Sentences with phrase «alter ocean circulation patterns»

The loss of Arctic Sea ice could alter ocean circulation patterns and trigger changes in global climate patterns.

Not exact matches

There is so little understanding about how the ocean parses its response to forcings by 1) suppressing (local convective scale) deep water formation where excessive warming patterns are changed, 2) enhancing (local convective scale) deep water formation where the changed excessive warming patterns are co-located with increased evaporation and increased salinity, and 3) shifting favored deep water formation locations as a result of a) shifted patterns of enhanced warming, b) shifted patterns of enhanced salinity and c) shifted patterns of circulation which transport these enhanced ocean features to critically altered destinations.

Francis, who wasn't involved with either study, is one of the main proponents of an idea that by altering how much heat the ocean lets out, sea ice melt and Arctic warming can also change atmospheric circulation patterns, in particular by making the jet stream form larger peaks, or highs, and troughs, or lows.

If human - caused warming continues to alter these complex circulation patterns, the study's models predict more rain in the eastern tropical regions of the Indian Ocean and drought in the western equatorial Indian Ocean region.

Scientists have recently observed major changes in these glaciers: several have broken up at the ocean end (the terminus), and many have doubled the speed at which they are retreating.2, 5 This has meant a major increase in the amount of ice and water they discharge into the ocean, contributing to sea - level rise, which threatens low - lying populations.2, 3,5 Accelerated melting also adds freshwater to the oceans, altering ecosystems and changing ocean circulation and regional weather patterns.7 (See Greenland ice sheet hotspot for more information.)

Accelerated melting also adds more freshwater to the oceans, altering ecosystems and changing ocean circulation and regional weather patterns.9

Periodic events called El Niño and La Niña alter the circulation of warmer and cooler water in ocean currents, leading to changes in climatic patterns across large regions.

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.

Falling back on the surface temperatures as the metric for the most societal relevant climate metric, even if its period of record is longer, is not a reason to focus on it, if it does not serve the purpose of telling us if humans are significantly altering these circulation patterns, and thus the weather and ocean conditions that matter the most in terms of the impacts on water resources, food, energy, human health and ecosystem function.

Such a change could alter both ocean and atmospheric circulation patterns around the world.

21 March, 2018 — Runaway climate change will alter the pattern of ocean productivity and circulation and play perhaps irreversible havoc with fish catches.

Variations in ocean circulation speeds account for significant instances of climate change, changing the hydrological cycle and altering atmospheric circulation patterns as well.
