WebMar 26, 2024 · But a new study of the current's strength over the past half-million years suggests global warming may not shut down the current any time soon, as some scientists fear. Instead, it could trigger a replay of ancient events, when multiple bouts of warming caused rapid, centurylong swings in the current's strength, sowing climate chaos that may … WebGlobal climate change could disrupt the global conveyer belt, causing potentially drastic temperature changes in Europe and even worldwide. The global conveyor belt is a strong, but easily disrupted process. Research suggests that the conveyor belt may be affected by climate change. If global warming results in increased rainfall in the North ...
WebJan 16, 2010 · The integrated assessment model FUND 2.8n is applied in an assessment to estimate the magnitude of the general market and non-market impacts of temperature changes caused by a possible shutdown of the thermohaline circulation (THC).

From Chapter 4, As the greenhouse effect continues to warm the planet slowly, the glaciers of Greenland are melting at a rapid rate. Scientists are concerned that this melting may dilute the salt water in that region of the ocean enough to shut down thermohaline circulation. Use what you know about climate to answer the following questions.
WebDec 19, 2013 · Thermohaline circulation, the large-scale movement of surface water through the world’s ocean basins, in latitudes near the poles is sensitive to temperature but even more so to salinity, so the larger concern in the North Atlantic Ocean comes from ice melt from the Greenland ice sheet and other sources of ice in the Arctic. The current melt rate …
