Hundreds of archaeologists provided on-the-ground data from across the globe, providing a new view of the long and varied history of people transforming Earth's environment.

Fossil fuels are heating the atmosphere – but the fact that we're burning them may not be the only reason.

Good news – underground aquifers could be a reliable source of drinking water in sub-Saharan Africa even as the climate warms.

Millions of Americans rely on groundwater for their lives and livelihoods, but regulation is piecemeal. A new study maps groundwater wells nationwide and finds that they are drilling steadily deeper.

Oxygen flooded the atmosphere for the first time and then ... nothing. Or so we thought.

Every day about 50 tons of rocks from space fall on Earth. An examination of these meteorites has inspired a new theory about how exactly these rocks formed.
The town of Schalkenmehren and its adjoining maar lake, Germany.
A maar is a volcanic crater, often filled with water. New research highlights the similarities between oral stories around the world that shed light on the formation of these craters.
New geological research reveals information about the Earth’s orbit and climate from billions of years ago.
Layers of rock provide a historical record of variations in the Earth's orbit, revealing information about the planet's climate billions of years ago.

Even in this fantasy world, geological processes like tectonic plate movement, earthquakes and volcanic eruptions would have built the mountains, carved the rivers, and created vast oceans.
Photographed on Kangaroo Island, this rock – called a ‘zebra schist’ – deformed from flat-lying marine sediments through being stressed by a continental collision over 500 million years ago.
Giant forces slowly move continents across a viscous layer of the Earth, like biscuits gliding over a warm toffee ocean. This stresses the continents, and twists and contorts the crust.

North Korea is a major military threat to the US and its Asian allies, but exactly how powerful are its nuclear weapons? An earth scientist explains why it's hard to answer this question.
The research vessel must dodge dangerous icebergs as it drills for sediment core samples.
A paleooceanographer describes her ninth sea expedition, this time retrieving cylindrical 'cores' of the sediment and rock that's as much as two miles down at the ocean floor.
Waves can be generated in lakes and other bodies of water when seismic energy travels through land.

If you've never heard of a form of wave called a 'seiche' – which can occur in swimming pools during earthquakes – this is your chance to catch up.
A psychologist explains why we should accept that we will never live in the Anthropocene.

In 2004 an underwater avalanche destroyed an oil platform off Louisiana, causing a 14-year spill. An expert on oil and gas seeps in the Gulf of Mexico warns that this could happen in other places.

Since 2008, Landsat data has been free for the world to use, spurring new applications and scientific research. But that door could soon slam shut.
A few days after baby molluscs come out from tiny eggs, they start building their shell layer after layer.
Emily Nunnell/The Conversation NY-BD-CC
Molluscs that have shells - like pipis, clams and oysters - have to build their own shell from scratch. And they keep building it their whole life, using chemicals from the sea and their own bodies.

When you study volcanoes at mid-ocean ridges, doing fieldwork means becoming an aquanaut – diving thousands of feet to the ocean floor in the submersible Alvin, trading tight quarters for amazing views.
