Copenhagen Climate Challenge. An open letter to Secretary-General of United Nations.
We the undersigned, being qualified in climate-related scientific disciplines, challenge the UNFCCC and supporters of the United Nations Climate Change Conference to produce convincing OBSERVATIONAL EVIDENCE for their claims of dangerous human-caused global warming and other changes in climate. Projections of possible future scenarios from unproven computer models of climate are not acceptable substitutes for real world data obtained through unbiased and rigorous scientific investigation.
Specifically, we challenge supporters of the hypothesis of dangerous human-caused climate change to demonstrate that:
- Variations in global climate in the last hundred years are significantly outside the natural range experienced in previous centuries;
- Humanity’s emissions of carbon dioxide and other ‘greenhouse gases’ (GHG) are having a dangerous impact on global climate;
- Computer-based models can meaningfully replicate the impact of all of the natural factors that may significantly influence climate;
- Sea levels are rising dangerously at a rate that has accelerated with increasing human GHG emissions, thereby threatening small islands and coastal communities;
- The incidence of malaria is increasing due to recent climate changes;
- Human society and natural ecosystems cannot adapt to foreseeable climate change as they have done in the past;
- Worldwide glacier retreat, and sea ice melting in Polar Regions , is unusual and related to increases in human GHG emissions;
- Polar bears and other Arctic and Antarctic wildlife are unable to adapt to anticipated local climate change effects, independent of the causes of those changes;
- Hurricanes, other tropical cyclones and associated extreme weather events are increasing in severity and frequency;
- Data recorded by ground-based stations are a reliable indicator of surface temperature trends.
