Because the drains out of the various bathtubs involved in the climate — atmospheric concentrations, the heat balance of the surface and oceans, ice sheet accumulations, and thermal expansion of the oceans — are small and slow, the emissions we generate in the next few decades will lead to changes that, on any time scale we can contemplate, are irreversible.

Terrell Johnson, reporting on a recent NASA publication concluding that deep ocean temperatures have not increased since 2005 (http://www.weather.com/science/environment/news/deep-ocean-hasnt-warmed-nasa-20141007): «While the report's authors say the findings do not question the overall science of climate change, it is the latest in a series of findings that show global warming to have slowed considerably during the 21st century, despite continued rapid growth in human - produced greenhouse gas emissions during the same time.»

I also used my implementation to break up a quick land response from a slow ocean response to see if the change in sign of the derived temperature derivative coming at a place where it is not intersecting the instantaneous temperature might be explained by the derived temperature being an average.

Based on evidence from Earth's history, we suggest here that the relevant form of climate sensitivity in the Anthropocene (e.g. from which to base future greenhouse gas (GHG) stabilization targets) is the Earth system sensitivity including fast feedbacks from changes in water vapour, natural aerosols, clouds and sea ice, slower surface albedo feedbacks from changes in continental ice sheets and vegetation, and climate — GHG feedbacks from changes in natural (land and ocean) carbon sinks.

My opinion expressed elsewhere is that almost all the temperature changes we observe over periods of less than a century are caused by cyclical changes in the rate of energy emission from the oceans with the solar effect only providing a slow background trend of warming or cooling for several centuries at a time.

The slowed surface warming is due in large part to changes in ocean cycles, particularly in the Pacific Ocean, causing more efficient ocean heat uptake, thus leaving less heat to warm surface temperatocean cycles, particularly in the Pacific Ocean, causing more efficient ocean heat uptake, thus leaving less heat to warm surface temperatOcean, causing more efficient ocean heat uptake, thus leaving less heat to warm surface temperatocean heat uptake, thus leaving less heat to warm surface temperatures.

What I am not clear on is what has changed in the last few years to cause more heat to be captured by the oceans and less in the atmosphere with the resultant slower rate of surface or atmospheric warming.

With the recent decline in solar flux and the shift to cool phases of ocean oscillations, natural climate change suggests that although glacier retreat and sea level rise will likely continue over the next few decades, the rates of sea level rise and glacier retreats will slow down.The next decade will provide the natural experiment to test the validity of competing hypotheses.

While the warming of global surface temperatures has slowed somewhat, that appears to primarily be due to changing ocean cycles, particularly in the Pacific.

In light of such uncertainty, Eyre said, the best course of action is to continue working to slow ocean acidification, and climate change generally, before its effects grow too much worse.

To point out just a couple of things: — oceans warming slower (or cooling slower) than lands on long - time trends is absolutely normal, because water is more difficult both to warm or to cool (I mean, we require both a bigger heat flow and more time); at the contrary, I see as a non-sense theory (made by some serrist, but don't know who) that oceans are storing up heat, and that suddenly they will release such heat as a positive feedback: or the water warms than no heat can be considered ad «stored» (we have no phase change inside oceans, so no latent heat) or oceans begin to release heat but in the same time they have to cool (because they are losing heat); so, I don't feel strange that in last years land temperatures for some series (NCDC and GISS) can be heating up while oceans are slightly cooling, but I feel strange that they are heating up so much to reverse global trend from slightly negative / stable to slightly positive; but, in the end, all this is not an evidence that lands» warming is led by UHI (but, this effect, I would not exclude it from having a small part in temperature trends for some regional area, but just small); both because, as writtend, it is normal to have waters warming slower than lands, and because lands» temperatures are often measured in a not so precise way (despite they continue to give us a global uncertainity in TT values which is barely the instrumental's one)-- but, to point out, HadCRU and MSU of last years (I mean always 2002 - 2006) follow much better waters» temperatures trend; — metropolis and larger cities temperature trends actually show an increase in UHI effect, but I think the sites are few, and the covered area is very small worldwide, so the global effect is very poor (but it still can be sensible for regional effects); but I would not run out a small warming trend for airport measurements due mainly to three things: increasing jet planes traffic, enlarging airports (then more buildings and more asphalt — if you follow motor sports, or simply live in a town / city, you will know how easy they get very warmer than air during day, and how much it can slow night - time cooling) and overall having airports nearer to cities (if not becoming an area inside the city after some decade of hurban growth, e.g. Milan - Linate); — I found no point about UHI in towns and villages; you will tell me they are not large cities; but, in comparison with 20-40-60 years ago when they were «countryside», many small towns and villages have become part of larger hurban areas (at least in Europe and Asia) so examining just larger cities would not be enough in my opinion to get a full view of UHI effect (still remembering that it has a small global effect: we can say many matters are due to UHI instead of GW, maybe even that a small part of measured GW is due to UHI, and that GW measurements are not so precise to make us able to make good analisyses and predictions, but not that GW is due to UHI).

How such a warming would impact the probability of irreversible changes to elements of the climate system (melting ice sheets, reversal or slowing of ocean currents, release of carbon in permafrost) is unknown.

You don't think perhaps that celestial cycles just might have an effect on magma currents (yes just like the ocean, just slower) and that effect translates to changes in sea - floor seismic activity from time to time?

Slow variations in upper ocean heat content that have been observed in the subpolar and marginal ice zone regions of the Atlantic since the mid-twentieth century are thought to be related to changes in the strength of the Atlantic Meridional Overturning Circulation (AMOC).

For example, a recent slowing in the rate of surface air temperature rise appears to be related to cyclic changes in the oceans and in the sun's energy output, as well as a series of small volcanic eruptions and other factors.

Indeed, the long lifetime of fossil fuel carbon in the climate system and persistence of the ocean warming ensure that «slow» feedbacks, such as ice sheet disintegration, changes of the global vegetation distribution, melting of permafrost, and possible release of methane from methane hydrates on continental shelves, would also have time to come into play.

The fast uptake to oceans is likely to slow down gradually due to changes in ocean chemistry, but the slower processes will gradually have more and more importance.

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.

The net carbon in the atmosphere is about 2.5 % of the carbon in solution in the ocean so the change in the ocean will be slow (CO2 can only diffuse from the atmosphere into the ocean at the surface).

Climate change commitment - Due to the thermal inertia of the ocean and slow processes in the biosphere, the cryosphere and land surfaces, the climate would continue to change even if the atmospheric composition were held fixed at today's values.

The remaining slow drift to lower GMT and pCO2 over glacial time, punctuated by higher - frequency variability and the dust − climate feedbacks, may reflect the consequences of the growth of continental ice sheets via albedo increases (also from vegetation changes) and increased CO2 dissolution in the ocean from cooling.

-- Other processes are very slow in change: vegetation area increase / decrease, ocean overturning rate, rock weathering,..

What's happening in Berlin, Alaska is what climate scientists describe as slow - onset climate change event, such as sea level rise or ocean acidification.

One question posed by climate change is «will melting land ice and sea ice in the Arctic slow down or even shut down a vital part of the ocean circulation in the North Atlantic?»

The essential condition may be orbital cycles and slow changes in insolation in high latitudes — but the glacial trigger is likely to be warmth itself freshening and warming the Arctic ocean.

I believe the IPCC plans all call for a black box solution where we develop a technology to remove carbon dioxide from the atmosphere or ocean to drive the CO2 levels or to at least slow the rise of CO2 and give us more time to make fundamental changes in the way we live to limit global warming to some arbitrary level.

Just for one example, if it turns out that, between melt of sea ice and Greenland ice, the North Atlantic Current slows or stops, we would expect to see fairly dramatically colder weather in Europe for a while, even thought this condition could be directly linked to results produced by GW (though in the long term, the warming would, presumably eventually overtake the cooling from change in ocean currents).
