This is post is proposed as a simple test of so-called AGW "skeptics" to see if they are entitled to their claim to skepticism. It just asks three simple questions. Any so-called AGW "skeptic" who wishes to self test their skepticism can do so by answering the questions. If all three answers are correct, you are entitled to a claim of skepticism about this aspect of climate science. You may still be unskeptical about others. Answers and follows up questions will be given in a following post if there is sufficient interest.
The questions:
In his well known book, "Heaven and Earth", Ian Plimer has claimed, "[M]assive volcanic erruptions (e.g. Mount Pinatubo) emit the equivalent of a year's human CO2 emissions in a few days." (Heaven and Earth, p. 472).
1) Is this claim true or false?
2) How do you know?
3) Explain a simple test which would establish almost certainly whether the claim is true or false, and carry it out?
Comments will be sent to moderation and published after one week to avoid cribbing.
