I'm using scientific sources not regurgitated journalistic jingoism. For instance:

Hello Ed30.....I've taken the time to do a little check on the site you referenced as your "scientific source" and found some interesting facts. The site was founded and is run by the Idso family of Arizona. They are strong skeptics of the global warming theory with their funding coming from big oil (Exxonmobile) and The Western Fuels Association. It should be noted that their key supporting skeptical evidence has been proven invalid by modern science.
Here's more info...
Center for the Study of Carbon Dioxide and Global Change
The Center for the Study of Carbon Dioxide and Global Change is a non-profit organization based in Arizona. Its stated purpose is to "disseminate factual reports and sound commentary on new developments in the world-wide scientific quest to determine the climatic and biological consequences of the ongoing rise in the air's CO2 content." The center publishes CO2 Science Magazine.
The centre was founded and is run by Craig D Idso, son of Sherwood B Idso, and by Sherwood's (other) son Keith E Idso. They came from backgrounds in agriculture, and became involved in the debate over global warming through their study of plant response to elevated CO2 levels and carbon sequestration. The Center is generally critical of the position of the IPCC and is of a strongly skeptical bent - proclaiming There Has Been No Net Global Warming for the Past 70 Years. Note that two key claimed pieces of supporting evidence - the lack of warming in the Satellite temperature record and the balloon record - are no longer considered valid, following corrections to the observational data. The surface instrumental temperature record also shows warming over this period.
For some time in 2005, the website was no longer free, because grants and donations to the site had declined dramatically [1]. As of 2006 it is free again, though there is a "premium login".
The Center has links to the fossil fuel industry, both through personnel and funding.
According to Center for Science in the Public Interest, the Center for the Study of Carbon Dioxide and Global Change received $10,000 from ExxonMobil in 2001. [2]
StopExxon.org reports Center for the Study of Carbon Dioxide and Global Change has received $65,000 from ExxonMobil between 1998 and 2003. [3]
The Center works with the Greening Earth Society, a front group of the Western Fuels Association.
Both Idso brothers have been on the Western Fuels payroll at one time or another.
The Center produces a weekly online science newsletter called CO2 Science Magazine.
Do you suppose the Idso's sole purpose of global warming skepticism is to support their livehood through grants, donations, and the income from their weekly magazine? I don't have proof of that but I have read that Big Oil pays a lot of money to their global warming skeptics.
