A variety of reasons
Steven Trosper said in his Feb. 12 letter that global warning is a bunch of hype and hot air. Maybe so, because warm means moderate, and moderate means not excessive in amount, degree or force. Didn’t this arctic jet stream realize that we are living under the influence of global warming because of human pollution? Maybe the jet stream turned rogue.
What about any extremes of weather in the Middle Ages or in centuries before them when there weren’t any man-made land, ocean or air vehicles expelling chemical pollution into the air or factories belching chemical smoke out of their smoke stacks? This doesn’t mean we aren’t polluting with our man-made chemical, but there could be more than just this.
I can say that God can control the weather whenever He chooses, because it is written. There is an interesting story in the first two chapters of Job that tells what Satan is capable of doing with influencing human minds, the weather and even the human body if God allows it to be so.
There are powers that be that go beyond our three-dimension human life and our form of measurements. This fourth dimension really can’t be measured. Strange things can happen.
I can see three options for explaining extreme weather: Human pollution in this day and age, natural environment happenings or maybe a mixture of both, or someone controls the weather at times. Take your pick.
