Dust deposits give new insights into the history of the Sahara

Remote Saharan dust influences Earth's radiation budget and tropical North Atlantic ocean-atmosphere temperature variability that might even attenuate Hurricane activity. In a new research stu...

Scientists shed light on carbon's descent into the deep Earth

The presence of carbonates in the Earth's mantle is known from diamond inclusions, but how carbon is transported there remains a mystery. Scientists now reveal two new iron carbonate compounds...

Sea cave preserves 5,000-year snapshot of tsunamis

Scientists digging in a sea cave in Indonesia have discovered the world's most pristine record of tsunamis, a 5,000-year-old sedimentary snapshot that reveals for the first time how little is ...

Thawing permafrost releases old greenhouse gas

The thawing permafrost soils in the Arctic regions might contribute to the greenhouse effect in two respects: on the one hand rising temperatures lead to higher microbial methane production close t...

Too many bats are being killed for research

The work of zoologists worldwide is often an important asset for biodiversity protection, but a new article notes that scientists kill many bats -- even of threatened species -- to study them.

Destruction of wetlands linked to algal blooms in Great Lakes

Canada's current wetland protection efforts have overlooked how the environment naturally protects fresh-water resources from agricultural fertilizer contaminants.

Did life begin on land rather than in the sea?

A new discovery pushes back the time for the emergence of microbial life on land by 580 million years and also bolsters a paradigm-shifting hypothesis that life began, not in the sea, but on land.

Titan simulations show importance of close two-way coupling between human and Earth systems

By using supercomputers such as the Oak Ridge Leadership Computing Facility's Titan, a large multidisciplinary team of scientists developed a new integrated climate model designed to reduce un...

Human-made aerosols identified as driver in shifting global rainfall patterns

Scientists found that aerosol particles released into the atmosphere from the burning of fossil fuels are a primary driver of changes in rainfall patterns across the globe.

Removing CO2 from the air required to safeguard children's future

Reducing greenhouse-gas emissions is not enough to limit global warming to a level that wouldn't risk young people's future, according to a new study by scientists who say we need negativ...
