This self-description of a lukewarmer (at Bishop Hill) gave me a good laugh:
Now I’m probably some sort of a lukewarmer – I don’t e.g. agree with Turning Tide that the fact that CO2 concentrations are low means ipso facto that it is irrelevant.
Like luketoxers who acknowledge the fact that arsenic in low concentrations doesn’t ipso facto mean that it’s irrelevant. It’s like saying I’m not a total doorknob.
Curious, I went back to read what Turning Tide had written and came across this gem:
What I found most telling is how certain facts about the atmosphere are very hard to track down for the layperson. For example, I’m pretty sure the average joe has no idea how little CO2 there is in the atmosphere, and how small a proportion of that little amount is contributed by human activities. It’s almost as though there’s a conspiracy of silence to keep such information out of easily accessible sources.
Can everyone who has a CO2 concentration widget on their blog please remove it now? We’ve got to keep it a secret that its concentration is a meagre 395 parts per million.
