We here at Republibot have long gone on record as being dubious about this whole "Global Warming" thing. Our individual opinions vary from outright disbelief that the phenomenon is actually happening to a grudging admission that something is going on, but we're unsure whether or not it has anything to do with us stupid humans. All three of us agree, however, that fear of Global Warming has been shamefully used to scare people out of their money and their votes. And it's been highly effective at that.
Back during the whole "Inconvenient Truth" thing, when every government agency was forced with the Stalinist reality of either agreeing with the ignorant hippies or being pilloried in public and having their funding cut, NASA went on record as saying that Gore was right, the world was getting warmer, we're all gonna' die, and it's all our fault, now can we please get back to working on that piece-of-crap space station that we don't even own, if it's ok with you?
Nowadays, with the Democrats firmly in office, NASA appears to feel a bit more secure about casting a dissenting voice (Make of that what you will), and have admitted that the Sun probably has a whole lot more to do with temperature on Earth than whether or not you drive a Prius and eat vegitarian.
Daily Tech addressed this in a recent article in which they state:
>>>While the NASA study acknowledged the sun's influence on warming and cooling patterns, it then went badly off the tracks. Ignoring its own evidence, it returned to an argument that man had replaced the sun as the cause current warming patterns. Like many studies, this conclusion was based less on hard data and more on questionable correlations and inaccurate modeling techniques.
The inconvertible fact, here is that even NASA's own study acknowledges that solar variation has caused climate change in the past. And even the study's members, mostly ardent supports of AGW theory, acknowledge that the sun may play a significant role in future climate changes.<<<
If you go to their site here http://www.dailytech.com/NASA+Study+Acknowledges+Solar+Cycle+Not+Man+Res... they've also got some charts that compare global temperatures to cycles of sunspot activity, and not surprisingly they more or less mirror each other.
Science Daily posted a longer version of basically the same story a few months back here http://www.sciencedaily.com/releases/2008/05/080512120523.htm
and of course if you want to tool around the NASA site to find the original sources for this info, this link'll get you started http://search.nasa.gov/search/search.jsp?nasaInclude=global+warming
Of course this info comes as no surprise to any of us here, since weather data we've been getting back from Mars over the past 30-odd years strongly suggests that Mars is having a mild bout of Global Warming as well. Clearly, we can't be responsible for that, since there's never been a single person on the Red Planet.
I should point out that we here at Republibot are not the kinds of people who automatically gainsay any environmental concerns. We do openly admit that there are many serious ecological threats and crises throughout the world - Deforestation, the reduction of Tropical Rain Forests, heavy metal dumping at sea, and of course the alarming increase in the ammount of lead in our atmoshphere over the last century. (The ammount of lead in the air is ONE THOUSAND times what it was 110 years ago!) These are real, clear-and-present dangers to humanity and the world itself. Our objection to the Global Warming mania is that even if it's real, it's a very minor problem that is part of a natural cycle we can't do anything about anyway - there have been 35 "Hot ages" in the last three million years, and obviously we couldn't have caused any of those - and all the money and attention blown on this non-issue is detracting more legitimate and immediate environmental concerns.
Or, to put that another way: We're not anti-environment, we're anti-frightening-the-gullible-public-to-make-a-few-bucks-and-ignore-real-problems. We've got a very strong anti-frightening-the-gullible-public-to-make-a-few-bucks-and-ignore-real-problems agenda here at the 'bot.
