Greenland on thin ice?

Wed, 07 Dec 2016 00:00:00 EST

(University of Vermont) First-of-their-kind studies provide new insight into the deep history of the Greenland Ice Sheet, looking back millions of years farther than previous techniques allowed. However, the two studies present some strongly contrasting evidence about how Greenland's ice sheet may have responded to past climate change.



Most of Greenland ice melted to bedrock in recent geologic past, says study

Wed, 07 Dec 2016 00:00:00 EST

(The Earth Institute at Columbia University) Scientists have found evidence in a chunk of bedrock drilled from nearly two miles below the summit of the Greenland ice sheet that the sheet nearly disappeared for an extended time in the last million years or so. The finding casts doubt on assumptions that Greenland has been relatively stable during the recent geological past, and implies that global warming could tip it into decline more precipitously than previously thought.



Illinois researchers discover hot hydrogen atoms in Earth's upper atmosphere

Tue, 06 Dec 2016 00:00:00 EST

(University of Illinois College of Engineering) A team of University of Illinois researchers has discovered the existence of hot atomic hydrogen (H) atoms in an upper layer of Earth's atmosphere known as the thermosphere. This finding significantly changes current understanding of the H distribution and its interaction with other atmospheric constituents.

Sea ice hit record lows in November

Tue, 06 Dec 2016 00:00:00 EST

(University of Colorado at Boulder) Unusually high air temperatures and a warm ocean have led to a record low Arctic sea ice extent for November, according to scientists at the National Snow and Ice Data Center (NSIDC) at the University of Colorado Boulder. In the Southern Hemisphere, Antarctic sea ice extent also hit a record low for the month, caused by moderately warm temperatures and a rapid shift in circumpolar winds.



Scientists improve predictions of how temperature affects the survival of fish embryos

Tue, 06 Dec 2016 00:00:00 EST

(NOAA Fisheries West Coast Region) NOAA Fisheries Ecology Division and UC Santa Cruz researchers found the thermal tolerance of Chinook salmon embryos in the Sacramento River is much lower than expected from laboratory studies. Exploring the cause of this discrepancy led to new insights into how egg size and water flow affect the survival of fish eggs.



Ice age vertebrates had mixed responses to climate change

Tue, 06 Dec 2016 00:00:00 EST

(American Museum of Natural History) New research examines how vertebrate species in the eastern United States ranging from snakes to mammals to birds responded to climate change over the last 500,000 years. The study reveals that contrary to expectation, the massive glaciers that expanded and contracted across the region affected animal populations in different ways at different times. The analysis provides a window into how animals might react to any kind of climate change, whether glacial cycles or global warming.

Tue, 06 Dec 2016 00:00:00 EST

(University of Oklahoma) Robert D. Palmer, Ph.D., University of Oklahoma meteorology professor, associate vice president for research and executive director of the Advanced Radar Research Center, has been named an Institute of Electrical and Electronics Engineering Fellow. Among a select group of recipients recommended for the prestigious honor, Palmer is being recognized for contributions to atmospheric and meteorological radar science.



NREL 2016 Standard Scenarios outlook shows continued growth in renewables and gas

Tue, 06 Dec 2016 00:00:00 EST

(DOE/National Renewable Energy Laboratory) The Energy Department's National Renewable Energy Laboratory (NREL) has released the 2016 Standard Scenarios: A US Electricity Sector Outlook. The outlook shows significant projected growth in natural gas and renewables through 2050 driven by abundant, low-cost natural gas and renewable energy cost declines and performance improvements. The Standard Scenarios are designed to capture a range of possible futures across a variety of factors that could impact power sector evolution.

Iowa State scientist uses clam shells to help build 1,000-year record of ocean climate

Tue, 06 Dec 2016 00:00:00 EST

(Iowa State University) Just like trees have growth rings that scientists can study for clues about past growing conditions, clam shells have growth increments that offer clues about past ocean conditions. Scientists -- including Iowa State's Alan Wanamaker -- have sorted and studied thousands of clam shells to build a 1,000-year record of ocean conditions and climate changes at a spot just off North Iceland. The scientists' findings were just published online by the journal Nature Communications.



Researchers compare biodiversity trends with the stock market

Tue, 06 Dec 2016 00:00:00 EST

(Helmholtz Centre for Environmental Research - UFZ) Essential Biodiversity Variables (EBVs) have the potential to help stop species loss. An international research team is using an analogy to explain what these variables are. Just as the price of a share varies according to supply and demand and the prices of all individual shares are used to calculate the index of a stock exchange, data from observations of nature is used to calculate biodiversity variables.

Growing mosquito populations linked to urbanization and DDT's slow decay

Tue, 06 Dec 2016 00:00:00 EST

(University of California - Santa Cruz) Mosquito populations have increased as much as ten-fold over the past five decades in New York, New Jersey, and California, according to long-term datasets from mosquito monitoring programs. The number of mosquito species in these areas increased two- to four-fold in the same period. A new study finds the main drivers of these changes were the gradual waning of DDT concentrations in the environment and increased urbanization.



Researchers study sea spray to improve hurricane intensity forecasting

Mon, 05 Dec 2016 00:00:00 EST

(University of Miami Rosenstiel School of Marine & Atmospheric Science) A University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science research team is studying sea spray to help improve forecasting of hurricanes and tropical cyclones. In a recent study, the scientists found that in high winds conditions the amount of large sea spray droplets (over 0.5 milimeters in diameter) generated is as much as 1000 times more than previously thought.
