The evidence shows serious deviations between CO2 claims, computer models and computer-generated forecasts and scenarios, on the one hand – and actual observations and measurements of temperature and weather, on the other hand. Historical and archaeological evidence (of major climate and weather changes and extremes) likewise do not support claims that allegedly stable climate conditions have suddenly been thrown into disarray by human greenhouse gas emissions.
Atmospheric carbon dioxide concentrations and observed temperature changes over the past century simply do not correlate nearly as well as necessary for proper scientific analysis. Similarly, historical evidence clearly demonstrates that there was a Medieval Warm Period (MWP) of great health, wealth and prosperity, during which temperatures were warmer than today’s, but with no anthropogenic carbon dioxide in the equation.
Archaeology and history also show that successful Viking settlements died out in Greenland after the MWP, as a significant 500-year-long period of global cooling set in. The coldest point of this Little Ice Age was the well-documented Maunder Minimum, when ice fairs were held on London’s frozen Thames River. Contemporary paintings of these frozen festivals still exist today.
Similar long-term periods, such as the Roman Warming, have likewise been documented, as have lengthy periods of droughts and floods in various ancient societies – to say nothing of major ice ages and interglacial periods that affected much of Europe and North and South America. Previous significant climatic changes are hardly rare events. However, for obvious reasons, the global warming advocacy faction does not want to discuss these historical periods.
Moreover, over the past decade, significant new scientific evidence has suggested that observed global warming can probably be explained largely or entirely by changes in solar activity and thus cosmic ray incidence on earth, consequent changes in cloud cover and atmospheric water vapour levels, periodic shifts in oceanic temperatures and currents, and other natural phenomena.
Why, then, do we witness repeated attempts to demonize and bury any hint that solar activity is a principal cause of observed global warming? Why do climate change alarmists seek to suppress evidence that there has been no statistically significant planetary warming since 1998? Why do so many Climategate 1.0 and 2.0 emails reflect much more private uncertainty among alarmist climate scientists than they have been willing to admit publicly?
These actions are much too close to the Galileo and French Revolution affairs for comfort.
Even worse, misguided government and corporate policies and actions worldwide – in response to the false science and high pressure tactics – will be highly detrimental to mankind, especially poor families that will be trapped in perpetual poverty, disease, malnutrition and premature death.
We can only hope that future generations will not group the Galileo, French Revolution and climate change eras as similar Dark Ages, when “establishment” zealots and easily inflamed crowds suppressed science and analytical truth.
Let us hope, instead, that at least some world leaders will have the courage to stand up at COP-17 and demand the kind of scientific rigour that brought so much enlightenment and progress over the centuries. Due diligence in Durban demands nothing less.
Only then will poverty be eradicated, and health and environmental conditions improve, for billions of people all over our planet.
