The Economist has been fairly consistent in its stand that carbon dioxide emissions from man-made sources are the chief cause of global warming. But in an editorial this week, it sounds less certain.
Global warming predictions haven’t panned out as predicted in the past decade, but the why is a bit fuzzy, the magazine admits.
Greenhouse gas emissions have soared during the past 15 years, the magazine notes, with 100 billion tons of carbon having been added to the atmosphere between 2000 and 2010. Still, both air and ground temperatures during that time have remained virtually unchanged.
In fact, the editorial notes, surface temperatures have been at the bottom of the projected range of various models since 2005. If they remain flat, they will actually begin to fall below projections shortly.
