Why is any evidence shown to cause global warming in the past, that isn't manmade, denied by the GWA's
Answer:
Global Warming is the latest and greatest cause celebre. There have been cycles of global warming and global freezing throughout earth's history. The pundits love a cause that they can overblow and use as propaganda to influence young people (and their vote).
One of my favorite authors is Michael Crichton (Jurassic Park, Andromaeda Strain, etc. ) His book, STATE OF FEAR, is one of the most well researched books on global warming I have ever read. While it is a novel, he has done an incredible amount of scientific research on the topic and has included page after page of references to actual documents that refute a lot of the scare tactics used by Al Gore and his ilk.
There are literally thousands of scientists who dispute the current frenzy but you will never see them on CNN. Those scientists can be found in every country and every major university and research center. However, because they are real scientists, not 'Shallow Hals' who want their 15 seconds on TV, you will never see or hear them or their overwhelming scientific evidence.
Crichton's book really lays out how certain large foundations and media outlets are deliberately distorting the issue to get money and to get ratings. Things that make you go h-m-m-m!
Also sad to say, a lot of Baby Boomers (like me) college professors are the leftover rose covered glasses idealists of the 60s. They do not want free discourse and exchange of ideas in the classroom, traditionally the bastion of free thought. They want only their point of view, to be free to espouse only their propaganda, and totally ignore or shut out any students who dare to question their rationale. In obtaining my masters degree in education, I was repeatedly shut down by propagandizing professors, even when I was able to provide juried evidence that disputed their rhetoric.
Instead of getting in a frenzy over the global warming 'crisis,' we all need to study our earth's history a little more, get information from a lot of different sources (not just Al Bore and CNN), and learn to think for ourselves instead of acting like a bunch of lemmings!
Who are the GWA's?
Great Question!! I live in Ohio and have always been taught that at one time, Ohio was covered by glaciers. Well, those glaciers are not here now, so the logical assumption would that at some point, LONG before man's influence, the earth, somehow warmed up to melt the glaciers. I can never get a GWA to discuss this. Us evil humans had NOTHING to do with the glaciers melting. I will look forward to reading the answer to one of the followers of the global warming religion.
It is absolutely not true that global warming advocates deny that there were periods of global warming in the past.
Read this, for example.
Your statement is dead wrong. Global warming scientists consider historical climate an important thing in their work. For example, there are pages of data and discussion about historical climate changes in the IPCC reports.
What the scientist agree about is that the data clearly shows that, about 40 years ago, Man took control of the climate from the natural forces that historically controlled it.

We simply need to give control back to nature.
Because it destroys their case. Completely. It's not just that temperatures were likely warmer during recent periods like the Medieval Warming Period, but that there was no CO2 involved, and no solar forcing involved either (the Medieval Maximum of peak solar activity did not occur until the end of the MWP after records show cooling as Earth entered the Little Ice Age.) This suggests other mechanisms at play that can cause significant climactic shifts - mechanisms that either haven't been considered or given less weight. The cumulative effect of this evidence would be to totally invalidate their computer models.
And Bob, who says, "Your statement is dead wrong", insisting that Alarmist don't deny these previous periods of global warming, earlier had this to say:
"Sorry, you're wrong. Global temperatures now are warmer than they were in the MWP. And the rate of increase is far greater than it was back then...
Show me one scientific study that says the MWP was warmer, worldwide. Not the anecdotal nonsense, just one quantitative study.
There aren't any."
Sounds like someone eager to deny global warming similar today. Even bold enough to categorically deny the existence of ANY quantitative measurements supporting a warmer MWP.

BTW, in my answer to that question, I pointed out a quantitative finding...that I found by clicking on a link within the article HE cited. Didn't take too much investigation to illustrate his baseless claim.
But that's just Bob.
Here's what the IPCC had to say:
"…current evidence does not support globally synchronous periods of anomalous cold or warmth over this time frame, and the conventional terms of 'Little Ice Age' and 'Medieval Warm Period' appear to have limited utility in describing trends in hemispheric or global mean temperature changes in past centuries".
Sounds like denial of previous global warming to me. And you don't get bigger than the IPCC. Alarmists will tell you that...it's a "consensus" thing.
