NASA is constantly "fixing" earth through the various earth science missions. I'll recopy this from a thread I did in the environment folder. Five launches coming up 2014. OCO-2 and CATS are somewhat global warming science specific, while the other 3 have broad applications.
NASA Set for a Big Year in Earth Science - NASA Jet Propulsion Laboratory
Feb 27. Global Precipitation Measurement (GPM) Core Observatory. Detailed global precipitation measurment. Launch by JAXA (the Japanese Space Agency).
Jun 6. ISS-RapidScat. Detailed global wind measurements. To be installed on ISS. Launch from Cape Canaveral on SpaceX Falcon 9, ISS resupply mission.
Jul 1. Orbiting Carbon Observatory - 2 (OCO-2). The first OCO satellite was lost in a launch failure in 2009. Examines carbon sources and sinks. Launch from Vandenberg on Delta II.
Sep 12. Cloud-Aerosol Transport System (CATS). Like the name says, looking at clouds and aerosols. Similar system, Glory satellite, lost in a launch failure in 2011. CATS to be installed on ISS. Launch from Cape Canaveral on Falcon 9, ISS resupply mission.
November. Soil Moisture Active Passive (SMAP) mission. Like the name says, soil moisture mapping. Launch from Vandenberg on Delta II.
There's a new generation weather satellite launch in early 2017, JPSS-1. Cameras in visible and infrared, microwave radar for cloud height mapping, spectrometer, ozone mapper. This is important because the USA is currently down to one polar-orbiting weather satellite, the Suomi NPP, which has a design life that takes it to 2016. Let's hope it lasts longer. It's a story of bureaucratic struggles, where NASA, NOAA and the Air Force all wanted the other guys to be the ones responsible for launching a mundane civilian weather satellite. (The military has their own weather satellites, but they don't share.)
