By analogy, a warmer world wouldn't be rainier (or cloudier); it's an imperfect analogy, because rain isn't absolutely correlated with cloudiness, and lateral transport of energy by ocean, air, and latent heat currents in and out of the E & W Pacific Ocean areas won't scale to global waocean, air, and latent heat currents in and out of the E & W Pacific Ocean areas won't scale to global waOcean areas won't scale to global warming

They relate the current hiatus period at the surface and a deeper penetration of the warming into the ocean with changes in the trade winds on the subtropical Pacific (intensification).

We work with global ocean circulation models to understand issues like the thermal expansion of ocean waters due to global warming or the effect of changing ocean currents on regional sea levels.

There is some discussion over what effect greenhouse warming will have on ocean currents, particularly the Gulf Stream, which warms Europe with tropical water.

They also found that, consistent with my team's research, about 30 % of overall global warming has gone into the deep oceans below 700 meters due to changing wind patterns and ocean currents.

Part of problem is that even with current levels of emissions, the inertia of the climate system means that not all of the warming those emissions will cause has happened yet — a certain amount is «in the pipeline» and will only rear its head in the future, because the ocean absorbs some of the heat, delaying the inherent atmospheric warming for decades to centuries.

Previous large natural oscillations are important to examine: however, 1) our data isn't as good with regards to external forcings or to historical temperatures, making attribution more difficult, 2) to the extent that we have solar and volcanic data, and paleoclimate temperature records, they are indeed fairly consistent with each other within their respective uncertainties, and 3) most mechanisms of internal variability would have different fingerprints: eg, shifting of warmth from the oceans to the atmosphere (but we see warming in both), or simultaneous warming of the troposphere and stratosphere, or shifts in global temperature associated with major ocean current shifts which for the most part haven't been seen.

The Gulf Stream, together with its northern extension, North Atlantic Current, is a powerful, warm, and swift Atlantic Ocean current that originates in the Gulf of Mexico, exits through the Strait of Florida, and follows the eastern coastlines of the United States and Newfoundland to the northeast before crossing the AtlanticCurrent, is a powerful, warm, and swift Atlantic Ocean current that originates in the Gulf of Mexico, exits through the Strait of Florida, and follows the eastern coastlines of the United States and Newfoundland to the northeast before crossing the Atlanticcurrent that originates in the Gulf of Mexico, exits through the Strait of Florida, and follows the eastern coastlines of the United States and Newfoundland to the northeast before crossing the Atlantic Ocean.

A greater - than - normal volume of warm salty tropical water was transported north with the current and this was drawn down into the ocean in the region around 60 ° N - where dense water sinking occurs.

For example, because the mass balance argument says nothing about absolute numbers or attribution it may be that we are also — for example — destroying carbon - fixing plankton, reducing the breaking of waves and hence mechanical mixing with the upper ocean, releasing methane in the tundra which was previously held by acid rain and which can now be converted to CO2, or it may be we are just seeing a deep current, a tiny bit warmer than usual because of the MWP, heating deep ocean clathrate so that methanophage bacteria can devour it and give off CO2.

This empirical finding contradicts Spencer's hypothesis that cloud cover changes are driving global warming, but is consistent with our current understanding of the climate: ocean heat is exchanged with the atmosphere, which causes surface warming, which alters atmospheric circulation, which alters cloud cover, which impacts surface temperature.

Methane Hydrates» Melt - was first observed to be accelerating during the last decade, with sufficient ocean warming reaching the hydrates in the sea bed of continental shelves off Norway and eastern Canada, where the hydrate stocks are vulnerable to newly warmed currents.

It's very clear (thanks to Steve M, Willis etc) that there are issues with both but given the current hyped claim by the «warmers» that the past effects of man - caused global warming have largely been masked by the warming of the oceans and that unless we reduce CO2 emissions now that we won't be able to mitigate future global warming when this «stored heat» eventually comes back out of the oceans and leads to catastrophic effects, I'm very interested in getting to the punchline of this debate on SSTs.

The subsiding air warms by compression and, coupled with cooling of the lowest layers overlying the cold ocean currents normally found off the west coasts of the continents, forms a pronounced temperature inversion (warm air over cold), called the trade - wind inversion.

But if you accept that the greenhouse effect is real, and that CO2 is a GHG, and that CO2 has increased (along with other GHGs), you have to accept the merit of my point: that solar, volcanoes, ocean currents and other natural variations do their thing, they vary, but GHGs exert a steady, constant upward forcing on temperature, which upward forcing is only offset by increased heat losses to space from a warmer planet.

In any case, all his point about the fact that the Arctic has been showing some signs of warming was disposed of very thoroughly by NASA last year in a paper saying that most of that warming is attributable to changes in the great ocean currents as they push more warmer water up to the Arctic and this has nothing to do with global warming.

Also, couldn't changes in ocean currents have caused warming in various locations that would not be inconsistent with a causal link between CO2 and warming?

With the help of precise satellite data and an extensive suite of climate model simulations the current research was able to observe that the upper - ocean warming was underestimated by up to 58 percent.

By an intelligent diversion of warm ocean - currents together with some means of colouring snow so that the sun could melt it, it might be possible to keep the Arctic ice - free for one summer, and that one year might tip the balance and permanently change the climate of the northern hemisphere.

I like the 50 - 50 treatment but I think the surface warming to date, 1 degree, combined with continued rollover mixing of the oceans, thermohaline currents and tropical counter currents, etc., will lose all the future trapped heat in the deep ocean.

The effects of this marked shift in westerly winds are already being seen today, triggering warm and salty water to be drawn up from the deep ocean, melting large sections of the Antarctic ice sheet with unknown consequences for future sea level rise while the ability of the Antarctic Circumpolar Current to soak up heat and carbon from the atmosphere remains deeply uncertain.

And that, combined with the current record ocean temperatures — and faster than expected warming of the ocean's surface layer — means we can expect a continuation of the unexpectedly fast loss of Arctic sea ice and of land - locked ice in Greenland and Antarctica.

The current warming trend can not be due to «natural variability» because at present both ocean temperatures and land temperatures are warming which requires an external forcing and land temperatures are warming faster than ocean temperatures which can not occur with internal variability of the ocean - atmospheric system.

Instead D'Aleo contends that the global warming trend correlates more closely with other phenomena such as solar activity and ocean current oscillations.

The researchers, most of them based at Columbia University's Lamont - Doherty Earth Observatory, say it cements the theory that atmospheric moisture, and thus dust, move in close step with temperature on a global scale; the finding may in turn help inform current ideas to seed oceans with iron - rich dust in order to mitigate global warming.
