Events

The iron ocean

Through dust, not rust, the metal plays a complex, controversial role in Earth’s climate

Champagne bubbles: the science

As you uncork that bottle and raise your glass, take time to toast physics and chemistry along with the New Year

Eyes on the deep

Decades of exploring the seafloor have helped oceanographer Samantha Joye tackle marine issues — from the underwater movement of oil from Deepwater Horizon to the biology of remote microbial communities

Why solar geoengineering should be part of the climate crisis solution

The controversial technology of reflecting sunlight away from the planet could help blunt the worst impacts of climate change

Marine wildlife is starting to suffocate

Global warming and agricultural runoff have driven the loss of oxygen in oceans around the world, with looming ecological consequences.

10 years after the nuclear meltdown at Fukushima Daiichi, I’m still worried

OPINION: The cleanup of the past decade at the Japanese power plant could be set back if authorities don’t properly handle a massive stockpile of contaminated water

Rising to meet the tide

As the threat of coastal flooding grows, scientists are responding with an inundation of data. Faster and more accurate forecasts can save lives and property.

As climate changes, so does life in the planet’s soils

To understand what might be lost, ecologist Janet K. Jansson taps molecular methods to explore Earth’s underground microbes, from the permafrost to the grasslands

As the Arctic warms, it’s losing more than just ice

SLIDESHOW: Also at risk are the many hidden habitats built into the sea’s frozen wilds.

The marks of extinction

The mass die-offs of Earth’s past may hold clues to our future

Has humankind driven Earth into a new epoch?

Our mark on Earth is so profound that some argue it’s time to bid goodbye to the current geological time period — the Holocene — in favor of a new one: the Anthropocene.

What did ancient people eat? Scientists find new clues in old pottery

Remnants of molecules and microbes in shards of cooking pots help researchers reconstruct prehistoric cuisines. On the menu: stews, cheese and fermented drinks.

Quest to secure the world’s vanishing ice

Glaciologists dream of a cold-storage vault in Antarctica to preserve key samples of the paleoclimate

The tricky task of tallying carbon

To slow or stop global warming, the world agrees it must cut carbon dioxide emissions. But monitoring each nation’s output of greenhouse gases is not always straightforward.

The race against radon

Scientists are working to map out the risks of the permafrost thaw, which could expose millions of people to the invisible cancer-causing gas

Fighting fire with fire ... and fauna

Climate change is aggravating the seasonal burns that Australia has always known. They won’t be snuffed out, but new ecological strategies may help.

The quest to understand tornadoes

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

As glaciers retreat, new streams for salmon

Ecologist Sandy Milner has traveled to Alaska for decades to study the development of streams flowing from melting glaciers. He’s seen insects move in, alders and willows spring up, and spawning fish arrive in thousands.

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.

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
