In the geological past, there have been six major ice ages. During five of these six ice ages, the atmospheric carbon dioxide content was higher than at present. It is clear that the colorless, odorless, non-poisonous gas called carbon dioxide did not drive past climates. Carbon dioxide is plant food, not a pollutant.
Humans have adapted to live on ice sheets, deserts, mountains, tropics, and sea level. History shows that humans and other organisms have thrived in warm times and suffered in cold times.
In the 600-year long Roman Warming, it was 4ºC warmer than now. Sea level did not rise and ice sheets did not disappear. The Dark Ages followed, and starvation, disease, and depopulation occurred. The Medieval Warming followed the Dark Ages, and for 400 years it was 5ºC warmer. Sea level did not rise and the ice sheets remained. The Medieval Warming was followed by the Little Ice Age, which finished in 1850. It is absolutely no surprise that temperature increased after a cold period.
Unless I have missed something, I am not aware of heavy industry, coal-fired power stations, or SUVs in the 1,000 years of Roman and Medieval Warmings. These natural warmings are a dreadful nuisance for climate alarmists because they suggest that the warming since 1850 may be natural and may not be related to carbon dioxide emissions.
There was warming from 1860 to 1880, 1910 to 1940, and 1976 to 1998, with intervening periods of cooling. The only time when temperature rise paralleled carbon dioxide emissions was 1976-1998. The other warmings and coolings in the last 150 years were unrelated to carbon dioxide emissions.
Something is seriously wrong. To argue that humans change climate requires abandoning all we know about history, archaeology, geology, astronomy, and solar physics. This is exactly what has been done.
The answer to this enigma was revealed last week. It is fraud.
Files from the UK Climatic Research Unit were hacked. They show that data was massaged, numbers were fudged, diagrams were biased, there was destruction of data after freedom of information requests, and there was refusal to submit taxpayer-funded data for independent examination.
Data were manipulated to show that the Medieval Warming didn’t occur, and that we are not in a period of cooling. Furthermore, the warming of the 20th century was artificially inflated.
This behavior is that of criminals and all the data from the UK Hadley Centre and the US GISS must now be rejected. These crooks perpetrated these crimes at the expense of the British and U.S. taxpayers.
The same crooks control the IPCC and the fraudulent data in IPCC reports. The same crooks meet in Copenhagen next week and want 0.7% of the Western world’s GDP to pass through an unelected UN government, and then on to sticky fingers in the developing world.
You should be angry. Very angry.
