Comments on: The growth rate of carbon emissions has TRIPLED http://climateprogress.org/2007/05/22/the-growth-rate-of-carbon-emissions-has-tripled/ The Latest on Climate Science, Solutions, and Politics Sun, 21 Mar 2010 05:20:00 -0400 http://wordpress.org/?v=2.8.5 hourly 1 By: Jean-Pierre M http://climateprogress.org/2007/05/22/the-growth-rate-of-carbon-emissions-has-tripled/#comment-16697 Jean-Pierre M Sat, 26 Jul 2008 12:25:42 +0000 http://climateprogress.org/2007/05/22/the-growth-rate-of-carbon-emissions-has-tripled/#comment-16697 Sorry Patrick M, but your arguments do not convince me. Reminds me of Bjorn Lomborg mentioning the impact of Sun activity on earth's climate to "prove" that Climate Change is only due to Sun activity and not man-made. The phenomena and laws of physics you mention are certainly part of what is actually happening, but in staying in qualitative terms you don't mention the quantitative extent of their impact, nor seem to consider the possibility of other phenomena also playing a role. If thousands of IPCC researchers had to go through 20 years of extensive, peer reviewed, research to grasp the complexity of the many interrelated phenomena taking place in climate change science, I personnally doubt that the two phenomena you mention have enough scientific validity to back your conclusion. Cheers, Jean-Pierre Sorry Patrick M, but your arguments do not convince me.

There is no reason nor evidence to support this. As CO2 concentration increases, the gas diffusion law states that ocean CO2 capacity increases. Further, the biosphere is a more productive absorber due to "CO2 fertilization" effect. The sinks will pull more CO2 as CO2 concentrations rise. The trendlines of CO2 concentrations are not accelerating, so that even if man is outputting more CO2, the levels are not rising any faster. Thus, the carbon sinks are *not* saturating. “The carbon sinks — the oceans, forests, soils, and tundra — are saturating, even as the carbon sources — the burning of fossil fuels plus deforestation — are growing.”

If the proportion of CO2 in the atmosphere has been as infinitesimal as it apparently has for many millenia (currently totalling even with increases, less than an eighth of an inch on the total length of an atmospheric football field), and it is increasing slowly...how in God's name can you blame it for alleged climate change variations that have been with us for ever?

The quote I give about the weakening of sinks is incidental to the main point. This study, which you can access, deals with soaring human emissions of CO2, not concentrations.
