What is the most reputable AGW skeptic (non-Exxon funded) organization?

I'm at work and I don't have my sources linked to my work computer. But I know I have looked at the main NASA website and found articles about their research of how cloud cover effects the planet. I've looked at graphs and papers that show the oceans actually cooling and not warming up. I've paid close attention to the jet stream patterns this year. I also read some papers about sun spots and their cycles. None of the papers and articles I've read were funded by Exxon-Mobil.
