I'm not a climate scientist, just as I'm not a car mechanic. But when 97% of mechanics say my car is in bad shape, I fix the car rather than to put my children at risk by ignoring them.  Exactly so with climate peer-reviewed experts, at least 97% of whom say the current enormous spike in global warming  is primarily due to human activity. Please note the 'primarily', ie. not only. Do you have evidence of similar weight from similarly qualified and carefully-vetted scientists that show global warming is simply part of a natural cycle and that all the greenhouse gases our species has and is pumping into the atmosphere are neither here nor there.  My children and I will be mightily relieved to hear it! https://en.wikipedia.org/wiki/Surveys_of_scientists%27_views_on_climate_change
