So was there a climate shift after the turn of the century involving changes in ocean and atmospheric circulation involving cloud changes?

Because melting is so much more energetically efficient than sublimation, the main way that moderate changes in atmospheric conditions — including air temperature — affect ablation is through changing the number of hours during which melting occurs, and the amount of energy available for melting.

It is also my understanding that the oceanic and atmospheric circulations are intrinsically linked, so that changes in one are likely to lead to changes in another.

And given the fact that land warms more quickly than ocean, resulting in areas of low pressure over land, changing patterns of atmospheric and oceanic circulation are bringing them to the coasts — where so much life's diversity is found.

[Response: Changes in the atmospheric composition are negligible for their effect on the gas law, but not in terms of radiative transfer, so your conclusion is invalid.]

So, we don't have time to sit and slowly change things, and the only way to reduce consumption and atmospheric carbon in ways that do it fast enough to limit SLR to 10 ft. or so, avoid destruction of global potable water resources, and create equity and justice within a new, sustainable paradigm is rapid simplificatioSo, we don't have time to sit and slowly change things, and the only way to reduce consumption and atmospheric carbon in ways that do it fast enough to limit SLR to 10 ft. or so, avoid destruction of global potable water resources, and create equity and justice within a new, sustainable paradigm is rapid simplificatioso, avoid destruction of global potable water resources, and create equity and justice within a new, sustainable paradigm is rapid simplification.

In their latest Science paper submittal Jim Hansen, et al. argue that we must reduce atmospheric CO2 to below 350 ppm because so - called «slow feedbacks» such as changes in ice sheet albedo are occurring much faster than expected.

This assumes that the main atmospheric circulation patterns don't change much (or is second order, as seems to be the case) and so the moisture that is evaporated into atmosphere and is lying around gets transported to where it already rains and away from the areas where it doesn't.»

So, we might have been past the warmest period of this most recent interglacial, and beginning a slow, multi-thousand year descent into a new ice age — until we changed the atmospheric composition.

The argument is then that the reason trends outside the Atlantic are weak is that they aren't being influenced by the AMO; the other explanation is that the other regions are already over the threshold, so that the Atlantic basin is more sensitive to changes in SSTs and atmospheric moisture than the other regions... or the data may be poor.

a) atmospheric CO2 from human activity is a major bause of observed warming in the 1980's and 1990's, c) that warming is overstated due to a number of factors including solar effects and measurement skew d) the data going back 150 years is of little reliability because it is clustered so heavily in northeast america and western europe rather than being global e) the global climate has been significantly shifting over the last thousand years, over the last ten thousand years, and over the last hundred thousand years; atmospheric CO2 levels did not drive those changes, and some of them were rapid.

[Response: A small new source is swamped by larger already existing sources, so the relative change in the atmospheric concentration is relatively small.

If so, I think we want to include tightly coupled chemical and biological processes, in that case — for example, the chemical fate of atmospheric methane over time, the effects of increasing atmospheric CO2 on oceanic acid - base chemistry, and the response of the biological components of the carbon cycle to increased temperatures and a changing hydrologic cycle.

So if there were, say, a decadal - scale 1 % -2 % reduction in cloud cover that allowed more SW radiation to penetrate into the ocean (as has been observed since the 1980s), do you think this would have an impact of greater magnitude on the heat in the oceans than a change of, say, +10 ppm (0.00001) in the atmospheric CO2 concentration?

This necessitates taking into account atmospheric radiative transfer so that any SST warming is driven by radiative changes (e.g., changes in greenhouse gas concentrations) and resultant changes in the surface fluxes.

Everything else that might try to alter that base level simply results in atmospheric circulation changes (atmosphere includes oceans for this purpose) that adjust the rate of conversion between kinetic and potential energy so as to keep the base level of system energy content stable.

there has been no statistically discernible rise in global temperature for the most recent 15 years despite atmospheric CO2 concentration rising by ~ 4 % during that time so the rise in the CO2 is observed to not be overwhelming other causes of the temperature change, 2.

Climate models are like weather models for the atmosphere and land, except they have to additionally predict the ocean currents, sea - ice changes, include seasonal vegetation effects, possibly even predict vegetation changes, include aerosols and possibly atmospheric chemistry, so they are not like weather models after all, except for the atmospheric dynamics, land surface, and cloud / precipitation component.

But so far scientists have not been able to calculate the CO2 uptake of the sinks with sufficient accuracy to explain all the annual changes in atmospheric CO2 concentration, which hinders the scientists» ability to monitor the effectiveness of CO2 mitigations policies.

The temperature did not change, so the surface temperature - dependent responses of atmospheric radiative cooling also did not change.

However climate change is expected to keep atmospheric CO2 levels significantly elevated for about 1000 years I recall according to the IPCC, so this is effecting what, about 300 generations or so.
