Observational data on many key climatic variables is extremely limited, particularly for sluggish components of the system such as deep ocean currents.

Not exact matches

These revealed a surprising link between stratospheric winds and ocean currents as deep as 2 kilometers beneath the waves.

Thermohaline circulation, also known as the ocean's conveyor belt, refers to the deep ocean density - driven ocean basin currents.

A March study shows that one large swath of the ice sheet sits on beds as deep as 8,000 feet below sea level and is connected to warming ocean currents.

The preliminary results, analyzed by paleoclimatologist Pierre Sepulchre of the Climate and Environment Laboratory, suggest that with any channel deeper than 200 meters currents behave as though there's an entire ocean there.

As changes happen in the polar regions, they are carried around the world by ocean currents, both at the surface and in the deep ocean.

The surface heat capacity C (j = 0) was set to the equivalent of a global layer of water 50 m deep (which would be a layer ~ 70 m thick over the oceans) plus 70 % of the atmosphere, the latent heat of vaporization corresponding to a 20 % increase in water vapor per 3 K warming (linearized for current conditions), and a little land surface; expressed as W * yr per m ^ 2 * K (a convenient unit), I got about 7.093.

i.e. changes in precipitation, vegetation, deep ocean currents, etc. are at any time as likely to cool as to heat.

As the abstract to K08 talks about ocean currents and that was the impression I got from previous discussions of that paper I thought (2) was the main concern and specifically that the heat was going into the deep ocean.

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.

Instead, they see a periodic slowdown in the vast turnover of oceanic currents as locking in CO2 into the deep oceans.

The clues found in sediments deposited during the late Holocene suggest that an ocean current that circles the southern polar region, known as Circumpolar Deep Water, flowed underneath the Cosgrove Ice Shelf and melted it.

In the Atlantic Ocean, the current known as the Atlantic Meridional Overturning Circulation (AMOC) ferries warm surface waters northward — where the heat is released into the atmosphere — and carries cold water south in the deeper ocean layers, according to the National Oceanic and Atmospheric AdministraOcean, the current known as the Atlantic Meridional Overturning Circulation (AMOC) ferries warm surface waters northward — where the heat is released into the atmosphere — and carries cold water south in the deeper ocean layers, according to the National Oceanic and Atmospheric Administraocean layers, according to the National Oceanic and Atmospheric Administration.

Third, as first observed in the 1990s, the area is vulnerable to a regional ocean current, ushered in by the shape of the sea floor and the proximity of the circumpolar deep current.

«The top of the glacier is melting away as a result of decades of steadily increasing air temperatures, while its underside is compromised by currents carrying warmer ocean water, and the glacier is now breaking away into bits and pieces and retreating into deeper ground.»

However enough fresh cold water comes in on the polar currents ensure that overall the deep oceans stay as cold as (but no colder than) the poles.

This is not perfect because it is likely that climate effects such as ocean currents and oscillations, changes in biology, ice extent and volume changes, cloud cover variations, etc... are causing a kind of climactic Brownian Motion, hiding the signal in what, lacking deep understanding of these issues, we can only call noise.
