Global warming, global cooling, climate change, all of these do occur. As an earth scientist we see from the past that climate is cyclical and these things have been going on from the beginning of time and will continue long after we’re gone. We’ve all heard of 100 or 79 year floods, droughts, ice ages, etc. the earth rotates around the sun on an elliptical orbit and sometimes we’re closer to the sun than others. The politicization is merely a ploy to make them rich.
