Man-made global warming would be nice, but Harvard researchers suggest our early optimism (or, more generally, alarmism) may be overstated. According to their research, we have yet to warm the planet to the levels seen during the Dark Ages.
According to the British Daily Telegraph, "Claims that man-made pollution is causing 'unprecedented' global warming have been seriously undermined by new research which shows that the Earth was warmer during the Middle Ages. ... A review of more than 240 scientific studies has shown that today's temperatures are neither the warmest over the past millennium, nor are they producing the most extreme weather - in stark contrast to the claims of the environmentalists. "
With the onset of the Little Ice Age around 1300, one researcher observes, "the temperature started to drop, harvests failed and England's vine industry died. It makes one wonder why there is so much fear of warmth."
A comeback for British wine? No wonder the UN wants to fight global warming.
