Warming 'pause' gives thought for scientists, sceptics
PARIS (AFP) - A slowdown in warming that has provided fuel for climate sceptics is one of the thorniest issues in a report to be issued by UN experts on Friday.
Over the past 15 years, the world's average surface temperature rose far slower than many climate models have predicted.
According to projections, global warming should go in lockstep with the ever-rising curve of heat-trapping carbon emissions.
But in recent years, warming has lagged. So, where has the missing heat gone? For climate sceptics, the answer is clear. Either the computer models used to project temperature rise are flawed, or man-made global warming is just a green scam, they say.
