How does a spaceborne instrument like AIRS extract carbon dioxide from Earth's atmosphere, and what is its data revealing?

A NASA/university team has published the first global satellite maps of the key greenhouse gas carbon dioxide in Earth's mid-troposphere, an area about 8 kilometers, or 5 miles, above Earth. The team's study reveals new information on how carbon dioxide, which directly contributes to climate change, is distributed in Earth's atmosphere and moves around our world.

Carbon dioxide (CO2) is the principal man-made greenhouse gas and the primary atmospheric component of the global carbon cycle. Precise ground-based measurements of CO2 made since the late 1950s indicate that the atmospheric CO2 concentration has increased from ~310 to over 380 parts per million (ppm) over this period [1].

A new study, co-funded by NASA, has identified a link between a warming Indian Ocean and less rainfall in eastern and southern Africa. Computer models and observations show a decline in rainfall, with implications for the region

Scientists studying variations in tropical heat and rainfall since the mid-1980s have found a strong link between warm periods and a rise in the frequency of the most extreme downpours.
The observed rise in the heaviest tropical rains is about twice that produced by computer simulations used to assess how human-caused global warming could change rainfall, said the researchers.

Ranchi, Aug. 3: For 16 students of city-based Sapphire International School, flying a space craft at Nasa's space research centre at Albama in the US will become a reality this October.

This is the first time that state students are going to Nasa. The school management is currently preparing the final list of students from Class III to VII, who will be chosen for the trip.

The students, aged nine-14 years, will leave on October 5 with their principal Anupama Singh and a science teacher.

Alleging that the Red Indian Horned Owl, locally known as hoodoo, is being sold to NASA for facilitating research works, People for Animals, a non-government organisation working against cruelty against animals, has decided to move Chief Minister Tarun Gogoi urging the latter to initiate measures for protection of the endangered species.

Sangeeta Goswami, president of People for Animals, Assam chapter, alleged that the endangered birds are being sold for Rs 25 lakh each in the international market, which, of late, has caught the attention of animal activists worldwide.
