Images of Carbon Dioxide Emission Released by NASA

NASA captures and maps the carbon dioxide emission from space captured by NASA's Orbiting Carbon Observatory-2 or OCO-2 satellite.

According to the Science World Report, the image has been revealed that the carbon dioxide widespread across major urban areas and lesser pockets of high emissions derives from individual cities.

Over three major polluted regions have been studied by a team from the Finnish Meteorological Institute in Helsinki and provided the first direct examination. They were able to investigate the Central Europe, East Asia and Eastern U.S. Their study was led by Janne Hakkarainen and was published in Geophysical Research Letters.

However, the researchers were challenged because they have to untangle the current carbon dioxide emissions to the older ones. As the gas hangs around the atmosphere for over a century, the recent production of carbon emission by humans are only a small fraction of the overall carbon dioxide that are recorded by the OCO-2 as its review down at the Earth's surface.

"Currently, the background level of carbon dioxide in the atmosphere is about 400 parts per million, and human emissions within the past year may add only something like three parts per million to that total," said Janne Hakkarainen.
