Hold on here. My point was simply to point out positive feedback
mechanisms. It was claimed that there are scant few in nature. I listed
half a dozen. More than sufficient to show that there are plenty of
positive feedback mechanisms at work in climate change.
Environmental denialist Jwas was attempting to state that since no
positive feedback mechanisms exist, global warming can not be a problem.
