Dr. Stephen Schneider - In the 70's he was chanting about global cooling due to dust concentration in the atmosphere. He's now joined the global warming bandwagon.
There are others in this too but we have had Newsweek, Time, and Fortune champion this global cooling notion in the past.
Who do we believe? Is their "evidence" and/or reasoning any better today than it was just a few years ago?

Look, its the typical parade of conservative talking points to use to deny that the climate is changing due to anthropogenic sources.
The science of climate has advanced since the 1970's (with computers, satellites and such), hence the analysis and prediction of climate are much more accurate and sophisticated than 30 years ago.
Gee, doctors in the 50's were saying it was good to smoke!! Now they say the opposite!! Who to believe?!?!?!
And Reid Bryson was the most important figure in climatology. He essentially you to listen invented the science after WWII. And if you ask him today, today's scientists are correct - our science is better today than 30 years ago (what find of fool would argue otherwise...oh wait)
Later you say:
And? Can you show these "additive" effects? Quantify them? Even conclusively identify them?
What say you about the global cooling bleaters? Seems that used to be the environut chant of yesteryear...
CsG
Yes!! These additive effects are quantified and identified. We know that an x-increase in CO2 concentration in the atmosphere will result in an y-increase of radiation on the earth's surface. And yes there are numbers for x and y, and these numbers are scientifically proven.
What about the smoking is good for you bleaters?? Seems that used to be the medicalnut chant of yesteryear....I'm not going to listen to a word those doctors have to say.
earlier you say:
"Scientists" have argued that the earth was cooling - are we causing some "additional" effects in those cases too? You see -the whole issue is absurd because there is nothing showing causation by humans - let alone something quantitative(either way).
This shows how little you know about this subject. The science that said the earth was cooling is lightyears behind current science. We know man releases a bunch of CO2 and other gases into the atm. and we know what the resultant increase in radiation is from those gases. How do you not follow this logic??
No "bogus claims" - these people exist and so do the wailings published about global cooling.
Lets see one of these global cooling papers less than 30 years old. Where are they?? You act as though they were talking about global cooling 5-10 years ago.

I have the well-documented evidence that the scientists at the weather service usually can't predict what the weather will be like tomorrow with anything remotely resembling accuracy. The same computer models being used to predict the weather forecast are used to predict global warming.
How embarassing. How do you expect to have any kind of credibility on a subject when you say things like this?? Page 1 of any book on climate will explain that weather and climate are two different things. Computer weather and climate models are very different things predicting different variables.
Vic furthur embarasses himself when he says:
The ozone layer is a perfect example. For all scientists know, holes appear and disappear on a regular basis. So, yes, just like with global warming, it was politics that caused them to believe that corelation equals causation despite a complete absence of evidence.
We know what causes the ozone hole, what destoys it, how it forms. This is basic atmospheric chemistry. This is a great example of how political action has helped the environment. The destruction of ozone has been slowed by bans on CFCs.
This is all typical right wing rhetoric on this subject - deny, obfuscate, point to the same group of oil industy supported skeptics, and remain willfully ignorant of the facts and science surrounding the issue.
