An alternative explanation for rising global temperatures is based on research by the Danish Space Center. They found that as solar activity increases, cloud formation on Earth is significantly diminished and temperature rises.
I once read an interesting study about skin cancer. Our skin, in response to sunlight, produces vitamin D. Sunblock prohibits the production of vitamin D. Exposure to the sun without the production of vitamin D may lead to skin cancer. Hence sunblock may actually be causing skin cancer, and not just sun exposure.
LOki, you know that GM just pays off the Danes... =P
Does it really matter what is causing global warming? No. Should we start preparing for it? Yes. Are Overpopulation and Peak-Oil vastly greater problems that we can do something about? Yes
This is the first pornsite I've found in years that I'd actually advertise to swarmers. When you first load it up, it looks just like every crappy scam site out there, except that it's real. It's huge, it's updated constantly, there's no spam, no popups, and no bullshit -- and it's completely free. When you sign up through that link above and respond to the confirmation email, I make a bit of loose change.
See what other swarmers have to say about it. People love this place, so I feel fine about sending you there and am confident you will enjoy boners.
