Not exact matches

That's a process playing out throughout the Southern Ocean, but scientists don't have a good grasp on it or how sudden changes like the loss of a huge hunk of ice will alter carbon uptake.

If as I suggest one includes the much denser oceans as a component of atmosphere then increases in CO2 become irredeemably trivial in terms of their power to alter overall density and thus the global heat retaining process.

On decadal and longer time scales, global mean sea level change results from two major processes, mostly related to recent climate change, that alter the volume of water in the global ocean: i) thermal expansion (Section 5.5.3), and ii) the exchange of water between oceans and other reservoirs (glaciers and ice caps, ice sheets, other land water reservoirs - including through anthropogenic change in land hydrology, and the atmosphere; Section 5.5.5).

If as I suggest one includes the much denser oceans as a component of atmosphere then increases in CO2 become irredeemably trivial in terms of their power to alter overall density and the speed of energy throughput and thus the global heat retaining process.

More broadly, variations in the attenuation of visible radiation in the upper ocean, which directly relates to changes in ZSD, alter local heating and, consequently, have an effect on the thermal and fluid dynamical processes for the ocean - atmosphere system.

It will respond to the ARCSS mandate by advancing our understanding of coupled atmosphere - ocean - ice processes with a focus on the role and response of cyclones in altering the state of the Arctic system.

From sulfur aerosols to iron ocean seeding to artificial trees to cloud whitening, new earth - altering technologies are moving from science fiction to reality, challenging the capabilities of our international institutions in the process, and forcing us to re-examine the ideas that hold our political world together.

Since to me (and many scientists, although some wanted a lot more corroborative evidence, which they've also gotten) it makes absolutely no sense to presume that the earth would just go about its merry way and keep the climate nice and relatively stable for us (though this rare actual climate scientist pseudo skeptic seems to think it would, based upon some non scientific belief — see second half of this piece), when the earth changes climate easily as it is, climate is ultimately an expression of energy, it is stabilized (right now) by the oceans and ice sheets, and increasing the number of long term thermal radiation / heat energy absorbing and re radiating molecules to levels not seen on earth in several million years would add an enormous influx of energy to the lower atmosphere earth system, which would mildly warm the air and increasingly transfer energy to the earth over time, which in turn would start to alter those stabilizing systems (and which, with increasing ocean energy retention and accelerating polar ice sheet melting at both ends of the globe, is exactly what we've been seeing) and start to reinforce the same process until a new stases would be reached well after the atmospheric levels of ghg has stabilized.

The only thing that I would contend could be added would be long slow cumulative changes in solar output other than raw TSI namely changes in the mix of particles and wavelengths over longer periods of time such as MWP to LIA to date and which seem to have some effect on surface pressure distribution and global albedo so as to alter solar shortwave into the oceans and thus affecting the energy available to the ENSO process.

When CO2 dissolves in seawater, carbonic acid forms, lowering the pH and altering the absolute and relative abundances of dissolved carbonate species; this process is known as «ocean acidification» (OA)[2].

This is the process whereby solar changes alter global cloudiness so as to change the amount of energy entering the oceans and thereby skew the balance of ENSO between El Nino warming or La Nina cooling:
