When the markets are pricing in something like continued perfection, sometimes it doesn't take
much to jolt them
out of what is an unstable
equilibrium.
[1] CO2 absorbs IR, is the main GHG, human emissions are increasing its concentration in the atmosphere, raising temperatures globally; the second GHG, water vapor, exists in
equilibrium with water / ice, would precipitate
out if not for the CO2, so acts as a feedback; since the oceans cover so
much of the planet, water is a large positive feedback; melting snow and ice as the atmosphere warms decreases albedo, another positive feedback, biased toward the poles, which gives larger polar warming than the global average; decreasing the temperature gradient from the equator to the poles is reducing the driving forces for the jetstream; the jetstream's meanders are increasing in amplitude and slowing, just like the lower Missippi River where its driving gradient decreases; the larger slower meanders increase the amplitude and duration
of blocking highs, increasing drought and extreme temperatures — and 30,000 + Europeans and 5,000 plus Russians die, and the US corn crop, Russian wheat crop, and Aussie wildland fire protection fails — or extreme rainfall floods the US, France, Pakistan, Thailand (driving up prices for disk drives — hows that for unexpected adverse impacts from AGW?)
We've been moving CO2
out of sequestration (fossil fuels) into the more mobile atmosphere, water, biosphere — and as a result atmospheric concentrations
of CO2 will be
out of equilibrium until
much slower natural processes move the carbon
out of those compartments.
Anyway, I have encountered this question
out in the wilds, and my response was that the CO2 container would have the lower
equilibrium temperature, the N2 container the higher because the CO2 is a good LW emitter and the N2 is not, consistent with, «So if you assume that two contained «bubbles»
of gas with a given temperature were placed in space the N2 would cool
much more slowly.»
Sorry Mike, but as I pointed
out above, you're ignoring the fast -
equilibrium of Henry's law, which sets a fixed partitioning ratio
of 1:50 for how
much CO2 resides in the atmosphere and oceans respectively at the current mean surface temperature
of 15C.
I think you're conceptualizing that we have this nice stable climate system, and that as we kick it
out of equilibrium and it transitions to something else, it's not going to go quietly,
much like a river changing its course.
If a black box were the absorbing heat at maximum potential, then it theoretically emits as
much as it receives, but only if it is
out of equilibrium.
Spencer and Braswell freely admit that using their simple model is just the first step in a complicated diagnosis, but also point
out that the results from simple models provide insight that should help guide the development
of more complex models, and ultimately could help unravel some
of the mystery as to why full climate models produce high estimates
of the earth's
equilibrium climate sensitivity, while estimates based in real - world observations are
much lower.
