The models must track how carbon dioxide and other greenhouse gases cycle through the whole system — how the gases interact with plant life, oceans, the atmosphere — and how this influences overall global temperatures.

The resulting outburst of methane produced effects similar to those predicted by current models of global climate change: a sudden, extreme rise in temperatures, combined with acidification of the oceans.

The ability of the oceans to take up carbon dioxide can not keep up with the rising levels of greenhouse gases in the atmosphere, which means carbon dioxide and global temperatures will continue to increase unless humans cut their carbon dioxide emissions.

Rising global temperatures portend shifts in all these ocean currents, potentially with drastic consequences, says Albert Gabric, an environmental scientist at Griffith University in Brisbane.

«The other carbon dioxide problem», «the evil twin of global warming», or part of a «deadly trio», together with increasing temperatures and loss of oxygen: Many names have been coined to describe the problem of ocean acidification — a change in the ocean chemistry that occurs when carbon dioxide (CO2) from the atmosphere dissolves in seawater.

At that point in geological history, global surface temperatures were rising naturally with spurts of rapid regional warming in areas like the North Atlantic Ocean.

The diagnostics, which are used to compare model - simulated and observed changes, are often simple temperature indices such as the global mean surface temperature and ocean mean warming (Knutti et al., 2002, 2003) or the differential warming between the SH and NH (together with the global mean; Andronova and Schlesinger, 2001).

The CDR potential and possible environmental side effects are estimated for various COA deployment scenarios, assuming olivine as the alkalinity source in ice ‐ free coastal waters (about 8.6 % of the global ocean's surface area), with dissolution rates being a function of grain size, ambient seawater temperature, and pH. Our results indicate that for a large ‐ enough olivine deployment of small ‐ enough grain sizes (10 µm), atmospheric CO2 could be reduced by more than 800 GtC by the year 2100.

The main threats are considered to be hurricanes along with global warming and the resulting increase in ocean temperatures which cause coral bleaching.

[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?)

However, I've never seen a single media article in any U.S. press outlet that covered these issues — the large - scale evidence for global warming (melting glaciers, warming poles, shrinking sea ice, ocean temperatures) to the local scale (more intense hurricanes, more intense precipitation, more frequent droughts and heat waves) while also discussing the real causes (fossil fuels and deforestation) and the real solutions (replacement of fossil fuels with renewables, limiting deforestation, and halting the use of fossil fuels, especially coal and oil.)

As if there is no variability in global ocean CO2 uptake and variability with temperature gradients from approximately 90F to 30F.

Given that you comment that the largest differences between the different forcings is between land and ocean or between the Northern and Southern Hemispheres, have you looked at the land — ocean temperature difference or the Northern — Southern Hemisphere temperature difference, as they both scale linearly with ECS, in the same way as global mean temperature for ghg forcing, but not for aerosol forcing.

But right now no credible coupled atmosphere - ocean - ice mechanism exists that could allow you to stretch that argument to global temperatures, let alone be compatible with the myriad observables that we do have.

The warming of the world ocean is associated with an increase in global surface air temperature, downward longwave radiation, and therefore net heat flux.

The second point is that we have found distinctive variations in global warming with El Niño: a mini global warming, in the sense of a global temperature increase, occurs in the latter stages of an El Niño event, as heat comes out of the ocean and warms the atmosphere.

My amateur spreadsheet tracking and projecting the monthly NASA GISS values suggests that while 2018 and 2019 are likely to be cooler than 2017, they may also be the last years on Earth with global average land and ocean surface temperature anomaly below 1C above pre-industrial average (using 1850 - 1900 proxy).

Long waves (infrared) light from the sun, GHGs, clouds, are trapped at the surface of the oceans, directly leading to increased «skin» temperature, more water vapor (a very effective GHG), faster convection (with more loss of heat to space in the tropics),... How each of them converts to real regional / global temperature increases / decreases is another point of discussion...

The Nature study is talking about changes associated with ocean circulation even while CO2, and the global imbalance, and global temperature, is increasing.

Eight decades with a slightly negative global mean surface - temperature trend show that the ocean above 300 m takes up significantly less heat whereas the ocean below 300 m takes up significantly more, compared with non-hiatus decades.

Human water vapour emissions are irrelevant, as water vapour is in dynamic equilibrium with ocean water, an equilibrium controlled by global mean temperature, i.e., other greenhouse gases etc..

You may now understand why global temperature, i.e. ocean heat content, shows such a strong correlation with atmospheric CO2 over the last 800,000 years — as shown in the ice core records.

As I said before with exception of GISS, the other four organizations who measure global temperatures [land + ocean] show the same cooling trend from 2002.

Over very long time periods such that the carbon cycle is in equilibrium with the climate, one gets a sensitivity to global temperature of about 20 ppm CO2 / deg C, or 75 ppb CH4 / deg C. On shorter timescales, the sensitivity for CO2 must be less (since there is no time for the deep ocean to come into balance), and variations over the last 1000 years or so (which are less than 10 ppm), indicate that even if Moberg is correct, the maximum sensitivity is around 15 ppm CO2 / deg C. CH4 reacts faster, but even for short term excursions (such as the 8.2 kyr event) has a similar sensitivity.

So if you are trying to correlate something like CET or northern hemisphere trees with «global» temperatures which are predominately a function of the tropical oceans, you are likely to be disappointed since the lags are a bit complicated.

Now if someone were to day, as Judith clearly did not although she had many opportunities to do so, that «concurrent with warming of our oceans there has been a hiatus in the significantly increasing trend of global surface temperatures,» then I would have not problem with the logic.

Therefore ice sheet sensitivity to global temperature could have been quite different in the early Pliocene, compared to today's world, with stronger ocean circulation.
