ScienceNow: Officials with NASA and the National Oceanic and Atmospheric Administration (NOAA) have decided to add a key climate sensor to a satellite scheduled to launch in 2010, ScienceNOW has learned. Scientists say the move will help ensure a continuous 22-year data set on climate change, which has been threatened by a Pentagon plan to strip six climate sensors from a key Earth-observing satellite (Science, 31 August 2007, p.1167).
