To derive the climate projections for this assessment, we employed 20 general circulation models to consider two scenarios of global carbon emissions: one where atmospheric greenhouse gases are stabilized by the end of the century and the other where it grows on its current path (the stabilization [RCP4.5] and business - as - usual [RCP8.5] emission scenarios, respectively).

By examining the spatial pattern of both types of climate variation, the scientists found that the anthropogenic global warming signal was relatively spatially uniform over the tropical oceans and thus would not have a large effect on the atmospheric circulation, whereas the PDO shift in the 1990s consisted of warming in the tropical west Pacific and cooling in the subtropical and east tropical Pacific, which would enhance the existing sea surface temperature difference and thus intensify the circulation.
«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.»»
Blue - Action will through its concerted efforts therefore contribute to the improvement of climate models to represent Arctic warming realistically and address its impact on regional and global atmospheric and oceanic circulation.
And noting «zonal mean - winds constitute an important element of global atmospheric circulation,» they go on to suggest,» if the solar cycle can influence zonal mean - winds, then it may affect other features of global climate as well, including oscillations such as the NAO and MJO, of which zonal winds are an ingredient» Thus, «the cause of this forcing» as they describe it, «likely involves some combination of solar wind, galactic cosmic rays, ionosphere - Earth currents and cloud microphysics.»
The global pattern of atmospheric circulation on Mars shows many superficial similarities to that of Earth, but the root causes are very different.
In the tropics, these Atlantic / Pacific differences modulate the global Walker circulation on decadal timescales and then affect the low - frequency variability of the high - pressure ridge off the California coast through atmospheric teleconnections.
Thirdly, Earth system models have begun to incorporate more realistic and dynamic vegetation components, which quantify positive and negative biotic feedbacks by coupling a dynamic biosphere to atmospheric circulations with a focus on the global carbon cycle (Friedlingstein et al., 2003, 2006; Cox et al., 2004, 2006).
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].

While on first thought this might seem undesirable because we are looking for a global number, it might make sense to separate them due to the large difference in land / ocean ratio and the fact that atmospheric circulation patterns isolate them WRT shorter term changes.
Even seemingly small changes in global temperature have far - reaching effects on sea level, atmospheric circulation, and weather patterns around the globe.
The estimated GST drop due to fine dust from the actual atmospheric nuclear explosions based on the published simulation results by other researchers (a single column model and Atmosphere - Ocean General Circulation Model) has served to explain the stagnation in global warming.
