First, NASA says climate change is very real indeed.  If you respect NASA, change your position.  

Second,  your link is to what is commonly known as an internet 'echo chamber' - the usual group of (Republican) climate change deniers telling each other they know more than the world's top scientists.  Comparable to the tobacco industry hollering there's no link between smoking and cancer. 

All you can offer to justify climate change denial is a website featuring luminaries like Sean Hannity, Rush Limbaugh, and Ann Coulter.  This is the crew you prefer to the best scientific minds and academies around the world???? 

If this is all you have to offer, I rest my case.
