A new graphic created by NASA and the Japan Aerospace Exploration Agency illustrates the severity of a recent rainstorm that caused widespread flooding in Louisiana this week, killing 11 people and forcing tens of thousands of residents from their homes.
The more it swarms, crawls and flies the better it is for humans. This is the finding of a study published in "Nature". More than 60 researchers from a number of universities were involved, including the Technical University of Munich, the Institute of Plant Sciences at the University of Bern and the Senckenberg Biodiversity and Climate Research Centre in Frankfurt. A diverse ecosystem populated by many species from all levels of the food chain provides higher levels of ecosystem services, the team reports. Even rather unpopular insects and invisible soil-dwelling organisms are important in maintaining a wide range of ecosystem services. The results underline the necessity of maintaining species-rich ecosystems for the good of humanity.
Nuestro planeta se encuentra en el centro de dos inmensas donas concéntricas de potente radiación: los cinturones de Van Allen, que albergan un enjambre de partículas cargadas que son atrapadas por el campo magnético de la Tierra.
"The Arctic sea ice responded very rapidly to past climate changes. During the coldest periods of the past 90,000 years the sea ice edge spread relatively quickly to the Greenland-Scotland Ridge, and probably far into the Atlantic Ocean." says first author Ulrike Hoff, a researcher at Centre for Arctic Gas Hydrate, Environment and Climate (CAGE).
Sea ice amplifies the climate changes that are occurring at any given time. Its growth and melting has profound effects on climate, the marine environment and ocean circulation.

¿Ha pensado alguna vez poner las aguas residuales en las plantas? Los científicos dicen que los lodos térmicamente acondicionados de una planta de tratamiento sirven como un excelente fertilizante para mejorar las propiedades del suelo. Esto fue publicado recientemente en la revista de acceso abierto Frontiers in Nutrition. ¿La principal ventaja sobre los fertilizantes comerciales? la reutilización sostenible de los recursos finitos esenciales y el fósforo.
Western communities are facing effects of a warming climate with slower and earlier snowmelt reducing streamflows and possibly the amount of water reaching reservoirs used for drinking water and agriculture, according to a study published in July.
"As the climate warms, there is actually a slower snowmelt - both in timing and rates, which makes for a less efficient streamflow," Adrian Harpold, ecohydrologist at the University of Nevada, Reno said. Harpold, who initiated the study two years ago at the University of Colorado Boulder, is a co-author of the paper published in AGU publications Geophysical Research Letters.
