Sentences with phrase «when changes in ocean circulation»

Sensitivity experiments show that atmospheric CO2 closely follows decadal - mean temperature changes when changes in ocean circulation and ocean - sediment interactions are not important.

Not exact matches

The goal is to capture natural variations in the climate, like changes in ocean circulation or features like the El Niño Southern Oscillation, that are swamped by the signal of human - caused warming when looking out to the end of the century.

In the paper Gray makes many extravagant claims about how supposed changes in the THC accounted for various 20th century climate changes («I judge our present global ocean circulation conditions to be similar to that of the period of the early 1940s when the globe had shown great warming since 1910, and there was concern as to whether this 1910 - 1940 global warming would continuIn the paper Gray makes many extravagant claims about how supposed changes in the THC accounted for various 20th century climate changes («I judge our present global ocean circulation conditions to be similar to that of the period of the early 1940s when the globe had shown great warming since 1910, and there was concern as to whether this 1910 - 1940 global warming would continuin the THC accounted for various 20th century climate changes («I judge our present global ocean circulation conditions to be similar to that of the period of the early 1940s when the globe had shown great warming since 1910, and there was concern as to whether this 1910 - 1940 global warming would continue.

You've got the radiative physics, the measurements of ocean temperature and land temperature, the changes in ocean heat content (Hint — upwards, whereas if if was just a matter of circulation moving heat around you might expect something more simple) and of course observed predictions such as stratospheric cooling which you don't get when warming occurs from oceanic circulation.

The paleoclimate record (8.2 kyr, and earlier «large lake collapses») shows a dramatic drop in surface temperatures for a substantial period of time when the ocean circulation shuts off or changes, but is that actually what would be expected under these warming conditions?

For weather predictions, accuracy disappears within a few weeks — but for ocean forecasts, accuracy seems to have decadal scale accuracy — and when you go to climate forcing effects, the timescale moves toward centuries, with the big uncertainties being ice sheet dynamics, changes in ocean circulation and the biosphere response.

This thesis presents the results of several general circulation model simulations aimed at studying the effect of ocean circulation changes when they occur in conjunction with increased atmospheric trace gas concentrations.

The new study explores what happened to ocean circulation when the Earth went through a series of abrupt climate changes in the past, during a time when ice covered part of North America and temperatures were colder than today.

The most likely candidate for that climatic variable force that comes to mind is solar variability (because I can think of no other force that can change or reverse in a different trend often enough, and quick enough to account for the historical climatic record) and the primary and secondary effects associated with this solar variability which I feel are a significant player in glacial / inter-glacial cycles, counter climatic trends when taken into consideration with these factors which are, land / ocean arrangements, mean land elevation, mean magnetic field strength of the earth (magnetic excursions), the mean state of the climate (average global temperature), the initial state of the earth's climate (how close to interglacial - glacial threshold condition it is) the state of random terrestrial (violent volcanic eruption, or a random atmospheric circulation / oceanic pattern that feeds upon itself possibly) / extra terrestrial events (super-nova in vicinity of earth or a random impact) along with Milankovitch Cycles.

When a full - depth ocean model is used, something intriguing happens: the loss of Arctic sea ice triggers a far - flung response that mimics climate change itself, including a slowdown of the Atlantic Meridional Overturning Circulation (AMOC), a build - up of heat in the tropical oceans over several decades, and a warming of the atmosphere a few miles above the tropics.
