Anyone can observe that there has been global climate change, don't need a scientist to tell me that,
Well, right here in River City (This thread) there are folks who argue there is no climate change only random changes not unlike those that have gone before or variations in weather from year to year.
Some deny that it is possible for man to alter the environment through his activities, not that he has but that he could!
Wouldn't a prudent person want to know what is going on and what if anything should be done about it and what if anything could be done about it?
Consider the argument of the beard: If I have one long hair on my chin is it a beard? How about 2? How about 3? At some point most reasonable people would agree it is a beard. Apply this reasoning to climate change and climate change caused by human activities.
Can anyone show proof that the climate never changes, not even a little bit?
Can anyone prove that human activity is incapable of changing the climate, even a little bit?
Murphy stated that whatever could go wrong usually does and at the worst possible moment. If we don't know whether or not man could have a deleterious effect on climate it would be better to err on the side of caution and check it out rather than assume everything will be OK. Is the ice on the lake strong enough to safely hold a car? Should we guess or groundlessly assume it will be OK because it was this date last year or make a couple test holes to see the thickness and be guided by the measured facts (sounds like scientific method vs baseless faith, right?)
What should reasonably be on the table for discussion is NOT idle conjecture, wishful thinking, or faith based denial but instead whether or not man could cause change and how much change is man causing, is it a problem, could it become a problem, can we do something to make it better, how to identify what if anything could/should be done. These are worthy items for serious scrutiny.
