Stability of the Earth's Climate System Under Anthropogenic Forcing


Large or small, instabilities are ubiquitous in the earth's climate system. A familiar example on the smaller side of the spectrum is deep convection which gives rise to convective clouds in the atmosphere. A well-known example on the larger side of the spectrum is El Niño which causes weather pattern changes across the globe. The one that we are most familiar with is perhaps the weather events or more technically synoptical scale storms. Will these instabilities assume a larger magnitude, last longer, or occur more frequently as the concentration of CO2 rises in the atmosphere? Will the earth as a whole may undergo a run-away instability to become a planet as hot as the Venus? Study of the stability of the earth's climate system under anthropogenic forcing addresses these questions.
