Earth’s climate changes are extraordinarily complex phenomena. They represent decadal, to millennial, to epochal changes in weather patterns as nature continuously attempts to compensate for solar heating imbalances in and between the atmosphere and oceans.
Nature’s attempts to restore heat balance take place under the complicating influences of the Earth’s inclined daily rotation, movement and release of heat stored in the oceans, aerosol production by many natural processes, water and carbon dioxide concentrations in the atmosphere, and periodically changing orbital position and orientation relative to the sun. In spite of all these variables and more, the Earth currently controls its temperature in a very narrow range as shown by satellite measurements of the temperature of the lower atmosphere (troposphere) since 1979.
Global surface and near surface temperatures have risen about half a degree Centigrade (about 0.9 degree Fahrenheit) each 100 years since the minimum temperatures of the Little Ice Age in 1660. Multi-decade intervals of more rapid warming and cooling have occurred during this current, centuries-long general warming trend as they have for over 10,000 years since the last major ice age.
Indeed, by the end of the 17th century, glaciers had advanced over valley farmlands cultivated as those same glaciers receded during the preceding Medieval Warm Period (about 800-1300). Since the last major ice age, decades long periods of warming and cooling have been superposed on longer cycles, the longest repeating about every 1500 years.
All of this has occurred without any significant human activity. Cooling between 1935 and 1975 and since 2000, and warming between 1975 and 1995 have been the most recent such variations and correlate strongly with variations
in solar activity.
In contrast to these facts, climate change assumptions and computer modeling, rather than real-world observations, underpin the government’s efforts to restrict American liberties and confiscate trillions of dollars of American income in the name of “doing something” about climate change. The scientific rationale behind this proposed massive intrusion into American life requires more than a “consensus” of like-minded climate analysts and bureaucrats. It needs to be right.
Recent disclosures and admissions of scientific misconduct by the United Nations and advocates of the human-caused global warming hypothesis shows the fraudulent foundation of this much-ballyhooed but non-existent scientific consensus about climate.
