Here are the questions I pose to anyone on the topic:
- What percentage of warming is due to CO2 emissions due to the burning of fossil fuels?
- What percentage of warming is due to other man-caused reasons?
- What percentage of warming is due to changes in solar activity?
- What percentage of warming is due to changes in other natural reasons?
Given observed questionable surface temperature measurement stations, and a noticeable difference in surface station temperatures and atmospheric temperatures, do Climate Scientist's heavy dependence on surface temperature measurements lead to unreliable results?

Given many Climate Scientists claim solar activity plays no significant role in Climate Change, but other Climate Scientists claim the significant pause in global warming is due to a decline in solar activity, how trustworthy is the climate science regarding solar activity?

Given one can insert random numbers into Michael Mann's equation and still produce a "Hockey Stick" output, how trustworthy should Dr Mann's science be considered?

Given evidence scientist Keith Briffa selectively picked evidence to support his desired outcome, and discarded evidence which did not support his desired outcome, how trustworthy should Dr Briffa's science be considered?

Given evidence scientist Philip Jones stated he used Michael Mann's "trick" to "hide the decline" of late 20th century cooling to overstate warming in the industrial era, how trustworthy should Dr Jones's science be considered?

Given climate scientists refused to allow critical peer review of their research, and only allowed it to be peer-reviewed within their tight circle of fellow climate scientists who believed the same way they did, how trustworthy should their science be considered?

Given climate scientists working at government organizations refused FOIA requests for details of their research, how trustworthy should their science be considered?

So there it is. Why not more skepticism, not that temperatures are rising, but skepticism of the science? I have said repeatedly, Climate Science is a Social Science, not a Physical Science. It is more about computer methods and curated data, and less about measurement. And other Social Science is held to much greater skepticism than Climate Science.
