Spencer: Global warming theory is in fact so malleable that it predicts anything. More cold, less cold. More snow, less snow. What a powerful theory. And what’s even more amazing is that climate change can be averted by just increasing your taxes. But what nobody ever reports on — because it would be boring — are the storms and severe weather events that haven’t happened. For example, U.S. tornado counts have been running below average, or even at record lows, in recent years. Amazingly, the low tornado activity has been blamed on climate change. So, too, have actual tornado occurrences! What a grand and gloriously useful theory global warming provides us. Is it any wonder that the public tends to be skeptical of what the experts tell us, when those experts continually change the narrative as their forecasts turn out wrong?
