NASA spent over $100 million on a satellite to investigate climate change. It's all ready to launch. But NASA mothballed it instead. A DeSmogBlog exclusive investigation into NASA's DSCOVR climate station
What happened? How could the US government possibly justify killing DSCOVR given the importance of climate change and after over 90% of the project expenses had already been incurred? What role did petty partisan politics play in this? Did the oil lobby have any influence on this decision?
... The Earth’s temperature is a delicate balance between the amount of energy retained by the atmosphere and the amount being reflected back into space. This second number is called “albedo” and it is vitally important to scientists trying to develop reliable computer models on our changing climate. DSCOVR would provide vastly improved measurements of the Earth’s albedo because from L1, it would be able to continuously observe the entire sunlit disc of our planet.
Interestingly, a common complaint of climate change deniers has been that the satellite data used to develop climate models is unreliable. DSCOVR would go a long way to settling whatever honest debate remained about the reliability of those models.
Considering that these climate models are now driving enormous public policy decisions, one would think that DSCOVR would be a top priority.
... The French were so alarmed by the foot dragging by NASA they offered to send DSCOVR into space themselves at a greatly reduced cost. The Ukranian government even offered to launch DSCOVR for free aboard a Tsyklon IV rocket – the most reliable launch vehicle in the world.
