Could climate change be caused, not by "greenhouse gases", but instead by the sun varying it's distance also, as it spirals around the earth? I'm guessing 60 years for a complete cycle. At 100,00 miles per year, it would move away 3 million additional miles in 30 years, then move back over the next 30 years to repeat the cycle. Could God do something like that?
