The current year 2011 is a good example of what happens when global temperatures drop and we have cold and snowy winters that stretch well into spring. The current La Nina and the cold PDO brought colder temperatures and extra amount of snow during the past winter to many parts of North America, which means significant spring flooding like we just had in Central US and many parts of Canada.
The late and extra snow pack in the Rockies and the colder Pacific air, generally due to the colder North Pacific Ocean surface temperatures as measured by the PDO, also caused extra spring rain and even more flooding as well as severe tornadoes. As the quite cold air from the Rockies (due to the significant snow pack still in the mountains) meets the warm moist air coming from the Gulf of Mexico, severe and frequent tornadoes are spawned in the US tornado alley. This was also the pattern in the 1970’s.
Moreover, there could also be a loss of annual crops this year due to a shortened growing season from the extra wet soil and late planting because of the flooding and cold spring, This pattern could repeat itself many times in the decades ahead similar to the climate we had in the 1970’s. Both the Atlantic and Pacific oceans show strong indications of heading for cooler SST levels.
These alternating cold and warm phases typically last for 20-30 years, as reflected in our past climate records. We just came out of the warm phase and appear to be now headed for a cooler phase. The winters started to get cooler for some parts of the Northern Hemisphere already after 1998, but more noticeably and significantly in many regions including Europe and Asia during the last for 4 years.
Wasteful anti-global warming policies have resulted in badly needed funds being diverted towards very expensive and unsustainable green energy projects and carbon dioxide storage or sequestering. Without major government subsidies most of these projects would not be viable. Indeed their implementation worsened the financial situation of several poorer European nations. In some countries, fossil fuel plants are being shut down prematurely rather than being converted to cleaner fossil energies resulting in 100 % increase in energy costs due to the more expensive green energy replacements.
These very expensive policies to fight global warming have little effect on global temperatures, if any. These misguided policies divert valuable funds from other vital areas of our global life, like helping nations experiencing natural disasters, job creation, better health care, improved flood control, rebuilding homes and infrastructure after tornadoes and major flooding and extra food storage for emergencies. In my judgment this problem could get much worse in the coming years.
Like the Pacific Ocean, the North Atlantic Ocean is also cooling again and by 2015 we could begin to feel even cooler weather during the winter and spring especially along the North American eastern coasts and western Europe. Food and energy could be in short supply unless we all adjust our national and global focus from a non existing global warming threat to a much bigger and very current threat from global cooling for the next 20-30 years.
The events like cold and snowy winters, extra flooding and severe tornadoes have very little to do with man generated carbon dioxide or global warming as, to the contrary, the global temperatures have been cooler than normal this year and global temperatures have actually been declining since 2001 (see chart above).
