Not exact matches
Gross says that the most important processes affecting day length are changes in the weather, especially unusual variations in the strength and direction of the winds, which bring on alterations in the global circulation of the atmosphere and ocean.
«If these waters no longer sink, it could have far reaching affects for global ocean circulation patterns.»
Glacial retreat affects ocean circulation patterns, fisheries and global sea level rise.
Changes in the Arctic affect the rest of the world, not only in obvious ways (such as the Arctic's contribution to sea - level rise), but through the Arctic's role in the global climate system, its influence on ocean circulation, and its impacts on mid-latitude weather.
Scientists also think that the circulation of heat from the top layers of the ocean, which have been most affected to date, to the deeper oceans below may be another factor behind the «hiatus» in global warming.
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.»»
That is because there are factors, like air and ocean circulation patterns, that affect both the rate and the intensity of the global warming.
Opening of the Drake Passage surely affected ocean circulation around Antarctica, but efforts to find a significant effect on global temperature have relied on speculation about possible effects on atmospheric CO2 [37].
Sea ice can strongly affect global systems, influencing ocean circulation patterns, levels of reflected radiation (10, 11), and rates of climate change (12).
