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.

Una semana de vacaciones puede dejar a muchos adultos con un abdomen más pesado: un peso extra que puede prevalecer…incluso seis semanas después de vacaciones. Un miembro de la facultad en la Colegio de Ciencias de la Familia y el Consumidor de Georgia, encontró que los adultos que van de vacaciones de una a tres semanas, ganaron una media de cerca de medio kilogramo durante sus viajes. Según los informes, con el promedio de aumento de peso en EEUU, de medio kilo a un kilo cada año, los resultados del estudio sugieren una tendencia alarmante.

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 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).

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.
