NASA studies details of a greening Arctic
The northern reaches of North America are getting greener, according to a NASA study that provides the most detailed look yet at plant life across Alaska and Canada. In a changing climate, almost a third of the land cover - much of it Arctic tundra - is looking more like landscapes found in warmer ecosystems.
With 87,000 images taken from Landsat satellites, converted into data that reflects the amount of healthy vegetation on the ground, the researchers found that western Alaska, Quebec and other regions became greener between 1984 and 2012. The new Landsat study further supports previous work that has shown changing vegetation in Arctic and boreal North America.
Las abejas recogen un número sorprendente de pesticidas en plantas no cultivadas
Un estudio de la Universidad de Purdue muestra que las abejas recogen la mayor parte de su polen de plantas que no son de cultivo, incluso en las zonas dominadas por el maíz y la soja y que el polen se contamina constantemente con una serie de plaguicidas agrícolas y urbanos a lo largo de la temporada de crecimiento.
Map Shows Where Fossil Fuels Should Stay in the Ground
We know that we need to keep the vast majority of fossil fuels in the ground in order to limit global warming to 1.5 degrees Celsius. Now, a new project from the University of Arizona shows us exactly where we need to keep these fuels in the ground.
High blood pressure linked to short-, long-term exposure to some air pollutants
High blood pressure was associated with short-term and long-term exposure to some air pollutants commonly associated with the burning/combustion of fossil fuels, dust and dirt, a new study shows. Researchers suggest people -- especially those with high blood pressure -- limit their time outdoors when pollution levels are high.
Renewable Energy Closes "The Gap"
The Renewables Energy Policy Network for the 21st Century - shows that renewables are now firmly established as competitive, mainstream sources of energy in many countries around the world, closing the gap between the energy haves- and have-nots
