Pattern of keeping weather and climate issues in the public mind
Alarmists use weather to promote global warming hoax
By Dr. Tim Ball Monday, July 7, 2008
Claims that recent severe weather and flooding in the US are proof of human CO2 impacts on global climate are scientific nonsense. They are part of a pattern of keeping weather and climate issues in the public mind.
My grandmother admonished me with, “Your sins will find you out.” It is a maxim that should now befall proponents of the false theory that human CO2 is causing global warming or climate change. Exposure rarely emerges from the original event, but as Watergate showed the coverup bares the truth.
Governments and large segments of society accepted the theory. Most bullied by use of fear but also their lack of knowledge and understanding was also exploited.
Now a combination of events are driving them to raise the threat level and make increasingly false claims. forcing a coverup. The world is cooling while CO2 levels continue to rise. In every record for any period in history temperature increases before CO2 not as assumed. Plans to implement carbon taxes to offset warming exacerbate soaring fuel prices. Effects of policies implemented to replace fossil fuels with biofuels are driving food and total living costs rapidly higher. People increasingly question the threats as a recent UK poll showed; “The majority of the British public is still not convinced that climate change is caused by humans - and many others believe scientists are exaggerating the problem, according to an exclusive poll for The Observer.” Proponents of the theory that humans are causing global warming or climate change have used fear to push their false belief. Now they’re experiencing fear as evidence shows they’re wrong and the public perceive a deception.
Robert Frost said, “There’s nothing I am afraid of like scared people.” Those who perpetrated possibly the greatest deception in human history that CO2 is causing global warming/climate change are scared. Events are driving them to extreme, unsubstantiated and even ridiculous claims and threats.
One of these was that sea level would rise, but it foundered when the two Nobel Peace Prize winners, the Intergovernmental Panel on Climate Change (IPCC) and Al Gore were in serious disagreement. Another was Arctic sea ice except it returned to long term normal levels last winter and NASA announced the one year anomaly was due to changes in wind patterns.
So they return to their central theme of convincing you that normal weather events are abnormal. An increase in severe weather is a persistent theme, especially in North America. Recently the U.S. Climate Change Science Program and the Subcommittee on Global Change Research issued a report with projected changes in weather and climate extremes in North America and U.S. territories.
Report co-chair Tom Karl, Ph.D., director of the National Oceanic and Atmospheric Administration (NOAA) National Climatic Data Center in Asheville, N.C said, “This report addresses one of the most frequently asked questions about global warming: what will happen to weather and climate extremes? This synthesis and assessment product examines this question across North America and concludes that we are now witnessing and will increasingly experience more extreme weather and climate events.”
Karl has a vested interest in this being true. It is the position of the IPCC and he cites the IPCC as the authoritative body. Internationally, the Intergovernmental Panel on Climate Change (IPCC), under the auspices of the United Nations (UN), World Meteorological Organization (WMO), and the United Nations Environment Program (UNEP), is the most senior and authoritative body providing scientific advice to global policy makers. Well he was a lead author for the Intergovernmental Panel on Climate Change (IPCC) Reports for 1990, 1992, 1995, a Coordinating Lead author and panel member of the 2001 Report and a Review Editor for Chapter 3 of the 2007 Report.

There are three major problems with what is being said. 1. The severe weather of this spring across the Northern Hemisphere was caused by cooler weather not warmer. 2. The IPCC and the NOAA positions that severe weather will increase with global warming is scientifically wrong. 3. The records show current weather extremes are well within long term natural variability.
Almost all global severe weather occurs in the middle latitudes between approximately 30° and 65° of latitude. Cyclonic storms, blizzards, severe thunderstorms and tornadoes are created where warm and cold air meets and that is most dramatic along what is generally known as the Polar Front. This world map of tornado zones illustrates the point.

Here is a simplified diagram of the division between the cold polar air and the warm tropical air.

Temperature contrast across the Polar Front is the greatest in a short distance in each hemisphere. This creates the strongest winds as illustrated by the location of the Jet Stream (more correctly called the Circumpolar Vortex) above the surface. It also means the formation of swirling low pressure systems or cyclones that in winter are blizzards. As the cold air advances it pushes up unstable bubbles of warm air to create heavy rain from large clouds. With enough force these can develop in to severe thunderstorms (cumulonimbus) and under certain conditions trigger tornadoes. These conditions occur most frequently across the central US in what is colloquially known as Tornado Alley.

1. Frequency and intensity of most severe weather is a direct function of the temperature contrast across the Polar Front. This spring the cold air stayed further south with the colder temperatures with the resulting severe weather and flooding across the central US.
2. IPCC Reports claim increased CO2 levels will make the Polar air warm more than the tropical air. If true, this will decrease the temperature contrast across the Front resulting in fewer storms and less severe weather.

3. The graph from the National Oceanographic and Atmospheric Administration (NOAA) shows that severe tornadoes were higher in the period from 1950 to 1975. Global temperatures were falling during that time. Since then frequency has decreased as the world warmed to 2000. Since then the world has cooled slightly and the pattern shows a slight increase in severe tornadoes.
This trend of severe weather is most likely to increase as the Earth continues to cool. Proponents of human caused climate change will claim it proves them right. They will continue their practice of claiming natural events as unnatural. Unless people understand the basic science they will continue the fraud and pressure politicians into even more damaging energy and environmental policies.
