Ten facts about climate change
1. Climate has always changed, and it always will. The assumption that prior to the industrial revolution the Earth had a “stable” climate is simply wrong. The only sensible thing to do about climate change is to prepare for it.
2. Accurate temperature measurements made from weather balloons and satellites since the late 1950s show no atmospheric warming since 1958. In contrast, averaged ground-based thermometers record a warming of about 0.40 C over the same time period. Many scientists believe that the thermometer record is biased by the Urban Heat Island effect and other artefacts.
3. Despite the expenditure of more than US$50 billion dollars looking for it since 1990, no unambiguous anthropogenic (human) signal has been identified in the global temperature pattern.
4. Without the greenhouse effect, the average surface temperature on Earth would be -180 C rather than the equable +150 C that has nurtured the development of life.
Carbon dioxide is a minor greenhouse gas, responsible for ~26% (80 C) of the total greenhouse effect (330C), of which in turn at most 25% (~20C) can be attributed to carbon dioxide contributed by human activity. Water vapour, contributing at least 70% of the effect, is by far the most important atmospheric greenhouse gas.
5. On both annual (1 year) and geological (up to 100,000 year) time scales, changes in atmospheric temperature PRECEDE changes in CO2. Carbon dioxide therefore cannot be the primary forcing agent for temperature increase (though increasing CO2 does cause a diminishingly mild positive temperature feedback).
6. The UN Intergovernmental Panel on Climate Change (IPCC) has acted as the main scaremonger for the global warming lobby that led to the Kyoto Protocol. Fatally, the IPCC is a political, not scientific, body.
Hendrik Tennekes, a retired Director of Research at the Royal Netherlands Meteorological Institute, says that “the IPCC review process is fatally flawed” and that “the IPCC wilfully ignores the paradigm shift created by the foremost meteorologist of the twentieth century, Edward Lorenz“.
7. The Kyoto Protocol will cost many trillions of dollars and exercises a significant impost those countries that signed it, but will deliver no significant cooling (less than .020 C by 2050, assuming that all commitments are met).
