Study Bolsters Theory of Heat Source Under West Antarctica
A new NASA study adds evidence that a geothermal heat source called a mantle plume lies deep below Antarctica's Marie Byrd Land, explaining some of the melting that creates lakes and rivers under the ice sheet.
Los negociadores sobre el clima que se reúnen en Alemania esta semana aún están a tono con el éxito del Acuerdo de París hace dos años. Pero a medida que comienzan a armar un libro de reglas para garantizar que se cumplan las promesas nacionales hechas en París, llega una dosis dura de realidad. Esas promesas, que limitan las emisiones de gases de efecto invernadero desde ahora hasta el año 2030, solo entregarán un tercio de los recortes necesarios para poner al mundo en camino de mantener el calentamiento por debajo de los 2 grados centígrados prometidos.
Central to the field of ecology is the mantra that species do not exist in isolation: They assemble in communities — and within these communities, species interact. Predators hunt prey. Parasites exploit hosts. Pollinators find flowers.
NASA-NOAA's Suomi NPP satellite has been providing forecasters with imagery of Tropical Storm Rina as it moves north through the Central Atlantic Ocean.
Encouraging children to drink plain water with their school lunches could prevent more than half a million youths in the U.S. from becoming overweight or obese, and trim the medical costs and indirect societal costs associated with these problems by more than $13 billion, a new study suggests.
Heat from friction could power hydrothermal activity on Saturn's moon Enceladus for billions of years if the moon has a highly porous core, according to a new modeling study by European and U.S. researchers working on NASA's Cassini mission.
The study, published today in the journal Nature Astronomy, helps resolve a question scientist have grappled with for a decade: Where does the energy to power the extraordinary geologic activity on Enceladus come from?
