Greenhouse Gases Now Seen From Space
New evidence from satellites orbiting the Earth has put an end to an doubts about whether greenhouse gases are actually increasing.
Until now, researchers depended on ground-based measurements and theoretical models to measure the increase. New sets of data taken from two satellites orbiting the Earth have now provided the first directly observable evidence of a rise in greenhouse gases.
?It?s the first time that we have seen observationally that these changes are really having an effect on the radiative forcing of the climate,? said Dr. Helen Brindley, an atmospheric physicist at Imperial College in London. Radiative forcing is the measure of the climate effects of greenhouse gases.
