Because it's monumental waste of time? Because the same people keep asking for the same information over and over again? Nah, global conspiracy is funner. Yes, funner.
Or how about because NASA's own data discredits it?
LOL, this is the stuff you won't hear from the news. If you actually take the time to research it (I did), it's amazing how baseless their claims are. I was particularly surprised when I ran across nasa.gov websites which discredit the entire theory with historical satellite data. Your global warming "scientists" like to use ground-based (IE: fluctuating) temperature methods versus using satellites that take temperatures based on the atmosphere as a whole. NASA's data shows we've been in a long cooling trend. But again, you actually have to research it for yourself instead of blindly taking what they tell you.
Did you know increases in carbon always equate to cooling trends? Again- not something the news will tell you. It's pseudo-science.
It's a run for money, nothing more. Global cooling just stopped being popular back in the 90s, after everyone called their BS "science". A decade later, the same scare tactic run for money exists today in global warming.
Part of me wonders, as well, when these "scientists" will discover the obvious: the earth has warming and cooling cycles.
Something like this falls into the same category. It's a run for money. NASA wants to become relevant, and relevant entities receive money.
This stuff isn't unusual, it happens. It's normal. Those cycles of 11 years you heard about? Do you happen to remember in 2002 all the electronics dying off from the last one? No? Didn't think so. What about in 1991??? No? Didn't think so.
