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.

Sea - ice biome - The biome formed by all marine organisms living within or on the floating sea ice (frozen sea water) of the polar oceaSea - ice biome - The biome formed by all marine organisms living within or on the floating sea ice (frozen sea water) of the polar oceasea ice (frozen sea water) of the polar oceasea water) of the polar oceans.

Endless stories about glaciers melting, polar bears, ice sheets in Greenland and Antarctica and sea ice form the view that there is virtually no ice left on the surface of the planet.

But deep water production by convection may be less, depending on how much NADW is Arctic in origin and how much is simply recirculated Antarctic bottom water (extremely dense water, formed as brine under the sea ice around polynas offshore of Antarctica and sliding down the continental shelf into the depths without much mixing, creates a giant pool of dense water extending all the way up the bottom of the Atlantic to about 60 ° N).

The existence of the glaciers would lower the average temperature of the Earth by reflecting back much of the sunlight that fell on them, and slowly sea ice in the Arctic Ocean would form and expand.

If you think about it and if they «are» right about both the causes and the effects (melting ice caps, raising sea levels — e.g. increased ocean surface worldwide, increased surface temperatures on land and at sea and erratic excesses in weather) then the results may well be an eventual drastic swing the other day as we see increases in reflection, evaporation and conversion of «greenhouse» gases back into inert forms!

Also, regarding subsea volacanic eruptions — a volcanic eruption involves release of magma at several thousand degrees C plus superheated gases — when that hits cold sea water you are going to have a very violent and explosive change of form from lquid water to steam combined with the release of dissolved gases (mostly CO2)-- I am not sure what laws of Chemistry and Physics you are looking at, but I would suggest that that those bubbles and heated gases and water will rise to to the surface very quickly and have a major local effect on any nearby ice.
