Sentences with phrase «increasing global circulation»

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.

Output from global circulation models indicates that climate variability will continue to be an important characteristic of the region in the future [52], but that climate change may increase the risk of extreme climatic events such as multi-decade droughts and extreme winter precipitation [53], [54].

Because radiative forcing, while it does vary somewhat with vertical profile, is relatively immune to changes of the atmosphere due to circulation, so models can do a reasonable job of predicting that the global mean temperatures increase.

The assumption of a global annual average increase in the coming decades +1 C and +2 C, is of little use in defining changes in climate impacts at the regional and local scale, which are so dependent in how large scale circulation features would change in the coming decades.

This shift is caused by global climatic warming that leads to higher energy in the general circulation: The Intertropical Convergence Zone (ITCZ)-- known more commonly as monsoon — increases in strength due to increased convection and convergence.

The Little Ice Age following the Medieval Warm Period ended due to a slight increase in solar output (changes in both thermohaline circulation and volcanic activity also contributed), but that increase has since reversed, and global temperature and solar activity are now going in opposite directions.

If this happens during northern winter, surface pressure falls in the Arctic (rising AO) the night jet stalls, NOx injection falls away, stratospheric ozone levels increase, the coupled circulation is invigorated and pressure falls at 50 - 60 ° north and this is associated with cloud loss (when global cloud cover is at its maximum value) and a strong rise in global sea surface temperature.

A slowing of this circulation is very likely over this century, but temperatures over the Atlantic and Europe are projected to increase nevertheless, due to global warming.

The circulation is accompanied somewhat by a decrease in the overall range of surface - air temperature between the equator and poles and by an overall increase in the mean global surface - air temperatures.

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 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.

The circulation shutdown would precede the rapid increase in global sea levels.

For instance, the global average temperature (as reported by NOAA, Hadley / CRU and NASA / GISS ground - based measurements, as well as RSS and UA - H satellite based measurements) has failed to increase in the 21st century the way the General Circulation Models have said they should despite the fact that CO2 has been rising unabated.

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.

Increasing galactic cosmic rays being a main factor for major volcanic activity to increase and global cloud coverage to increase while less EUV light should result in a more meridional atmospheric circulation which would also result in more clouds and also greater snow coverage.

It can also strengthen the Asian summer monsoon circulation and cause a local increase in precipitation, despite the global reduction of evaporation that compensates aerosol radiative heating at the surface (Miller et al., 2004b).

With regard to his «other hypotheses, predict the opposite» he may be referring to increased albedo due to the expectation that increased global warming increases snowfall in the northern and southern latitudes; or the shutdown of the thermohaline circulation of the ocean.

The reason why climatologists do not believe this is the whole story is because an increase in thermohaline circulation would warm only the north Atlantic, but it would cool the south Atlantic and would have hardly any effect on the Pacific or the global mean temperature.

Steadily increasing Arctic warmth could have large effects on the global thermohaline circulation (THC)(particularly in the Atlantic).
