Near-Term Emissions Decisions and Long-Term Climate Impacts: Research Council Report Released
NEAR-TERM EMISSIONS CHOICES COULD LOCK IN CLIMATE CHANGES FOR CENTURIES TO MILLENNIA; REPORT ESTIMATES IMPACTS FROM VARIOUS LEVELS OF WARMINGCO2 in the atmosphere: It's *not* "long-lived"
WASHINGTON — Choices made now about carbon dioxide emissions reductions will affect climate change impacts experienced not just over the next few decades but also in coming centuries and millennia, says a new report from the National Research Council. Because CO2 in the atmosphere is long lived, it can effectively lock the Earth and future generations into a range of impacts, some of which could become very severe.

The correct evaluation of the CO2 residence time -- giving values of about 5 years for the bulk of the atmospheric CO2 molecules, as per Essenhigh's (2009) reasoning and numerous measurements with different methods -- tells us that the real world's CO2 is part of a dynamic (i.e. non-static) system, where about one fifth of the atmospheric CO2 pool is exchanged every year between different sources and sinks, due to relatively fast equilibria and temperature-dependent CO2 partitioning governed by the chemical Henry's Law (Segalstad 1992; Segalstad, 1996; Segalstad, 1998).[Iowa State: Ideal temperature for corn growth is 93 degrees F)
The crop grows according to an "S"-shaped curve depending on temperature, with the ideal temperature for crop growth, if everything else is satisfactory such as nutrition and water availability, being somewhere around 93 F (34o C)Flashback: Irreversible Warming
“We have to think about [carbon dioxide] much more like nuclear waste than, like say, smog or acid rain,” explains one of the world’s top atmospheric scientists, Susan Solomon, Senior Scientist for the National Oceanographic and Atmospheric Administration. Solomon is leading the research team. She adds, “What we’re doing with carbon dioxide is forever.”It's Inevitably Going to Get Hot Around Here, Says National Academy of Sciences - Hit & Run : Reason Magazine
Just one observation, climatologists still hotly dispute (adverb, bad as it is, intended) whether or not the planet was 2 to 4 degrees warmer on average than it is today during the Holocene Climatic Optimum, some 6,000 to 9,000 years ago.
