THE STARK headline appeared just over a year ago. “2007 to be ‘warmest on record,’ ” BBC News reported on Jan. 4, 2007. Citing experts in the British government’s Meteorological Office, the story announced that “the world is likely to experience the warmest year on record in 2007,” surpassing the all-time high reached in 1998.
But a funny thing happened on the way to the planetary hot flash: Much of the planet grew bitterly cold.
Now all of these may be short-lived weather anomalies, mere blips in the path of the global climatic warming that Al Gore and a host of alarmists proclaim the deadliest threat we face. But what if the frigid conditions that have caused so much distress in recent months signal an impending era of global cooling?
“Stock up on fur coats and felt boots!” advises Oleg Sorokhtin, a fellow of the Russian Academy of Natural Sciences and senior scientist at Moscow’s Shirshov Institute of Oceanography. “The latest data . . . say that earth has passed the peak of its warmer period, and a fairly cold spell will set in quite soon, by 2012.”
Sorokhtin dismisses the conventional global warming theory that greenhouse gases, especially human-emitted carbon dioxide, is causing the earth to grow hotter. Like a number of other scientists, he points to solar activity – sunspots and solar flares, which wax and wane over time – as having the greatest effect on climate.
“Carbon dioxide is not to blame for global climate change,” Sorokhtin writes in an essay for Novosti. “Solar activity is many times more powerful than the energy produced by the whole of humankind.” In a recent paper for the Danish National Space Center, physicists Henrik Svensmark and Eigil Friis-Christensen concur: “The sun . . . appears to be the main forcing agent in global climate change,” they write.
Given the number of worldwide cold events, it is no surprise that 2007 didn’t turn out to be the warmest ever. In fact, 2007′s global temperature was essentially the same as that in 2006 – and 2005, and 2004, and every year back to 2001. The record set in 1998 has not been surpassed. For nearly a decade now, there has been no global warming. Even though atmospheric carbon dioxide continues to accumulate – it’s up about 4 percent since 1998 – the global mean temperature has remained flat. That raises some obvious questions about the theory that CO2 is the cause of climate change.
Just last month, more than 100 scientists signed a strongly worded open letter pointing out that climate change is a well-known natural phenomenon, and that adapting to it is far more sensible than attempting to prevent it. Because slashing carbon dioxide emissions means retarding economic development, they warned, “the current UN approach of CO2 reduction is likely to increase human suffering from future climate change rather than to decrease it.”
Climate science isn’t a religion, and those who dispute its leading theory are not heretics. Much remains to be learned about how and why climate changes, and there is neither virtue nor wisdom in an emotional rush to counter global warming – especially if what’s coming is a global Big Chill.
