The Unchanging Constant in Climate Change
Posted by Jerry on March 12, 2008
My readers in India know that we have had one of the coldest winters in several decades. In fact, Mumbai–which a city known to have only two seasons: summer and monsoon–experienced record low temperatures over the past few months. People in the city felt as if they were teleported to some arctic locale, being completely ill-prepared for the weather and having no warm clothes.
Apparently, the Indian subcontinental peninsula was not the only region to experience an abberrant drop in temperatures. According to this article in the DailyTech:
Over the past year, anecdotal evidence for a cooling planet has exploded. China has its coldest winter in 100 years. Baghdad sees its first snow in all recorded history. North America has the most snowcover in 50 years, with places like Wisconsin the highest since record-keeping began. Record levels of Antarctic sea ice, record cold in Minnesota, Texas, Florida, Mexico, Australia, Iran, Greece, South Africa, Greenland, Argentina, Chile — the list goes on and on.
The article goes on to say that the total amount of global cooling only this past year has been larger than the entire range of warm temperatures recorded in the past one hundred years. Note that this data suggests that the range of cooling that has occurred in this past year comes at the height of our industrial activity and population numbers.
All four major global temperature tracking outlets (Hadley, NASA’s GISS, UAH, RSS) have released updated data. All show that over the past year, global temperatures have dropped precipitously. The total amount of cooling ranges from 0.65C up to 0.75C — a value large enough to wipe out most of the warming recorded over the past 100 years. All in one year’s time. For all four sources, it’s the single fastest temperature change ever recorded, either up or down.
Scientists quoted in a past DailyTech article link the cooling to reduced solar activity which they claim is a much larger driver of climate change than man-made greenhouse gases. The dramatic cooling seen in just 12 months time seems to bear that out. While the data doesn’t itself disprove that carbon dioxide is acting to warm the planet, it does demonstrate clearly that more powerful factors are now cooling it.
So, is it time to return to the global cooling hysteria of the 1970s? Whatever the new fluctuating trend in global climate change, this one thing remains an unchanging constant–the environmentalists’ predilection for fear-mongering and human hatred.
