Climate Change Will Drive Stronger, Smaller Storms in U.S.
The effects of climate change will likely cause smaller but stronger storms in the United States, according to a new framework for modeling storm behavior developed at the University of Chicago and Argonne National Laboratory. Though storm intensity is expected to increase over today’s levels, the predicted reduction in storm size may alleviate some fears…

Exploring the fate of the Earth's storehouse of carbon
A new study predicts that warming temperatures will contribute to the release into the atmosphere of carbon that has long been locked up securely in the coldest reaches of our planet.Soil and climate expert Katherine Todd-Brown, a scientist at the Department of Energy's Pacific Northwest National Laboratory, is an author of the paper, published in the Dec.…

Increasing tornado outbreaks — Is climate change responsible?
Tornadoes and severe thunderstorms kill people and damage property every year. Estimated U.S. insured losses due to severe thunderstorms in the first half of 2016 were $8.5 billion. The largest U.S. impacts of tornadoes result from tornado outbreaks, sequences of tornadoes that occur in close succession. Last spring a research team led by Michael Tippett, associate…

Corals much older than previously thought
Coral genotypes can survive for thousands of years, possibly making them the longest-lived animals in the world, according to researchers at Penn State, the National Marine Fisheries Service and Dial Cordy & Associates.The team recently determined the ages of elkhorn corals — Acropora palmata — in Florida and the Caribbean and estimated the oldest genotypes to…

Bioenergy grass can withstand freezing temperatures
March 2012 was unusually warm. Biomass crops around the Midwest were well established and thriving. But when a late frost came in mid-April, all of that changed.“When I went out in the morning, I was just shocked,” says University of Illinois agronomist D.K. Lee. “All the grasses were covered in frost. By noon, Miscanthus and…

Climate models may be overestimating the cooling effect of wildfire aerosols
Whether intentionally set to consume agricultural waste or naturally ignited in forests or peatlands, open-burning fires impact the global climate system in two ways which, to some extent, cancel each other out. On one hand, they generate a significant fraction of the world’s carbon dioxide emissions, which drive up the average global surface temperature. On…

With Climate Change, Not All Wildlife Population Shifts Are Predictable
Wildlife ecologists who study the effects of climate change assume, with support from several studies, that warming temperatures caused by climate change are forcing animals to move either northward or upslope on mountainsides to stay within their natural climate conditions.But a new study of lowland and higher-mountain bird species by wildlife ecologists Bill DeLuca and…

Groundwater helium level could signal potential risk of earthquake
Researchers at the University of Tokyo and their collaborators have revealed a relationship between helium levels in groundwater and the amount of stress exerted on inner rock layers of the earth, found at locations near the epicenter of the 2016 Kumamoto earthquake. Scientists hope the finding will lead to the development of a monitoring system…

Can Road Salt Change Sex Ratios in Frog Populations?
Naturally occurring chemicals found in road salts commonly used to de-ice paved surfaces can alter the sex ratios in nearby frog populations, a phenomenon that could reduce the size and viability of species populations, according to a new study by scientists at Yale and Rensselaer Polytechnic Institute (RPI).

West Antarctic ice shelf breaking up from the inside out
A key glacier in Antarctica is breaking apart from the inside out, suggesting that the ocean is weakening ice on the edges of the continent.The Pine Island Glacier, part of the ice shelf that bounds the West Antarctic Ice Sheet, is one of two glaciers that researchers believe are most likely to undergo rapid retreat, bringing more ice from…
