Sentences with phrase «between orbital variations»

Moreover, it offers a better understanding of the link between orbital variations and climate change over geologic time scales.

One approach to forecasting the natural long - term climate trend is to estimate the time constants of response necessary to explain the observed phase relationships between orbital variation and climatic change, and then to use those time constants in the exponential - response model.

Not exact matches

What this model shows is that if orbital variations in insolation impact ice sheets directly in any significant way (which evidence suggests they do Roe (2006)-RRB-, then the regression between CO2 and temperature over the glacial - interglacial cycles (which was used in Snyder (2016)-RRB- is a very biased (over) estimate of ESS.

This positive feedback is necessary to trigger the shifts between glacials and interglacials as the effect of orbital changes is too weak to cause such variation.

However, orbital forcing is by itself insufficient to explain all of this variation, and Earth system scientists are focusing their attention on the interactions and feedbacks between the myriad components of the Earth system.

The cycling of the Earth system between glacial and interglacial modes has been ultimately driven by orbital variations.
