Sentences with phrase «do orbital variations»

Not exact matches

The theory of direct orbital forcing is obvously incorrect, since integral of insolation does not change for more than 0.1 % during eccentiricity variations.

Those are paced by orbital variations, which have nothing to do with solar activity.

[Response: I presumed you meant short term variations in the orbital parameters (which we don't include).

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.

Increasing CO2 does increase the greenhouse effect, but there are other factors which determine climate, including solar irradiance, volcanism, albedo, orbital variations, continental drift, mountain building, variations in sea currents, changes in greenhouse gases, even cometary impacts.

First, orbital tuning can increase the response by matching the signal times, but there's a limit to how far it can go — it simply can't inflate the physical amplitude of the response, which dominates the period analysis once the tuning is done, and it certainly can't impose temporal variations in the physical amplitude of the response.

You must have failed to notice Coby that in those articles I link to (* & 312) I do mention that ONE «oscillator» is a TRIVARIATE of planetary orbital variation, planetary axial precession and Solar Climate as concerned with TOTAL, and Spectral division of, Solar energy output.

I do recall that proposed physical causes for abrupt climate change include orbital variations and combinations of feedbacks... and none of this negates the different drivers / modeling approaches for weather systems versus climate.

Therefore, while past periods of temp / CO2 rise may tell us something about feedback (orbital variation can not account for the total temperature rise during interlgacials), they do not tell us what happens if the CO2 increase precedes temperature increases.
