It’s one solution to global warming: let our environmental satellites "collapse." From a CNN story:
Scientists warn that the consequences of neglecting Earth-observing satellites could have more than academic consequences. It is possible that when a big volcano starts rumbling in the Pacific Northwest, a swarm of tornadoes sweeps through Oklahoma or a massive hurricane bears down on New Orleans, the people in harm’s way — and those responsible for their safety — will have a lot less information than they’d like about the impending threat.
To be fair, this is not a new issue in observational science. In his autobiography ("Rewards and Penalties of Monitoring the Earth") the man credited with discovering global warming, Charles Keeling, repeatedly describes scrambling desperately for funding. Had the funding been interrupted, the famous Mauna Kea observatory he helped launch would have had to shut down, with serious, perhaps catastrophic consequences for our understanding of atmospheric chemistry.
But that’s exactly what we’re facing right now:
Landsat, a series of satellites that have provided detailed images of the ground surface for more than 30 years, is in danger of experiencing a gap in service. Landsat 7, launched in April 1999, is scheduled to be replaced by a next-generation satellite in 2011. But if the existing satellite fails before that date and NASA has not developed a contingency plan, scientists, land managers and others who depend on Landsat images could be out of luck.
