Would a global warming really be that bad?
Some folks are incredulous about the title of my new book, Climate of Corruption: Politics and Power Behind the Global Warming Hoax
. How can I possibly doubt that global warming is real? Now, in the interest of full disclosure, I am obliged to concede that they are correct, and that such evidence truly does exist.
Yes, there is no doubt about it. The planet is experiencing a siege of abnormally high temperatures. This has now been going on for 15,000 to 18,000 years, a life-friendly period known as an interglacial cycle. During glacial ages that exist about 90% of the time, our Northern Hemisphere is mostly covered with ice up to several miles thick. Records of these alternating glacial and interglacial fluctuations reveal the near regularity of an electrocardiogram over many hundreds of thousands of years … beginning long before the man-made inventions of agriculture, smokestacks, SUVs and carbon offset trading scams.
And just how abnormally warm is it now?
Let's consider some "recent" comparisons. Temperatures are probably about the same today as during a "Roman Warm Period" slightly more than 2,000 years ago, and much warmer than the "Dark Ages" that followed. They are cooler than the "Medieval Warm Period" about 1,000 years ago when Eric the Red and his Icelandic Viking tribe settled on grasslands of Greenland's southwestern coast, and much warmer than about 400 years ago when the Northern Hemisphere plunged into depths of a "Little Ice Age" (not a true Ice Age). Near the end of that period Washington's army suffered brutal cold at Valley Forge (1777), and Napoleon's, a frigid retreat from Russia (1812).
More recent temperature variations have been relatively much more stable and moderate. The past century witnessed two distinct warming periods, one occurred from 1900-1945, and another from 1975-1998. About half of that total warming occurred before the mid-1940s. And while CO2 levels have continued to rise, there hasn't been statistically significant warming since 1998 (the end of a strong El Nino season).
Those who pay honest attention to long-term climate patterns will note that atmospheric CO2 concentration fluctuations do not lead, but typically follow, temperature changes. That's because oceans are huge CO2 sinks, absorbing CO2 as they cool, and releasing CO2 as they warm up. (When you open a carbonated beverage you experience the same phenomenon. If the beverage is cold, it retains CO2. If it is warm, it releases CO2 and sprays all over.) These temperature shifts are heavily influenced by entirely natural ocean cycle fluctuations that affect heat transfer patterns from the tropics. In the Arctic these oscillations occur about every 60 to 70 years.
Short- and long-term solar fluctuations have important influences too. Decadal and longer changes in sunspot activity impacting warming and cooling cloud cover patterns are now being recognized as an important factor. Other solar changes occurring at approximate 1,500 year intervals also influence climate. Greenland, for example, has experienced an estimated 600 of these cycles over the past million years.
Antarctica has a somewhat separate and special climate system from other parts of the globe. And while surface stations show slight warming for its Western Peninsula, temperatures over most of the continent have been stable or cooling since 1960.
Our perceptions about warming and cooling trends tend to depend upon where we happen to reside and the time frame we experience for reference. During July 2010, residents of New England witnessed the tenth warmest temperatures recorded during that month in about a century, while those in southwestern U.S. states registered below normal. Simultaneously, Los Angeles broke a coldest July day record set in 1926, Australia since 1966, and the southern cone of South America saw the coldest July in a half century. Freezing temperatures in eastern Bolivia (normally above 68 degrees Fahrenheit) killed millions of fish in three major rivers, and the freeze was viewed as an environmental catastrophe.
This picture is far different from the really scary "climate crisis" reports we constantly receive in the media. And this circumstance isn't the first time prominent news producers, supported by "scientific experts", have warned about impending doom. An October 7, 1912 Los Angeles Times feature proclaimed "Fifth Ice Age is on the Way: Human Race Will Have to Fight for Existence in Cold". By August 9, 1923 the situation had become desperate, prompting the Chicago Tribune to declare "Scientists Say Arctic Ice Will Wipe Out Canada". Then, after a short period when the world appeared to be warming again, the March 1, 1975 cover of Science News magazine depicted New York City being swallowed by a glacier. The New York Times followed with a headline story "Scientists Ponder Why World's Climate is Changing: A Major Cooling Widely Considered to be Inevitable". The prestigious National Academy of Sciences agreed: global cooling was a real threat.
Just slightly more than a decade later, media headlines reported a new and opposite crisis- thanks to theater carefully staged by then-Senator Al Gore's 1988 Committee on Science, Technology and Space hearings. The star actor was NASA Godard Institute for Space Studies director James Hansen who claimed with 99 percent certainty that temperatures were rising due to a human-influenced "greenhouse effect". The concern was linked to a particularly warm summer that year in some U.S. regions.
