When heavy rainfall probabilities were next investigated in ensembles of two atmospheric general circulation models, run with and without anthropogenically - induced sea surface temperature changes, results were model - dependent.

In recent years, a brand of research called «climate attribution science» has sprouted from this question, examining the impact of extreme events to determine how much — often in fractional terms — is related to human - induced climate change, and how much to natural variability (whether in climate patterns such as the El Niño / La Niña - Southern Oscillation, sea - surface temperatures, changes in incoming solar radiation, or a host of other possible factors).

Please don't lose the bigger perspective and the undoubted effects of high sea surface temperatures, of which a component is human induced climate change, on these events.

Changing global temperatures induce air circulation changes as the air seeks to restore the sea surface / surface air temperature equilibrium...

Investigators outside NOAA are finding interesting trends and showing that they seem to be correlated with trends in such variables as SST [Sea Surface Temperature] in key regions, the changes of which almost certainly are due to human - induced changes in the climate, though having enough data to get all the statistics right is often problematic.

Importantly, the changes in cereal yield projected for the 2020s and 2080s are driven by GHG - induced climate change and likely do not fully capture interannual precipitation variability which can result in large yield reductions during dry periods, as the IPCC (Christensen et al., 2007) states: ``... there is less confidence in the ability of the AOGCMs (atmosphere - ocean general circulation models) to generate interannual variability in the SSTs (sea surface temperatures) of the type known to affect African rainfall, as evidenced by the fact that very few AOGCMs produce droughts comparable in magnitude to the Sahel droughts of the 1970s and 1980s.»

This basin - wide change in the Atlantic climate (both warming and cooling) induces a basin - scale sea surface temperature seesaw with the Pacific Ocean, which in turn modifies the position of the Walker circulation (the language by which the tropical basins communicate) and the strength of the Pacific trade winds.

Regional circulation patterns have significantly changed in recent years.2 For example, changes in the Arctic Oscillation can not be explained by natural variation and it has been suggested that they are broadly consistent with the expected influence of human - induced climate change.3 The signature of global warming has also been identified in recent changes in the Pacific Decadal Oscillation, a pattern of variability in sea surface temperatures in the northern Pacific Ocean.4

However, a confident assessment of human influence on hurricanes will require further studies using models and observations, with emphasis on distinguishing natural from human - induced changes in hurricane activity through their influence on factors such as historical sea surface temperatures, wind shear, and atmospheric vertical stability.

In Australia's Great Barrier Reef (GBF), the 1998 El Nino induced above average sea surface temperatures and salinity changes for 2 months triggering massive coral losses in the reef's upper 20 meters.

The observed patterns of surface warming, temperature changes through the atmosphere, increases in ocean heat content, increases in atmospheric moisture, sea level rise, and increased melting of land and sea ice also match the patterns scientists expect to see due to rising levels of CO2 and other human - induced changes (see Question 5).

Changing global temperatures induce air circulation changes as the air seeks to restore the sea surface / surface air temperature equilibrium and at the same time resolve ocean induced variations in the sun to sea / air to space equilibrium.
