1. Climate always changes, gradually, catastrophically, and unpredictably. It would be especially newsworthy if climate stopped changing;

2. Climate change is governed by millions of factors (variables), from the swish of a butterfly's wing, through volcanic eruptions, landscape alterations, natural fluctuations in greenhouse gases, changes in oceanic currents and salinity, variations in the Earth's orbit and axis, sunspot cycles, to dust and meteors;

3. Much of the debate is based on associations (correlations) between extremely short-run data sets, often collected and averaged in unhelpful ways. Correlations tell us nothing about processes;

4. Carbon dioxide is often taken as a proxy for all the other greenhouse gases. This is not acceptable, especially as the models are largely unable to cope with the most important greenhouse gas of all, water vapor;

5. Our climate models come nowhere near to being able to predict climate change. The current direction of change remains unproven, with balloon and corrected satellite measurements, along with some high-latitude ground measurements, still indicating cooling, not warming. It is also possible that any warming signature is really reflecting only the processes of global urbanization.
