Sentences with phrase «global ocean currents»

This movement of air affects global ocean currents and precipitation patterns.

Greenland's ice sheet melts and sends large amounts of fresh water into the coastal waters, where it is of major importance for local production but potentially also for global ocean currents.

This small warming is likely a result of the natural alterations in global ocean currents which are driven by ocean salinity variations.

Gray believes that the increased atmospheric heat — which he calls a «small warming» — is ``... likely a result of the natural alterations in global ocean currents which are driven by ocean salinity variations.»

During the last ice age, when thick ice covered the Arctic, many scientists assumed that the deep currents below that feed the North Atlantic Ocean and help drive global ocean currents slowed or even stopped.

But in a new study in Nature, researchers show that the deep Arctic Ocean has been churning briskly for the last 35,000 years, through the chill of the last ice age and warmth of modern times, suggesting that at least one arm of the system of global ocean currents that move heat around the planet has behaved similarly under vastly different climates.

Warming temperatures in the Arctic may cause large amounts of fresh meltwater to enter the north Atlantic, possibly disrupting global ocean current patterns.

Figure 1 shows general global ocean currents.

Investigators plan to anchor three arrays in the polar regions, where climate change could dramatically impact ice formation and global ocean currents.

The observed increase in freshwater content will affect the conditions in all Greenland fjords and may ultimately affect the global ocean currents that keep Europe warm.

The major «pumps» for the global ocean currents are at high latitudes, and there is good reason to believe that those pumps will be affected by climate - related changes in the atmosphere.

Peter Ward on the consequences of this development: «When [the global ocean current conveyor belt] stops, we lose oxygen at the bottom, and we start the process toward mass extinction.»
