The Greenland and Antarctic ice sheets will make a dominant contribution to 21st century sea-level rise if current climate trends continue. However, predicting the expected loss of ice sheet mass is difficult due to the complexity of modeling ice sheet behavior.
To better understand this loss, a team of Sandia National Laboratories researchers has been improving the reliability and efficiency of computational models that describe ice sheet behavior and dynamics. The team includes researchers Irina Demeshko, Mike Eldred, John Jakeman, Mauro Perego, Andy Salinger, Irina Tezaur and Ray Tuminaro.
This weekend bird enthusiasts from around the world will become citizen scientists for a few days during the 19th annual Great Backyard Bird Count, which is happening this year February 12-15.
During this four-day event, which is organized by the Cornell Lab of Ornithology, the National Audubon Society and Bird Studies Canada, people will be headed outdoors to count their local birds in the name of science.
The Obama administration’s Clean Power Plan suffered a setback on Tuesday when the Supreme Court granted a stay to the program. In a 5-4 decision, the court sided in favor of petitioning states, utilities and coal companies that claimed that the federal government was overreaching its powers when it attempted to establish a national plan to move away from fossil-fuel based power. Requests for the Supreme Court to impose the stay were submitted in January after an appeals court ruled that the plan could proceed while legal challenges were being heard.
The Supreme Court’s ruling is an about-face to the U.S. Court of Appeals for the District of Columbia Circuit, and it comes at a critical time for the Obama administration’s clean energy program, especially in light of the upcoming elections in November. While the administration can appeal the Supreme Court’s order, arguments would not be considered until June and, pending acceptance by the higher court, likely wouldn’t be scheduled until October or later this year. That leaves the fate of the Clean Power Plan in the hands of the upcoming presidency.
The Aedes mosquitos that carry the Zika virus and dengue fever are not just perfectly adapted to life in cities, writes Nadia Pontes. They are also being helped along by warming climates which increase their range. It's time to get serious about the health implications of a hotter planet.
Global warming affects the abundance and distribution of disease vectors. As regions that used to be drier and colder start to register higher temperatures and more rain, mosquitoes expand their breeding areas, which increases the number of populations at
The explosion in the number of Latin American cases of microcephaly - a congenital condition associated with maldevelopment of the brain - has become an international emergency due its "strongly suspected"link with the rapidly spreading Zika virus, according to the World Health Organisation(WHO).
Planes flying between Europe and North America will be spending more time in the air due to the effects of climate change, a new study has shown.
By accelerating the jet stream – a high-altitude wind blowing from west to east across the Atlantic – climate change will speed up eastbound flights but slow down westbound flights, the study found. The findings could have implications for airlines, passengers, and airports.
The Earth may suffer irreversible damage that could last tens of thousands of years because of the rate humans are emitting carbon into the atmosphere.
In a new study in Nature Climate Change, researchers at Oregon State University, Lawrence Livermore National Laboratory and collaborating institutions found that the longer-term impacts of climate change go well past the 21st century.
“Much of the carbon we are putting in the air from burning fossil fuels will stay there for thousands of years — and some of it will be there for more than 100,000 years,” said Peter Clark, an Oregon State University paleoclimatologist and lead author on the article. “People need to understand that the effects of climate change on the planet won’t go away, at least not for thousands of generations.”
LLNL’s Benjamin Santer said the focus on climate change at the end of the 21st century needs to be shifted toward a much longer-term perspective.
Everyone needs clean air to survive, yet somehow it is not an internationally recognized human right. That probably has something to do with the fact that over half of the world’s population live in areas where they breathe in toxic air. Altogether, that means there are more than 3.5 billion people inhaling dangerous air into their lungs on a daily basis.
Bananas are at the sharp end of industrial agriculture's chemical war on pests and pathogens, writes Angelina Sanderson Bellamy. But even 60 pesticide sprays a year isn't enough to keep the diseases at bay. It's time to seek new solutions with little or no use of chemicals, working with nature, growing diverse crops on the same land - and breaking the dominance of the banana multinationals.
University of Alaska Fairbanks mathematicians and glaciologists have taken a first step toward understanding how glacier ice flowing off Greenland affects sea levels.
Andy Aschwanden, Martin Truffer and Mark Fahnestock used mathematical computer models and field tests to reproduce the flow of 29 inlet glaciers fed by the Greenland ice sheet. They compared their data with data from NASA's Operation IceBridge North aerial campaign.
The comparisons showed that the computer models accurately depicted current flow conditions in topographically complex Greenland.
A week's vacation may leave many adults with a heavier midsection--extra weight that can hang around even six weeks post-vacation.
A faculty member in the University of Georgia's College of Family and Consumer Sciences found that adults going on a one- to three-week vacation gained an average of nearly 1 pound during their trips. With the average American reportedly gaining 1-2 pounds a year, the study's findings suggest an alarming trend.
"If you're only gaining a pound or two a year and you gained three-quarters of that on a one- to three-week vacation, that's a pretty substantial weight gain during a short period of time," said Jamie Cooper, an associate professor in the college's department of foods and nutrition.
