Sentences with phrase «warmer ocean water rather»

Not exact matches

That means that as these glaciers retreat, their fronts will remain in contact with warm ocean water that melts ice, rather than hitting higher ground anytime soon.

Europa is now thought to have an global ocean of salty water or slush rather than warm convecting ice below its icy crust (more).

Rather, warm water melting the ice at the ice / ocean interface is causing rapid changes, including ice - shelf collapse, and acceleration and recession of Pine Island Glacier.

Heat can change ocean dynamics and eventually will increase glacial melting, which is mainly responding to subsurface water rather than air warming.

So, if each underwater artic volcano emitted 1 km3 a week (a rather large average flow) and did it for a year (about 52 weeks) you would need about 620 very active and extremely powerful volcanoes in order to warm the artic ocean by just 1 C (and that ignores surface cooling, in / out water flows and time rates that would require even more volcanoes.)

While such a «missing heat» explanation for a lack of recent warming [i.e., Trenberth's argument that just can not find it yet] is theoretically possible, I find it rather unsatisfying basing an unwavering belief in eventual catastrophic global warming on a deep - ocean mechanism so weak we can't even measure it [i.e., the coldest deep ocean waters are actually warmer than they should be by thousandths of a degree]...

Also at New York Times (though what to make of «scientists said the ice sheet was not melting because of warmer air temperatures, but rather because of the relatively warm water, which is naturally occurring, from the ocean depths»...?)

Ocean oscillations and currents could (and do) cause local effects as warm and cold water interchanges, but they can not cause a global effect as they just move energy around rather than increasing it.

Of course, if the air were to be warmer than the ocean surface then evaporation would take the extra energy required from the air rather than the water and that 1 mm deep layer (0.3 C cooler than the ocean bulk) would rise to the surface and dissipate but that doesn't happen often or for long.

Only during the short periods around noon on sunny days — when the skin layer is warmer than the water below — is there any point in worrying about how long energy from DLR remains in the skin layer and what fraction is lost upward rather than downwards (warming the ocean).

Rather than this happening, the ocean may eventually warm more at the surface raising the global water vapor amounts.

Rather, it is likely that surface warming gradually stabilizes ocean stratification, thus reducing deep - water production at high latitudes, which acts to weaken advective heat uptake by meridional overturning circulation [cf. Meehl et al., 2011; 2013].»

That warming extends the 50 m or so to the seabed because we are dealing with only a polar surface water layer here (over the shelves the Arctic Ocean structure is one - layer rather than three layers) and the surface warming is mixed down by wave - induced mixing because the extensive open water permits large fetches.
