Climate Change

The hornet has landed: Scientists combat new honeybee killer in US

An invasive yellow-legged wasp has been decimating beehives in Europe — and bedeviling Georgia since last summer. Researchers are working nest by nest to limit the threat while developing better eradication methods.

Geothermal power heats up

Long confined to regions with volcanic activity, geothermal promises to become a much more versatile energy source thanks to new technologies

Why are there so many beetle species?

Diet played a key role in the evolution of the vast beetle family tree

Nuclear’s role in a net-zero world

Is nuclear power a necessary part of the energy transition away from fossil fuels? As the debate rages on, new technologies and smaller reactors may be shifting the balance.

How to overcome political polarization on climate change

Conversations — in real life — can help bridge the partisan divide, but the trick is to have some structure to the discussion, says a human ecologist

Hunting sky islands for genetic clues to climate resilience

OPINION: Isolated mountaintops are hotbeds of evolutionary adaptation and great places to study how climate change affects ecosystems

Moving trees north to save the forests

As the world warms, trees in forests such as those in Minnesota will no longer be adapted to their local climates. That’s where assisted migration comes in.

A big boost to Europe’s climate change goals

The bloc aims to become the first carbon-neutral continent. A new policy called CBAM will assist its ambitions — and may persuade other countries to follow in its footsteps.

Losing the connection between the Andes and the Amazon: A price of peace in Colombia

The South American country, where the biodiversity of the Andes meets that of the Amazon, is losing the great natural wealth of some 1,500 square kilometers of forest each year, mainly in areas formerly under guerrilla control

The hidden threat from rising coastal groundwater

OPINION: Sea level rise won’t hit just homes on shorefronts, but also the infrastructure beneath our feet

Indigenous languages are founts of environmental knowledge

Peoples who live close to nature have a rich lore of plants, animals and landscapes embedded in their mother tongues — which may hold vital clues to protecting biodiversity

Forests are under attack from invasive species

OPINION: International commerce and travel bring ecological destruction to the world’s most cherished natural places. We need to do more to stop the assault.

Green shipping picks up speed

An international treaty aims to bring the shipping industry to net-zero emissions by around 2050. Can novel fuels, wind power and coordination on a global scale get it there?

The race to understand polar ice sheets

As glacial cliffs break off and destabilize frozen landscapes, glaciologist Richard Alley focuses on the fractures. The work could improve predictions about future sea-level rise.

How wind turbines could coexist peacefully with bats and birds

As wind power grows around the world, so does the threat the turbines pose to wildlife. From simple fixes to high-tech solutions, new approaches can help.

Pursuing fusion power

Scientists have been chasing the dream of harnessing the reactions that power the Sun since the dawn of the atomic era. Interest, and investment, in the carbon-free energy source is heating up.

As the climate changes, plants must shift their ranges. But can they?

Lots of them depend on fruit-eating birds and mammals to spread their seeds. But it’s debatable whether the animals — many in trouble themselves — can disperse seeds far and fast enough to keep pace with a warming world.

The quest to understand tornadoes

Scientists are still grappling with how and why violent twisters form. Will new technology and computing power help?

Leaning into Indigenous knowledge on climate change

Native peoples attuned to the natural world have long collected detailed environmental information. Now scientists are cataloging these observations and learning how they’re affecting Indigenous communities globally.

Does it work to pay people not to cut the forest?

Evidence that the approach helps to save trees, preserve ecosystems and reduce carbon emissions is often hard to come by. But it can succeed if it’s done right, says an economist.
