Climate Change

Can desalination quench agriculture’s thirst?

Miles away from the ocean, projects are afoot to clean up salty groundwater and use it to grow crops. Some say it’s a costly pipe dream, others say it’s part of the future.

The secrets of butterfly migration, written in pollen

Trillions of insects move around the globe each year. Scientists are working on new ways to map those long-distance journeys.

Sustainable building effort reaches new heights with wooden skyscrapers

Wood engineered for strength and safety offers architects an alternative to carbon-intensive steel and concrete

The dirt on biocrusts: Why scientists are working to save Earth’s living skin

Think twice before stepping on that crunchy top layer of soil. It may be a vital ecosystem — one that you can help protect.

To help with climate change, carbon capture will have to evolve

The technologies are a useful tool to reduce CO2 levels but have yet to move us away from fossil fuels

The greening of planes, trains and automobiles

We need new fuels to transport people and goods around the globe as society moves away from coal, natural gas and oil. Here’s how things are shaping up.

Cleaning up cow burps to combat global warming

New tools for lowering methane emissions from livestock are on their way

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?
