(Top left) Global annual mean radiative influences (W m — 2) of LGM climate change agents, generally feedbacks in glacial - interglacial cycles, but also specified in most Atmosphere - Ocean General Circulation Model (AOGCM) simulations for the LGM.
Scientists now estimate that the circulation of seawater through the oceanic crust accounts for 34 % of the heat input into the global oceans, about 25 % of the globe's total heat input.
In the paper Gray makes many extravagant claims about how supposed changes in the THC accounted for various 20th century climate changes («I judge our present global ocean circulation conditions to be similar to that of the period of the early 1940s when the globe had shown great warming since 1910, and there was concern as to whether this 1910 - 1940 global warming would continue.
Knowledge of dominant scales associated with mesoscale eddies enables a better understanding of the resolution requirements for the Coupled Model Intercomparison Project, the framework used for comparison of global coupled ocean - atmosphere general circulation models.
Climate scientists would say in response that changes in ocean circulation can't sustain a net change in global temperature over such a long period (ENSO for example might raise or lower global temperature on a timescale of one or two years, but over decades there would be roughly zero net change).
If somehow and I can't possibly imagine how, there was a huge increase in circulation between the surface and the deeper layers of the ocean, that would be disastrous for global temperatures but not upwards but downwards!
The increasing global temperature, for instance, is linked to the 15 percent decline in the circulation of the Atlantic Ocean, which experts fear could disrupt weather patterns.
The aim of the C - SIDE working group is to reconstruct changes in sea - ice extent in the Southern Ocean for the past 130,000 years, reconstruct how sea - ice cover responded to global cooling as the Earth entered a glacial cycle, and to better understand how sea - ice cover may have influenced nutrient cycling, ocean productivity, air - sea gas exchange, and circulation dynaOcean for the past 130,000 years, reconstruct how sea - ice cover responded to global cooling as the Earth entered a glacial cycle, and to better understand how sea - ice cover may have influenced nutrient cycling, ocean productivity, air - sea gas exchange, and circulation dynaocean productivity, air - sea gas exchange, and circulation dynamics.

In recent decades, much research on these topics has raised the questions of «tipping points» and «system flips,» where feedbacks in the system compound to rapidly cause massive reorganization of global climate over very short periods of time — a truncation or reorganization of the thermohaline circulation or of food web structures, for instance, caused by the loss of sea ice or warming ocean temperatures.
And so a strong claim can be made that climate change is now at least partially responsible for all global weather although the part played by climate change could be small for any individual climate event relative to other causes such as normal ocean circulation patterns.
The Antarctic ice sheet reached the coastline for the first time at ca. 33.6 Ma and became a driver of Antarctic circulation, which in turn affected global climate, causing increased latitudinal thermal gradients and a «spinning up» of the oceans that resulted in: (1) increased thermohaline circulation and erosional pulses of Northern Component Water and Antarctic Bottom Water; (2) increased deep - basin ventilation, which caused a decrease in oceanic residence time, a decrease in deep - ocean acidity, and a deepening of the calcite compensation depth (CCD); and (3) increased diatom diversity due to intensified upwelling.
«The authors write that North Pacific Decadal Variability (NPDV) «is a key component in predictability studies of both regional and global climate change,»... they emphasize that given the links between both the PDO and the NPGO with global climate, the accurate characterization and the degree of predictability of these two modes in coupled climate models is an important «open question in climate dynamics» that needs to be addressed... report that model - derived «temporal and spatial statistics of the North Pacific Ocean modes exhibit significant discrepancies from observations in their twentieth - century climate... conclude that «for implications on future climate change, the coupled climate models show no consensus on projected future changes in frequency of either the first or second leading pattern of North Pacific SST anomalies,» and they say that «the lack of a consensus in changes in either mode also affects confidence in projected changes in the overlying atmospheric circulation.»»
In this document, the term climate models is used for all kinds of models used for studying the global climate system, such as Earth - System Models of Intermediate Complexity (EMICs), Atmosphere - Ocean coupled Global Circulation Models (AOGCMs) and Earth System Models (ESMs)(see for the definition of some of these model categories (Meehl and Hibbard 2006; Randall et al. global climate system, such as Earth - System Models of Intermediate Complexity (EMICs), Atmosphere - Ocean coupled Global Circulation Models (AOGCMs) and Earth System Models (ESMs)(see for the definition of some of these model categories (Meehl and Hibbard 2006; Randall et al.

Furthermore, it will fuel future studies that address questions related to specific features of atmospheric - ocean circulation from subregional to global scales, and it can be built upon for use well beyond PAGES 2k.
The study, in addition to being even more terrifying than last summer's draft, may act to motivate increased urgency for scientific research in Greenland and Antarctica, especially their effects on ocean circulation — as well as increased attention to the possibility of truly dire near - term global change.
This trend is expected to continue and has implications for hydropower production, ocean circulation patterns, fisheries, and global sea level rise.

The most likely candidate for that climatic variable force that comes to mind is solar variability (because I can think of no other force that can change or reverse in a different trend often enough, and quick enough to account for the historical climatic record) and the primary and secondary effects associated with this solar variability which I feel are a significant player in glacial / inter-glacial cycles, counter climatic trends when taken into consideration with these factors which are, land / ocean arrangements, mean land elevation, mean magnetic field strength of the earth (magnetic excursions), the mean state of the climate (average global temperature), the initial state of the earth's climate (how close to interglacial - glacial threshold condition it is) the state of random terrestrial (violent volcanic eruption, or a random atmospheric circulation / oceanic pattern that feeds upon itself possibly) / extra terrestrial events (super-nova in vicinity of earth or a random impact) along with Milankovitch Cycles.
Regional circulation patterns have significantly changed in recent years.2 For example, changes in the Arctic Oscillation can not be explained by natural variation and it has been suggested that they are broadly consistent with the expected influence of human - induced climate change.3 The signature of global warming has also been identified in recent changes in the Pacific Decadal Oscillation, a pattern of variability in sea surface temperatures in the northern Pacific Ocean.4
However, it remains a major scientific challenge to model and project the changes of the magnitude and intensity of subsurface oxygen depletion because it depends on changes in ocean circulation, rates of de-nitrification, and nutrient runoff from land, and because global data coverage for chemical and biological parameters remains poor.
Although we focus on a hypothesized CR - cloud connection, we note that it is difficult to separate changes in the CR flux from accompanying variations in solar irradiance and the solar wind, for which numerous causal links to climate have also been proposed, including: the influence of UV spectral irradiance on stratospheric heating and dynamic stratosphere - troposphere links (Haigh 1996); UV irradiance and radiative damage to phytoplankton influencing the release of volatile precursor compounds which form sulphate aerosols over ocean environments (Kniveton et al. 2003); an amplification of total solar irradiance (TSI) variations by the addition of energy in cloud - free regions enhancing tropospheric circulation features (Meehl et al. 2008; Roy & Haigh 2010); numerous solar - related influences (including solar wind inputs) to the properties of the global electric circuit (GEC) and associated microphysical cloud changes (Tinsley 2008).
Such Arctic changes «could have significant ramifications for global sea level, the ocean thermohaline circulation and heat budget, ecosystems, native communities, natural resource exploration, and commercial transportation.»
Climate scientists would say in response that changes in ocean circulation can't sustain a net change in global temperature over such a long period (ENSO for example might raise or lower global temperature on a timescale of one or two years, but over decades there would be roughly zero net change).
«That water is going to go into the North Atlantic, and that happens to be the critical spot for this global conveyer belt of ocean circulation,» Shakun says.
Tide gauges have the following disadvantages for determining global sea level changes: uneven distribution around the world; missing data; spatial and temporal variations in ocean circulations; and land movements.
While on first thought this might seem undesirable because we are looking for a global number, it might make sense to separate them due to the large difference in land / ocean ratio and the fact that atmospheric circulation patterns isolate them WRT shorter term changes.

Here, we present an explanation for time - invariant land — sea warming ratio that applies if three conditions on radiative forcing are met: first, spatial variations in the climate forcing must be sufficiently small that the lower free troposphere warms evenly over land and ocean; second, the temperature response must not be large enough to change the global circulation to zeroth order; third, the temperature response must not be large enough to modify the boundary layer amplification mechanisms that contribute to making φ exceed unity.

The Atlantic meridional overturning circulation (AMOC for short) is an integral part of the global ocean conveyor belt.
1) Abstract «Such changes could have significant ramifications for global sea level, the ocean thermohaline circulation, native coastal communities, and commercial activities, as well as effects on the global surface energy and moisture budgets, atmospheric and oceanic circulations, and geosphere - biosphere feedbacks.
The magnitude of the [geomagnetic - CO2] mechanism is small compared to the magnitude of the preponderant mechanisms driving the exchange of carbon between ocean and atmosphere, such as water temperature, biological pumping, overturning circulation... it would be preposterous to make the weakening Earth's magnetic field responsible for global warming.
The medieval warm period and little ice age (whther they are local or global phenomena) are believed to be associated with thermohaline circulations in the atlantic; correct simulation of such long term internal oscillations in an ocean basin requires long term simulations for the ocean for which we don't really have any observational constraints.
In this basin, significant inter-ocean exchange of heat and salinity from the Indian and Pacific Oceans serve as the main balance for the global meridional overturning circulation (MOC).
