Hi! I'm writing from TheScienceDesk at TheNewsRoom. I agree with what the others are saying here. As with other views, we need confirmation that ours is a valid one. Unfortunately, global warming sites will always have leanings, unless it's a really open forum. Nevertheless, you will still see the opinions of both sides in most sites whether these are pro or anti anthropogenic global warming. I suggest that you go to news sites that simply give the news as they come. The more you read, the more informed you will be and the better you'll be able to form conclusions or simply theorize about what's really happening to the Earth.
Here's a link to TheNewsRoom which I think might interest you. It's about how math is used to asses the impact of solar cycles on the Earth's atmosphere: http://www.thenewsroom.com/details/561532?c_id=wom-bc-ar
We already have a group of users who have a genuine interest in global warming who have found news that they have successfully used in their sites. If you're interested, you may email jtowns@voxant.com. We'll be happy to accommodate your inquiries.
