Keeping trees in the ground where they are already growing is an effective low-tech way to slow climate change

Permanently protecting large, mature forests is a faster and cheaper way to stabilize Earth's climate than complex carbon capture and storage schemes, and more effective than planting new trees.

Cities can help migrating birds on their way by planting more trees and turning lights off at night

Cities are danger zones for migrating birds, but there are ways to help feathered visitors pass through more safely

Two-thirds of Earth's land is on pace to lose water as the climate warms – that's a problem for people, crops and forests

The projected loss of water storage on land as global temperatures rise is especially alarming in the Southern Hemisphere – and in parts of the US.

Tiny treetop flowers foster incredible beetle biodiversity

In the Amazon, beetles and flowering trees have developed a tight bond. Hundreds of beetle species thrive off of and pollinate blossoms, helping to maintain some of the highest biodiversity on Earth.

Climate change is making autumn leaves change colour earlier – here's why

Warmer temperatures cannot increase the amount of carbon deciduous trees absorb in each growing season, a new study suggests.

Evolution on the smallest of scales smooths out the patchwork patterns of where plants and animals live

Local adaptation allows plants and animals to thrive in a diversity of places. Sometimes adaptation sharpens patterns of where organisms live, but 85% of the time, it creates a more homogeneous world.

The world's southernmost tree hangs on in one of the windiest places on Earth – but climate change is shifting those winds

A team of researchers found the southernmost tree and forest on Earth at the extreme tip of South America. Wind limits where trees grow on Isla Hornos and those wind patterns are shifting.

Across the world, trees are growing faster, dying younger – and will soon store less carbon

We analysed 210,000 tree ring records from 80 different species, and found the trade off between growth and lifespan may neutralise the forest carbon sink.
