It's a pointless, circular argument to have to be honest. People who have decided they don't believe in it are not going to be persuaded otherwise no matter what the evidence. Same for anti-vax nuts and other fringe psuedo-/anti-science groups.
Most people (including "scientists" who aren't actually climate scientists) don't have the knowledge to evaluate the evidence either way. It's called the
Dunning-Krueger effect.
Arguments from Global Warming Skeptics and what the science really says addresses all of the so called arguments I have seen here, and many more besides. I post the link but don't expect anyone to actually read it since, of course, you already know you're right.
When I participate in debates such as this, I don't feel the need to denigrate or belittle those with a contrary view. I'd recommend the practice.
I hear the 'You aren't a Climate Scientist' argument often (except when we hear from the likes of Al Gore or Tim Flannery
) and I call it the "
shut up" effect. As in 'you aren't a climate scientist, so you don't have the knowledge to put a point of view, so just shut up'. If that line of reasoning was valid, then we couldn't have a debate about Australia becoming a republic (except for those who are constitutional lawyers). You couldn't complain about the effects of that toxic sludge from the chemical plant entering the environment, because you aren't a qualified biologist. As it happens, I have studied the earth's climate for over 30 years, as it is presented in the sedimentary rock record. It allows me to evaluate the current arguments about anthropomorphic climate change from a perspective of personal experience.
Science doesn't 'say' anything as such.
Scientific method is a tool to study and explain natural phenomena. You study a phenomena, or postulate on something, citing the evidence you have found, presenting the data and saying why the particular conclusion has been made. Its open to anyone else to challenge the conclusion and/or come up with a different one. There is usually a popular consensus at any one time, but its just that, a consensus, not "this is the final, proven, absolute fact and we can all go and lie on a beach now". Its continues as the consensus until the next best thing comes along and attracts a new consensus.
As I mentioned above, I don't mind the various theories about anthropomorphic climate change, but don't ask me to pay up because of those theories or beliefs. Those that want to are perfectly welcome to pay, as per the scheme exhibited by Qantas.
