Sentences with phrase «ice sheet growth»

Such as sea levels changing as a result of ice sheet growth or reduction in the northern hemisphere.

Orbital conditions now are, indeed, conducive (albeit weakly6) to initiation of ice sheet growth in the Northern Hemisphere But only a small amount of human - made GHGs are needed to overwhelm any natural tendency toward cooling.

«Our findings suggest a significant link between ice sheet growth, the monsoon and the closing of the Panama Seaway, as North and South America drifted closer together.

The study, co-authored by Dr Thomas Stevens, from the Department of Geography at Royal Holloway, University of London, found a previously unknown mechanism by which the joining of North and South America changed the salinity of the Pacific Ocean and caused major ice sheet growth across the Northern Hemisphere.

Precipitation: increased freshwater / iceberg flux cools ocean mixed layer, increases sea ice area, causing increase of precipitation that falls before it reaches Antarctica, adding to ocean surface freshening and reducing ice sheet growth.

Scientists: Warming causes Antarctic ice sheet growth, and lower sea levels By Kenneth Richard While many scientists are projecting rapid sea level rise as a result of a warmer Antarctica and consequent ice sheet melting, other scientists are projecting that the surface of the Antarctic ice sheet will gain in mass because a warmer Antarctica means snow and ice accumulation will outpace the -LSB-...]

Peter Weyl hypothesized in 1968 that the closure of the Central American Seaway and the intensification of the Gulf Stream would have brought a critical ingredient for ice sheet growth to the Northern Hemisphere — moisture.

The mechanism for high - amplitude glacio - eustasy has been linked to astronomically forced ice sheet growth and decay2, 42,43,44.

A positive feedback loop was established, with cooling leading to ice sheet growth and sea level lowering, which encouraged further ice sheet growth and cooling [26, 27].

The empirical data show that deep ocean cooling slows relative to global mean surface cooling as the area of ice and snow on the surface expands, consistent with the fact that the increase of δ18O between the Holocene and LGM was due more to ice sheet growth than to deep ocean cooling.»

If he is talking about glaciers and polar ice caps, not sea ice, which can grow any time under appropriate short - term conditions, then not for over 400,000 years have orbital conditions been LESS conducive to ice sheet growth.

These preconditions — moisture plus an Arctic nucleus for cooling — would have made the climate system highly susceptible to ice sheet growth.
