing permafrost is having profound effects on the region and its infrastructure.

Tropical forests can recover surprisingly quickly on deforested lands – and letting them regrow naturally is an effective and low-cost way to slow climate change

As governments and corporations pledge to help the planet by planting trillions of trees, a new study spotlights an effective, low-cost alternative: letting tropical forests regrow naturally.

Forests can’t handle all the net-zero emissions plans – companies and countries expect nature to offset too much carbon

Yes, trees and soils can absorb and store carbon, but the carbon doesn’t stay stored forever. That’s one of the problems with how net-zero plans for the climate are being designed.
Parts of Lake Elsinore, California, were overrun with muddy floodwater after a storm hit the Holy Fire burn scar in 2018. Jennifer Cappuccio Maher/Digital First Media/Inland Valley Daily Bulletin via Getty Images

Wildfire burn scars can intensify and even create thunderstorms that lead to catastrophic flooding – here’s how it works

An atmospheric scientist and sailplane pilot describes why large areas of burned land can produce clouds and rainstorms.

How special soil observatories in China are helping to create more sustainable agriculture

Soil degradation is a huge challenge for farmers around the world. But new research is showing how farmers can balance crop yields with protecting the environment.

To make agriculture more climate-friendly, carbon farming needs clear rules

Policymakers want to pay farmers for storing carbon in soil, but there are no uniform rules yet for measuring, reporting or verifying the results. Four scholars offer some ground rules.
