Courtesy of Steven Hayward, over at Powerline, we look today at global warming, as defined by the alarmists, and we find a standard chart. We've seen plenty of these over the past decade and they normally look something like this.
OMG! We're all going to die. Look how fast temperatures are increasing. But, look at that vertical scale, it's a tiny range, representing about 3 degrees Fahrenheit. We would probably be better informed if we looked at the same data, using the normal range of temperatures we can expect to experience worldwide. So, lets do that in the second chart.
That doesn't look nearly as threatening, does it? I'm really amazed at how stable the average temps have been since 1880. We can probably attribute that tiny temperature increase to better record-keeping. It's certainly not indicative of climate change. In fact, it's not worth worrying about at all.
It's the same data, represented differently. Personally, I think that the second chart more accurately represents trends, which is to say that there is no trend at ll.
So, why are we having this discussion?
