Changes in ocean currents are also lead to upwelling of warm water, which also increases evaporation — and thus snow.

Ocean researchers from Kiel and Finland come to this conclusion in a current study, which will be published online yesterday (September 8th) in the journal Global Change Biology.

This is an important finding because current estimates of biological activity in surface waters of the ocean rely on instruments aboard satellites that measure the color of the sea surface, which changes along with levels of chlorophyll - a, an assessment that will miss blooms of other organisms, such as bacteria.

«The winds change the ocean currents which in turn affect the climate.

There is, therefore, much current interest in how coccolithophore calcification might be affected by climate change and ocean acidification, both of which occur as atmospheric carbon dioxide increases.

The consensus is that several factors are important: atmospheric composition (the concentrations of carbon dioxide, methane); changes in the Earth's orbit around the Sun known as Milankovitch cycles (and possibly the Sun's orbit around the galaxy); the motion of tectonic plates resulting in changes in the relative location and amount of continental and oceanic crust on the Earth's surface, which could affect wind and ocean currents; variations in solar output; the orbital dynamics of the Earth - Moon system; and the impact of relatively large meteorites, and volcanism including eruptions of supervolcanoes.

If we knew ocean heat uptake as well as we know atmospheric temperature change, then we could pin down fairly well the radiative imbalance at the top of the atmosphere, which would give us a fair indication of how much warming is «in the pipeline» given current greenhouse gas concentrations.

A lot of reseach energy is being devoted to the study of Methane Clathrates — a huge source of greenhouse gases which could be released from the ocean if the thermocline (the buoyant stable layer of warm water which overlies the near - freezing deep ocean) dropped in depth considerably (due to GHG warming), or especially if the deep ocean waters were warmed by very, very extreme changes from the current climate, such that deep water temperatures no longer hovered within 4C of freezing, but warmed to something like 18C.

One needs to contrast the long - term weakening of the Walker circulation (which is robust) with the change in the models» El Nià ± o (which is not robust — there's a series of papers describing this for the current IPCC models: e.g. van Oldenborgh et al 2005 Ocean Sci., Merryfield 2005 J. Clim., Capotondi et al 2005 J. Clim., Guilyard 2005 Clim.

Many of the surface currents of the world oceans (i.e., the ocean «gyres» which appear as rotating horizontal current systems in the upper ocean) are driven by the wind, however, the sinking in the Arctic is related to the buoyancy forcing (effects that change either the temperature or salinity of the water, and hence its buoyancy).

So the researchers used monthly data from the satellite mission GRACE, or the Gravity Recovery and Climate Experiment, which measures components in the Earth's mass system such as ocean currents, earthquake - induced changes and melting ice.

Either a big chunk of ice has been melting extraordinarily fast — which would cool the surrounding air — or somehow ocean currents would have changed in a way that favoured more rapid warming of deep water.

Changes in global weather patterns As ocean heats up, hurricanes & typhoons will become more common Cause changes in ocean currents, which cause changes in wChanges in global weather patterns As ocean heats up, hurricanes & typhoons will become more common Cause changes in ocean currents, which cause changes in wchanges in ocean currents, which cause changes in wchanges in weather.

The changing phases of Atlantic hurricane activity are not completely understood; but there appears to be a link to fluctuations in the thermohaline circulation, the global pattern of ocean currents which in western Europe appears as the Gulf Stream.

It could take decades or centuries, but change will be locked in by a 3C temperature rise, which would extensively melt ice caps, shrink glaciers and thermally expand the oceans so many current coastlines and low - lying plains would be under sea level.

The Norwegians also noted very little ice around Svalbard in the early 1920's so who is to say that this recent decline isn't just part of a longer 80 - 100 year cycle, probably led by changes to ocean currents (which would explain why the Arctic has warmed, unlike the Antarctic continent).

Hi CH There are two major factor in global climatic changes (and I consider CO2 to be a minor one, taking place below the UHI)-- direct Sun - Earth link (TSI, electromagnetic, UV and particle radiation)-- Ocean heath storage (long term integration process) and distribution (ocean currents) Views of solar scientists (including Mike Lockwood) are constrained by their 1950's hero Eugene Parker's theories, which the latest discoveries often bring into quesOcean heath storage (long term integration process) and distribution (ocean currents) Views of solar scientists (including Mike Lockwood) are constrained by their 1950's hero Eugene Parker's theories, which the latest discoveries often bring into quesocean currents) Views of solar scientists (including Mike Lockwood) are constrained by their 1950's hero Eugene Parker's theories, which the latest discoveries often bring into question.

They also drive the great surface ocean currents such as the Gulf Stream: which is why ideas that these currents could stop due to changes in water temperature is absurd.

The concept is related to the more general phenomenon of climate change, which refers to changes in the totality of attributes that define climate — not only sur - face temperatures, but also precipitation patterns, winds, ocean currents, and other measures of the Earth's climate.

And global ocean currents showed signs of a melt - spurred change — which resulted in an uneven distribution of this overall rise.

Current and projected increases in Alaska's ocean temperatures and changes in ocean chemistry are expected to alter the distribution and productivity of Alaska's marine fisheries, which lead the U.S. in commercial value.

Tides are responsible for large changes in ocean surface height and in ocean currents that help set the rate at which ice melts.

These changes in location and strength of persistent pressure systems can change ocean currents which also impacts the distribution of heat from equator to pole.

A change in ocean heat content can also alter patterns of ocean circulation, which can have far - reaching effects on global climate conditions, including changes to the outcome and pattern of meteorological events such as tropical storms, and also temperatures in the northern Atlantic region, which are strongly influenced by currents that may be substantially reduced with CO2 increase in the atmosphere.

The more recent suggestion is that it is triggered by changes in polar surface pressure which modulate wind and ocean currents in both the north and south hemispheres.

At current emissions trends, average pH of the oceans would drop from about 8.1 (current levels) to at least 7.9 in about 100 years (NRC, 2011a).22 A similar change occurred over the 200,000 years leading up to the end - Permian mass extinction, which resulted in loss of an estimated ~ 90 percent or more of known species (Chen and Benton, 2012; Knoll et al., 2007).

«The winds change the ocean currents which in turn affect the climate.

In the almost sure knowledge that the earth never experienced a runaway greenhouse even with ancient CO2 levels 10 to 20 times greater than today, these anti-science scoundrels insist with a «high level of confidence» that this amplification is real and it's based on nothing more than faster than expected surface temperature rise in the past few decades which can be TOTALLY explained by multi-decadal cyclic behavior in ocean currents, trade winds, and / or solar magnetic activity causing small global average albedo changeIn the almost sure knowledge that the earth never experienced a runaway greenhouse even with ancient CO2 levels 10 to 20 times greater than today, these anti-science scoundrels insist with a «high level of confidence» that this amplification is real and it's based on nothing more than faster than expected surface temperature rise in the past few decades which can be TOTALLY explained by multi-decadal cyclic behavior in ocean currents, trade winds, and / or solar magnetic activity causing small global average albedo changein the past few decades which can be TOTALLY explained by multi-decadal cyclic behavior in ocean currents, trade winds, and / or solar magnetic activity causing small global average albedo changein ocean currents, trade winds, and / or solar magnetic activity causing small global average albedo changes.
