Behind the present pause in global warming
The temperature departure from the 1951-1980 average over the last 12 years. Trend is about flat (slightly up). (Data from NASA) Has global warming stopped since the turn of the millennium? Yes – if you examine the data in a vacuum. But has the warming pressure on the atmosphere from man-made greenhouse gases stopped? No – not at all. A closer look at the data bears that out.
It’s easy to glance at a temperature chart of the last 12 years (to the right) and draw the conclusion warming has slowed or stopped. That’s what renowned environmental scientist James Lovelock did and he’s now told MSNBC he’s backed away from his dire concerns about global warming.
“We were supposed to be halfway toward a frying world now,” he said. “The world has not warmed up very much since the millennium.”
What the author is saying is that the temperature data doesn’t conform to the theory, so we should ignore the data and stick with theory.
