Both of you have good points. Most scientists are not climate scientists, and there is a lot of wiggle room in the category "climate scientist". What bothers we most is when I hear such nonsense as "an overwhelming majority of scientists believe in climate change". This is a statement used by people with a particular agenda because they know the words "climate change" have been co-opted to mean "Hansen's CO2 hypothesis". But since all scientists believe in climate change, then can claim the statement is true, while not admitting how absurdly misleading it is. Or almost as ridiculous "An overwhelming majority of scientists believe in global warming"! This is probably an exaggeration. It states that most scientists believe we are in a warming period. But what does this have to do with Hansen's hypothesis??? What's important is not that most scientists think this or that, but that some scientists, who are experts in the field, don't agree. THAT should give us great pause. The only scientists that should have any standing in the debate over the validity of Hansen's CO2 hypothesis (which is what the scientific debate is really about, or should be) are those working directly in, and publishing in, this area of research. Logically this would include Ph.D. meteorologists, but not TV weatherpersons or all meteorologists certainly, and many atmospheric physicists. But, of course, the field is not strictly limited to these folks.
There are other scientists, such as myself, who have a passing interest in the CO2 hypothesis, and have read some of the original literature and studied the issue to some extent. We may be more knowledgeable than most, but our opinions don't really matter either. It is the ones working directly in the field, and publishing in that field, we should pay the most attention too.
Very well stated. We can measure "climate change." It is historical data, albeit subject to manipulation. AGW is an unproven theory of causation.
The one thing we do know for certain is that nothing obama has done, nothing we can do individually or in our communities, nothing elementary school kids are forced to do, none of it will affect future climate one whit. It is all either disguised wealth redistribution, indoctrination or empty feel goodism.
