Sentences with phrase «for ice sheet growth»

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.

Not exact matches

Subtracting one from the other produced a «mass - balance» picture of net ice loss or growth for each ice sheet.

To track the growth and retreat of ice cover in the region, Miller and colleagues have been hunting for remnants of scraggly mosses along the edges of the island's retreating ice sheets.

Repeated Pleistocene Epoch ice ages covered much of North America, Europe and Asia under mile - thick ice sheets that denuded continents, stunted plant growth, and dropped ocean levels 400 feet for thousands of years.

Jimmy dear will find that it is one possible explanation for the Younger Dryas — AMOC won't stop entirely but the associated high northern cooling brings with it ice sheet growth and sea level falls.

Simulating the variation of the ice sheet's albedo using a regional climate model — Modèle Atmosphérique Régionale (MAR), which some members of the team helped develop — indicated that increasing temperatures and melting accompanied by snow grain growth and greater bare ice exposure account for about half the decline, the scientists report.

When there is evidence for the growth of a large ice sheet on Antarctica or on Greenland or the growth of sea ice in the Arctic Ocean, we see evidence for a dramatic change in carbon dioxide levels over the last 20 million years.

The growth and decay of continental ice sheets represents a slow feedback operating over millennia; if one is concerned with the more rapid response of the climate to CO2, ice sheets have to be accounted for as a major forcing.

A CO2 pulse in the atmosphere will take centuries to finally return to original levels, and that is completely ignoring any potential feedbacks from other parts of the system (ie temperatures raised for centuries could result in massve methane releases and loss of signficant low albedo ice sheets etc.) The experiments I am aware of that show improved plant growth in elevated CO2 levels require that all additional biological needs are amply provided for.

A lowering of atmospheric carbon dioxide levels near the beginning of this time period occurred in response to the rise of land plants and likely cooled Earth, but the rapid growth of extensive Gondwanan ice sheets was delayed for tens of millions of years, until the Late Mississippian.»

One possible explanation for the Younger Dryas is freshwater melt inflow — AMOC won't stop entirely but the associated high northern cooling brings with it ice sheet growth and sea level falls.

The Cenozoic record also reveals the amplification of climate change that occurs with growth or decay of ice sheets, as is apparent at about 34 Myr BP when the Earth became cool enough for large - scale glaciation of Antarctica and in the most recent 3 — 5 Myr with the growth of Northern Hemisphere ice sheets.

Superimposed on the long - term trends, in addition to occasional hyperthermals, are continual high - frequency temperature oscillations, which are apparent in figure 1 after 34 Myr BP, when the Earth became cold enough for a large ice sheet to form on Antarctica, and are still more prominent during ice sheet growth in the Northern Hemisphere.
