Sentences with phrase «by higher insolation»

The warm early - Holocene climate around Svalbard was driven primarily by higher insolation and greater influx of warm Atlantic Water, but feedback processes further influenced the regional climate.»

Not exact matches

A recent study on the GIS melt during the Eemian argues that temperature rise alone produced 55 % of the melt and the rest was caused by higher solar insolation and feedbacks.

For instance, the commentary piece by Eric Wolff references earlier deglaciations and points out that solar insolation may have increased in the boreal summer during the most recent event, but was still not as high as during previous deglacial intervals.

Ice ages are generally triggered by minima in high - latitude NH summer insolation, enabling winter snowfall to persist through the year and therefore accumulate to build NH glacial ice sheets.

Similarly, times with especially intense high - latitude NH summer insolation, determined by orbital changes, are thought to trigger rapid deglaciations, associated climate change and sea level rise.

The rapid 1940s retreat is linked to unusually high solar insolation and patterns of precipitation governed by the Atlantic Multidecadal and North Atlantic Oscillation.42, 43

Then that lowest atmosphere layer emit and a 50 - 50 split sends it half up and half down; and the up ward is again absorbed by a higher and now cooler layer; which in turn emits but now at a lower temperature; until finally some much higher and much cooler layer gets to emit radiation that actually escapes to space and that radiating temperature is the one that must balance with the incoming TSI insolation rate.

In the case of the 100 kyr ice age cycles, that forcing is high northern latitude summer insolation driven by predictable changes in Earth's orbital and rotational parameters — aka, Milankovitch theory — which has the intial effect of melting glaciers, thereby reducing albedo at those latitudes.

Regardless of the carbon source (s), it has been shown that the hyperthermals were astronomically paced, spurred by coincident maxima in the Earth's orbit eccentricity and spin axis tilt [17], which increased high - latitude insolation and warming.

When the greenhouse gas reradiates this LR radiation, some radiates back towards the surface which then heats up — to a higher temperature than caused by the initial insolation, and an increase in the thermal energy within the surface.

«The Milankovitch theory of climate change proposes that glacial - interglacial cycles are driven by changes in summer insolation at high northern latitudes [i.e., solar irradiance received].
