For most of the past two decades, a handful of climate change scientists have had the CIA's MEDEA (Measurement of Earth Data for Environmental Analysis) program as an ace in the hole: they could draw on classified info from spy satellites and subs to study global warming in extreme detail. However, they'll now have to make do with alternatives. The agency has shut down MEDEA, saying that its projects to study the security implications of climate change "have been completed." While the CIA says it'll still "engage external experts" on the subject, it won't be providing consistent access to its extremely accurate and rare data.
Whether or not the closure is a major problem depends on who you ask. There are doubts that the CIA is really a good leader in climate research, and it's safe to say that the organization typically has its hands full with the espionage business. However, there are also concerns that officials are cutting off access to accurate info at the very moment when things are getting complicated -- researchers need more data, not less. That may not be as much of an issue in the long run as non-classified satellites provide increasingly valuable findings, but the loss is still bound to hurt for at least a while.
