NASA - National Aeronautics and Space AdministrationPasadena, CA – Five new NASA airborne field campaigns, including one managed by NASA’s Jet Propulsion Laboratory, Pasadena, California, will take to the skies starting in 2015 to investigate how long-range air pollution, warming ocean waters and fires in Africa affect our climate.

These studies into several incompletely understood Earth system processes were competitively selected as part of NASA’s Earth Venture-class projects. Each project is funded at a total cost of no more than $30 million over five years. This funding includes initial development, field campaigns and analysis of data.

NASA Study reveals degradation of Amazon Forest due to Climate Change

NASA - National Aeronautics and Space AdministrationPasadena, CA – An area of the Amazon rainforest twice the size of California continues to suffer from the effects of a megadrought that began in 2005, finds a new NASA-led study.

These results, together with observed recurrences of droughts every few years and associated damage to the forests in southern and western Amazonia in the past decade, suggest these rainforests may be showing the first signs of potential large-scale degradation due to climate change.
