The slower - acting factors are the earth's orbital movements around the sun and the expansion and retreat of the polar ice caps. (usask.ca)
Other large works include «Dynamics of a Binary System: Parts A & B», a diptych of two folding patterns mapping the conflict, resolution, and orbital movements of intimate relationships. (heathergordon.transition-project.com)
The faster - acting ones are atmospheric dust; changes in ocean circulation; feedbacks due to water vapour, clouds, and snow; and the concentrations of greenhouse gases.Variations in the earth's orbital movements around the sun create very slow climate cycles. (usask.ca)
