Nasa rocket crash is big setback to knowledge of climate change

From The Times

The satellite, which was the first Nasa had dedicated to measuring the greenhouse gas from space, was expected to transform science's grasp of the 'carbon sinks' in soil, forests and oceans that absorb CO2 and keep much of it out of the atmosphere...Joanna Haigh [Physics], Professor of Atmospheric Physics at Imperial College, London, said: 'At present, when we calculate the carbon input and output of our planet, the numbers don't quite add up. In other words, there is some uncertainty about some of the major sources, and sinks, of carbon dioxide. This satellite would have helped remove that uncertainty.'
