A Probe Into Pollution
In Early August, a modified DC-8 jetliner and a high-flying ER-2 will begin a major NASA airborne science campaign. The NASA Studies of Emissions, Atmospheric Composition, Clouds and Climate Coupling by Regional Surveys mission is the agency's most complex airborne science study of 2013. The field campaign draws together coordinated observations from NASA satellites, aircraft and an array of ground sites.
The flying laboratory will be the research "home" to 31 instruments that will study trace gases, black carbon, cloud particles and formaldehyde along with other airborne chemicals that contribute to pollution during the mission that runs August 10 through October 1 aiming to learn more about the characteristics of pollution movement during the hot US summer.

NASA scientists and an international team of researchers have found tropical ecosystems can generate significant carbon dioxide when temperatures rise, unlike ecosystems in other parts of the world. They discovered a temperature increase of just 1 degree Celsius in near-surface air temperatures in the tropics leads to an average annual growth rate of atmospheric carbon dioxide equivalent to one-third of the annual global emissions from fossil fuels and deforestation combined.
This study provides support for the "carbon-climate feedback" hypothesis proposed by many scientists. This hypothesis asserts a warming climate will lead to accelerated carbon dioxide growth in the atmosphere from vegetation and soils.

We have all heard and read statements on how seeing Earth from the space changes the astronauts. The vision of our beautiful blue globe without visible boundaries has stirred many emotions of peace and unity. However today it seems that there are boundaries of another kind becoming more visible from space.
According to John Grunsfeld, associate administrator for NASA's Science Mission Directorate and a former NASA astronaut, today one can see visible pockets where there is agriculture in some areas in stark contrast with struggling nations without means for irrigation as well as "shrinking pockets of wilderness." "You can see the boundaries of national parks. They look like somebody's drawn a dark line around them, with trees inside and nothing outside."
However, there is hope and all is not lost! Grunsfeld, is hoping for a rise in environmental awareness and activism as space flight becomes more available to the public. He believes seeing the only habitable planet of our system with the clear signs of destruction from above would inspire more people to want to make and keep Earth a better place to live.
