So why is it so hard for the public to get hold of firm data? Why is all the information we get about Global Warming only in soundbite form?
You have GOT to be kidding me (I really and truly hope so).
There is freely available data for any and all who care to look. You get soundbites because most people DON'T care to look. And the majority who do care really couldn't understand the data if they did look. Why should they? One can toss out all sorts of data points on, say, engine performance but without the background knowledge to know what the data means, which conclusions they point to, what good is it?
But go on and follow the links just on this one page NASA provides:
http://gcmd.nasa.gov/Resources/pointers/meteo.html.
Data from NASA itself, the NOAA, DOD, DOE, USDA, EPA and links to state/regional climate organizations.
And these are just U.S. based links. No private or partisan organizations included.
