For corals adjusting to climate change, it’s survival of fattest and most flexible

The future health of the world’s coral reefs and the animals that depend on them relies in part on the ability of one tiny symbiotic sea creature to get fat — and to be flexible about the type of algae with which it cooperates. (more…)

It could also work for Mars

Impact glass stores biodata for millions of years

Bits of plant life encapsulated in molten glass by asteroid and comet impacts millions of years ago give geologists information about climate and life forms on the ancient Earth. Scientists exploring large fields of impact glass in Argentina suggest that what happened on Earth might well have happened on Mars millions of years ago. Martian impact glass could hold traces of organic compounds. (more…)

How (and when) Earth got its plated shell

New Yale-led research suggests how and when Earth came to develop one of its most distinct features — rigid tectonic plates — and why Venus, Earth’s twin-like neighbor, never has.

“We think it all comes down to the behavior of tiny grains of minerals within rocks,” said Yale geophysicist David Bercovici, lead author of research published online April 6 in the journal Nature. (more…)

Amazon Carbon Dynamics: Understanding the Photosynthesis-Climate Link

FLAGSTAFF, Ariz. — Researchers at the U.S. Geological Survey, the University of Michigan, the University of Arizona, and the University of Technology, Sydney (Australia) are collaborating with scientists in Brazil on a three-year research project that investigates a basic yet unanswered question in Earth-system and global carbon-cycle science: What controls the response of photosynthesis in Amazon tropical forests to seasonal variations in climate?

Results of the study will help improve the reliability of global climate forecasts by guiding improvements in the treatment of tropical forest photosynthesis and related water-cycle processes in Earth-system models. (more…)

Glaciers existed in Britain as late as Georgian era

New evidence indicates glaciers present 11,000 years later than believed

Research led by a scientist from the University of Exeter has shown that Britain was home to small glaciers within the last few centuries – around 11,000 years later than previously thought.

Dr Stephan Harrison of Geography has established that small glaciers almost certainly existed in the Cairngorm mountain range in Scotland as recently as the 18^th century, contrary to the long held belief that Britain’s last glaciers melted around the 9^th millennium BC. (more…)

Watching Earth’s Winds, On a Shoestring

Built with spare parts and without a moment to spare, the International Space Station (ISS)-RapidScat isn’t your average NASA Earth science mission.

Short for Rapid Scatterometer, ISS-RapidScat will monitor ocean winds from the vantage point of the space station . It will join a handful of other satellite scatterometer missions that make essential measurements used to support weather and marine forecasting, including the tracking of storms and hurricanes. It will also help improve our understanding of how interactions between Earth’s ocean and atmosphere influence our climate. (more…)

Cool heads likely won’t prevail in a hotter, wetter world

Should climate change trigger the upsurge in heat and rainfall that scientists predict, people may face a threat just as perilous and volatile as extreme weather — each other.

Researchers from Princeton University and the University of California-Berkeley report in the journal Science that even slight spikes in temperature and precipitation have greatly increased the risk of personal violence and social upheaval throughout human history. Projected onto an Earth that is expected to warm by 2 degrees Celsius by 2050, the authors suggest that more human conflict is a likely outcome of climate change. (more…)

Newly discovered ocean plume could be major source of iron

Study reveals micronutrient riches rising from the Southern Mid-Atlantic Ridge

Scientists have discovered a vast plume of iron and other micronutrients more than 1,000 km long billowing from hydrothermal vents in the South Atlantic Ocean. The finding, soon to be published in the journal Nature Geoscience, calls past estimates of iron abundances into question, and may challenge researchers’ assumptions about iron sources in the world’s seas.

“This study and other studies like it are going to force the scientific community to reevaluate how much iron is really being contributed by hydrothermal vents and to increase those estimates, and that has implications for not only iron geochemistry but a number of other disciplines as well,” says Mak Saito, a WHOI associate scientist and lead author of the study.
