Internet cable reveals the source of underwater vibrations

Scientists have harnessed Internet-transmitting fiber-optic cables to overcome a long-standing geophysical challenge: identifying where seismic noise in the ocean originates. Tiny vibrations of Earth called microseisms are ...

MESSENGER reveals a more dynamic Mercury surface

Compared with Earth, the surfaces of most other objects in the solar system appear largely static. Planetary scientists have long believed that impacts from space debris are the principal source of change on these surfaces ...

Satellites can accurately take Earth's temperature

Changes in near-surface air temperatures around the world are one of the most important indicators of climate change. But to fully capture the impact rising temperatures have on people, plants, and processes at Earth's surface, ...

Climate change is making lakes less blue

If global warming persists, blue lakes worldwide are at risk of turning green-brown, according to a new study which presents the first global inventory of lake color. Shifts in lake water color can indicate a loss of ecosystem ...

How we're reshaping global water storage

Globally, humans use about 4 trillion cubic meters of fresh water each year for everything from crop irrigation to cooling manufacturing equipment to generating electricity. In a recent study published in Earth's Future, ...

Capturing ocean turbulence at the underbelly of sea ice

Turbulence in the sea plays a key role in mixing ocean waters and transporting nutrients, heat, and dissolved gases. Sources of ocean turbulence are highly varied and include wind, currents, heating and cooling cycles, and ...

Tropical wetlands emit more methane than previously thought

Since 2007, the world's atmospheric methane concentration has risen at an accelerated rate, but scientists aren't exactly sure why. This is a problem, because methane is a particularly potent greenhouse gas. It has more than ...

Urban overheating risks are personal, study finds

Global warming and urbanization are expected to increase heat hazards in cities around the world, but higher temperatures may not always lead to higher health risks, according to a new study in Earth's Future.
