The researchers warn, however, that the
future evolution of the AMO remains uncertain, with many factors potentially affecting how it interacts with atmospheric circulation patterns, such as Arctic sea ice loss,
changes in solar radiation, volcanic eruptions and concentrations of greenhouse gases
in the atmosphere.
Looking ahead, were
solar changes limited to what has been measured
in the last fifteen years,
future changes in the Sun's total
radiation would have only a negligible effect on the temperature increases of 1 to 3 °C that are now projected
in IPCC models for the end of the next century.
Three - dimensional (3D) planetary general circulation models (GCMs) derived from the models that we use to project 21st Century
changes in Earth's climate can now be used to address outstanding questions about how Earth became and remained habitable despite wide swings
in solar radiation, atmospheric chemistry, and other climate forcings; whether these different eras of habitability manifest themselves
in signals that might be detected from a great distance; whether and how planets such as Mars and Venus were habitable
in the past; how common habitable exoplanets might be; and how we might best answer this question with
future observations.
