You know in the time of the dinosaurs (reptiles) the climate had to be extremely warm for most to survive. Fossils have been found on every inhabited continent on the planet. So, can someone who actually believes in mankind-caused Global Warming please explain why it was so hot back then? Did dinosaurs emit so much flatulence that it kept Earth warm/hot (roll eyes)?
NASA collects the data (with its impressive gadgets) that gets turned into research by groups like NOAA. Understanding a plant or moon's weather and atmospheric conditions are kind of important to explore it. NASA has the convenience of studying this plant's weather to help prepare it. These guys know what they're doing.
Judas, that link is pure liberal nonsense. Producing fancy graphs and bull sh*t "facts" about ancient history is ridiculous. You and your liberal friends seem to know as much about Earth's history as God. After all, you guys were here for the last 300 million years to record temperatures at every major location, right?
