I was thinking maybe Gore's rationale, as an advocate, was merely to use the human induced climate change theory as a means of relating to his
audience. Surely no one would do anything about it if they knew it was a natural process, not to mention they would neglect to offer any substantial
nominal contributions to such a cause as "combating global climate change". I'm sure many have come to this same conspiracy based formulation.
There is one issue I have with the latest ICCP assessment report, and that is the following statement.
“Warming tends to reduce terrestrial ecosystem and oceanic uptake of atmospheric CO2, increasing the fraction of anthropogenic emissions that
remains in the atmosphere"
Whetton, P. (2007). Intergovernmental Panel on Climate Change’s 4th Assessment Report. Retrieved January 6, 2009, from
www.csiro.au...
My problem here is that it's just a statement. The basic reasoning is: if there is less release of CO2 by terrestrial and oceanic systems, then there
is less CO2 in the atmosphere coming from natural sources, and therefore what logically remains is human produced CO2. Honestly, that was the best
conclusion that report gave. It didn't even bother to examine whether or not the actual physical amount of human produced CO2 was substantial enough
to have any effect on global warming or regional climate change. They basically assumed that because global warming was happening and that because
there is a larger proportion of human produced CO2 in the atmosphere in contrast from natural sources, then this warming must have been induced by
human activity and industry. Still, the scientific community has failed to address any quantitative analysis on the volume of human produced carbon
emissions, which might have a substantial impact on the the planet's climate.
The final portion of report, which is the really the only relevant one, is rife with uncertainty, as any conclusion on human induced climate change is
met with obviously biased conjecture. What it does prove is that global warming is in fact occurring, but it goes confidently further in its
redundancy to affirm the fact that the largest proportion of CO2 in the atmosphere comes from human sources. So what? We all know that. Is it actually
causing the problem? They present two weak correlative data, that 1) human CO2 remains in the atmosphere even after emissions from natural sources is
reduced, and 2) global warming is in fact occurring (duh!?). With those two points they go on to assume that naturally, they must corroborate each
other, yet the report doesn't even bother addressing any such conclusion! Are they that arrogant to believe their opinion is fact? What's written in
those reports is important. Some governments base most of their climate change objectives on the opinions of these institutions. What situation will
we be in when they're no longer reliable? Or when their information is being treated as valid when it certainly is not comprehensive enough.
Anyway, while I might not be qualified to make any objection to the above statement or even issues provided, I find it highly inconclusive and
incomplete. No scientist from any other field could possibly expect such academic lenience as this report has been given (probably because the
governments are funding their Universities; critical attacks on such reports might be minimized by department heads with reputations at stake).
Just an aside now. I was always under the impression that warm temperatures encouraged the proliferation of life, thereby increasing the amount of CO2
intake by these systems. Surely all those biological systems are enough to reduce any impact by humans. Volcanoes have historically produced much more
CO2 and other greenhouse gas emissions than we have in our entire history. Or is the argument that the environment can't handle sustained stress?
What I think is that the specific way in which a planet warms might be used as some sort of indicator for the presence of CO2 in the atmosphere
(pretty useless if you ask me. If the presence of CO2 can't explain warming then Gore really has no foundation), but that the level of CO2 should not
necessarily suggest that CO2 is causing warming.
I'm surprised water vapor wasn't taken into consideration. There must be some complex water vapor dynamic, which affects changes in global climate.
I'm not sure if there is any research being done, but it would be interesting to hear for once. Maybe increased levels of CO2 in the atmosphere is
interfering with this theoretical environmental equilibrium inclusive of water vapor...
Footnote: Excuse me for using CO2 in place of greenhouse gasses throughout my post. While CO2 is one, it doesn't encompass all of them. It is one
common gas produced by anthropogenic means. I used it for consistency and ease of reading.
