| Disagree | Is the data fed into the IPCC computer climate models accurate? |
Determining an average of a quantity (Earth surface temperature) that is everywhere different and continuously changing with time at every point, using measurements at discrete times and places (weather stations), is virtually impossible; in that the resulting number is highly sensitive to the chosen extrapolation method(s) needed to calculate (or rather approximate) the average.

| Agree | Is there political pressure preventing objective skepticism of climate change? |
I also advance that there are strong societal, institutional, and psychological motivations for having constructed and for continuing to maintain the myth of a global warming dominant threat.

| Disagree | Will the 2007 IPCC computer models make accurate predictions? |
There is of course much more wrong with state-of-the-art global circulation models (climate models) than the assumption and implementation of CO2-H2O feedback. Although these models are among the most elaborate predictive models of complex non-linear phenomena, they are nonetheless sweeping oversimplifications of the global climate system and its mechanistic intricacies.

| Agree | Can life adapt to a warmer earth? |
As a general rule, all life on Earth does better when it’s hotter: Compare ecological diversity and biotic density (or biomass) at the poles and at the equator.

| Mostly Disagree | Does atmospheric CO2 cause significant global warming? |
CO2 increases may accompany temperature increases rather than causing them. Indeed, some high resolution studies have suggested that the temperature increases precede the CO2 increases. Interestingly, also, ice core data shows strong temporal correlations between inferred temp. and amount of dust preserved in the ice core. Finally, the older geological record shows several dramatic examples of where CO2 concentration and global average temperature were either unrelated or even anti-correlated.

| Disagree | Is global warming primarily caused by humans? |
The atmospheric greenhouse effect is a well known natural phenomenon, mostly caused by atmospheric water vapour, that keeps our planet warm and habitable whereas (anthropogenic = human-made) global warming refers to a small extra greenhouse warming (0.5-1 C/33 C; 1-5 %) allegedly arising from an increase in atmospheric concentration of the minority greenhouse effect gas CO2 (carbon dioxide) – the later increase in turn possibly arising from fossil fuel burning.
