Global Temperatures Expected To Rebound

Until recently, global temperatures were more than a degree Fahrenheit warmer when compared to the overall 20th Century mean. From August of 2007 through February of 2008, the Earth’s mean reading dropped to near the 200-year average temperature of 57 degrees.

We, Cliff Harris and Randy Mann, believe that the warming and even the cooling of global temperatures are the result of long-term climatic cycles, solar activity, sea-surface temperature patterns and more. However, Mankind’s activities of the burning of fossil fuels, massive deforestations, the replacing of grassy surfaces with asphalt and concrete, the ‘Urban Heat Island Effect,’ are making conditions ‘worse’ and this will ultimately enhance the Earth’s warming process down the meteorological roadway in the next several decades.

From the late 1940s through the early 1970s, a climate research organization called the Weather Science Foundation of Crystal Lake, Illinois, determined that the planet’s warm, cold, wet and dry periods were the result of alternating short-term and long-term climatic cycles. These researchers and scientists also concluded that the Earth’s ever-changing climate likewise has influenced global and regional economies, human and animal migrations, science, religion and the arts as well as shifting forms of government and strength of leadership.

Much of this data was based upon thousands of hours of research done by Dr. Raymond H. Wheeler and his associates during the 1930s and 1940s at Kansas State University. Dr. Wheeler was well-known for his discovery of various climate cycles, including his highly-regarded ‘510-Year Drought Clock’ that he detailed at the end of the ‘Dust Bowl’ era in the late 1930s.

During the early 1970s, our planet was in the midst of a colder and drier weather cycle. Inflationary recessions and oil shortages led to rationing and long gas lines at service stations worldwide. The situation at that time was far worse than it is now, at least for the time being.

The Weather Science Foundation also predicted, based on these various climate cycles, that our planet would turn much warmer and wetter by the early 2000s, resulting in general global prosperity. They also said that we would be seeing at this time widespread weather ‘extremes.’ There’s little doubt that most of their early predictions came true.

Our recent decline in the Earth’s temperature may be a combination of both long-term and short-term climate cycles, decreased solar activity and the development of a strong long-lasting La Nina, the current cooler than normal sea-surface temperature event in the south-central Pacific Ocean. Sunspot activity in the past 18 months has decreased the lowest levels since ‘The Little Ice Age’ ended in the mid-to late 1800s. This "cool spell," though, may only be a brief interruption to the Earth’s overall warming trend. Only time will tell.

Based on these predictions, it appears that much warmer readings may be expected for Planet Earth, especially by the 2030s, that will eventually top 1998's global highest reading of 58.3 degrees. It’s quite possible we could see an average temperature in the low 60s. Until then, this ‘cooling period’ may last from just a few months to as long as several years, especially if sunspot activity remains very low.

We at Harris-Mann Climatology, www.LongRangeWeather.com, believe that our prolonged cycle of wide weather ‘extremes,’ the worst in at least 1,000 years, will continue and perhaps become even more severe, especially by the mid 2010s. We should see more powerful storms, including major hurricanes and increasing deadly tornadoes. There will likewise be widespread flooding, crop-destroying droughts and freezes and violent weather of all types including ice storms, large-sized hail and torrential downpours.

We are already seeing on virtually every continent an almost Biblical weather scenario of increasing droughts and floods. In both the southwestern and southeastern corners of the U.S, there are severe water shortage problems associated with chronic long-term dryness. In some cases, the water deficits are the worst in at least 400 years.

Dr. Wheeler also discovered that approximately every 102 years, a much warmer and drier climatic cycle affects our planet. The last such ‘warm and dry’ peak occurred in 1936, at the end of the infamous ‘Dust Bowl’ period. During that time, extreme heat and dryness, combined with a multitude of problems during the ‘Great Depression,’ made living conditions practically intolerable.

The next ‘warm and dry’ climatic phase is scheduled to arrive in the early 2030s, probably peaking around 2038. It is expected to produce even hotter and drier weather patterns than we saw during the late 1990s and early 2000s.

But, we should remember, that the Earth’s coldest periods have usually followed excessive warmth. Such was the case when our planet moved from the Medieval Warm Period between 900 and 1300 A.D. to the sudden ‘Little Ice Age,’ which peaked in the 17th Century.

By the end of this 21st Century, a big cool down may occur that could ultimately lead to expanding glaciers worldwide, even in the mid-latitudes. We could possibly see even a new Great Ice Age. Based on long-term climatic data, these major ice ages have recurred about every 11,500 years. Well, you guessed it. The last extensive ice age was approximately 11,500 years ago, so we may be due. Again, only time will tell.
