The fall of the temperature of the sea water is sometimes a sign of the proximity of ice, although in regions where there is an intermixture of cold and warm currents going on, as at the junction of the Labrador Current and the Gulf Stream, the temperature of the sea has been known to rise as the ice is approached.

If you decouple that ice from where it's grounded — something that currents of warming water, already circulating around the Antarctic coast, could do — then water could flow beneath the inland ice and lubricate its slide into the ocean.

As astronomical cycles they are predictable into the future and will cause another ice age probably in around 50,000 years (that depends on where the threshold for glaciation is, and what future CO2 levels will be at that time), but there is no way the Milankovich cycles could explain the current global warming.

Other factors would include: — albedo shifts (both from ice > water, and from increased biological activity, and from edge melt revealing more land, and from more old dust coming to the surface...); — direct effect of CO2 on ice (the former weakens the latter); — increasing, and increasingly warm, rain fall on ice; — «stuck» weather systems bringing more and more warm tropical air ever further toward the poles; — melting of sea ice shelf increasing mobility of glaciers; — sea water getting under parts of the ice sheets where the base is below sea level; — melt water lubricating the ice sheet base; — changes in ocean currents -LRB-?)

As Milankovic warming in the norther hemisphere is carried into the shallow return current, the Antarctic Ice margin retreats; a tipping point is reached where the Drake Passage flow restarts or increases above a threshold.

To make things even more difficult, the current rate of warming is not comparable with previous periods, where greenhouse gas increases were much slower.

While it has gotten about one degree warmer since 1900, there is no clear evidence that current climate is anywhere outside of natural variability, and mankind is, at this time, successfully living in climate extremes ranging from the far North to the Equator where climate differences are much more than 3C.

But from a somewhat larger perspective, this scientific result is just one piece of a host of results all indicating where the current warming comes from.

And in some articles where I have read that it is being observed, often historical data shows those cities and / or regions to have been warmer in the past century, which would seem to indicate (1) the permafrost issue isn't new or necessarily unnatural and / or (2) there is a substantial lag between permafrost melting and rising temps (ie, the current permafrost melt is mostly or all natural).

These are large rotating masses of water, in each ocean basin, where ocean currents converge at their centre and are forced downwards, taking warm surface water with them.

In geological time, the balance of the system has changed several times, and just like any system can have a resonance at certain points, the climate can reach a resonant point where it is teetering between two states (our current 100,000 year ice age warm period cycle).

But as cogently interpreted by the physicist and climate expert Dr. Joseph Romm of the liberal Center for American Progress, «Latif has NOT predicted a cooling trend — or a «decades - long deep freeze» — but rather a short - time span where human - caused warming might be partly offset by ocean cycles, staying at current record levels, but then followed by «accelerated» warming where you catch up to the long - term human - caused trend.

Where do you believe that Dr. Curry implies agreement that leading climate scientists are incompetent and should not be working, and that there is a cover - up and that the current warming is caused by an iron sun rather than increased CO2 from human activity?

Some of the warm water would be subducted by Atlantic Meridional Overturning Circulation / Thermohaline Circulation, some would be carried by ocean currents into the Arctic Ocean where it would melt sea ice, and the remainder would be spun southward by the North Atlantic gyre toward the tropics so it could be warmed more by the effects of the slower - than - normal trade winds.
