Hopefully there are fewer and fewer people in the industrialized world who are non-believers of anthropogenic (human) induced climate change. Maybe there are some who will never be convinced, especially those who have a vested interest in not believing it, or perhaps they are anti-leftist thinking, or just plainly anti-everything.
If you are one of those – please read the following intently, and if you are a believer then please read knowing that yet more evidence (if we need it) is going to come down the technical pipeline.
Over the last decade or more, NASA’s Earth Observing System (EOS) satellites have monitored the clouds, oceans, vegetation, ice, land and atmosphere, but the latest satellites promise even better information.
The NPOESS (National Polar-orbiting Operational Environmental Satellite System), now called Soumi NPOESS, has been monitoring Earth’s environment with keen scientific eyes since its launch in October 2011. The NASA satellite is also supported and used by the National Oceanic and Atmospheric Administration (NOAA) and the Department of Defense (DOD). Unlikely bed-fellows but beggars can’t be choosers and at least the data is likely to be mostly used for good of the planet (humans, animals, and the environment).
Soumi looks at cloud coverage, oceans health, and Earth’s vegetation coverage, looking for changes and helping climate scientists model our ever-changing world. It will also help improve weather prediction and identify future climate patterns.
The high tech hardware it carries includes an Advanced Technology Microwave Sounder (for global temperature and moisture measurements), a Cross-track Infrared Sounder (atmosphere monitoring), and an Ozone Mapping and Profiler Suite (the hole in Earth’s protective radiation shield that people seem to have forgotten about).
But there is more, it also carries a Visible Infrared Imaging Radiometer Suite (detecting and monitoring wildfires, ice and land changes) and, if that wasn’t enough already, a Clouds and Earth Radiant Energy System. This last instrument maps thermal radiation and checks on Earth’s energy balance with space, which will show definitively that Earth is absorbing more and more heat energy and warming up globally.
Soumi will measure snowstorms, droughts, floods, hurricanes and dust plumes (that affect climate models and weather predictions), soots, nitrogen dioxide and sulfur dioxide. Monitoring the vegetation will help measure the Earth’s carbon cycle and agricultural processes, helping predict food shortages. The global temperature record of the atmosphere, land and sea surface will be essential to know how quickly the Earth’s climate is changing.
With the existing plethora of earth observation satellites, both US, European and other countries are launching, soon there will be nowhere for scientifically-minded non-believers to hide. The big question then will be once again what to do politically about the hard facts staring people in the face. Procrastinate some more or start changing the way we live.
