Well, isn't he right? Our "sin" is to take fossile fuels and burn them for our comfort and money-making releasing lots of carbon dioxide into the atmosphere and God's laws of nature "punish" us by reacting with global warming. HE plays by the eternal rules governing the universe, we don't and that has always been the easy way to failure.
I am way more annoyed by people disguising as rational beings denying everything science has to say on this. This guy at least admits that global warming is happening and we are the cause.
It is only that prayers won't save us. In this case they would be asking God to allow us to sin happily ever after by changing the rules. Now, what God would do that?
