Records of ice cores from Greenland has showed that circulation shut down during the last ice age. This caused a 7 degree celsius decrease in temperature in Greenland. When the ice caps receded and circulation resumed, Greenland warmed back up. With temperatures rising due to global climate change, an increase in fresh water from melting glaciers and ice caps could reduce the salinity of the ocean, shutting down thermohaline circulation again.]]> 2019-04-12 18:04:08 UTC https://padlet.com/sfarrens7525/cl4fwey004lh/wish/351265378 ahoxie6467 https://padlet.com/sfarrens7525/cl4fwey004lh/wish/351268646 Thermohaline circulation is a natural process in which ocean currents, moved by wind and changes in density move heat energy throughout the ocean. Warm, tropical waters are moved towards the poles by wind. When the water reaches the poles, it cools and sinks below the less salty, less dense water. This cycle brings heat energy to Europe, which is why places like Britain have a more temperate climate than areas on the same latitude. Conversely, cooler waters are moved towards the equator, causing more temperate climates in areas like the U.S. Eastern seaboard.]]> 2019-04-12 18:12:18 UTC https://padlet.com/sfarrens7525/cl4fwey004lh/wish/351268646 sfarrens7525 https://padlet.com/sfarrens7525/cl4fwey004lh/wish/351753524 As a result of the thermohaline circulation shutdown, widespread cooling over the North Atlantic and Western Europe would ensue. There would be increased sea ice in the U.S., stronger storms, and changes precipitation in both the North Atlantic and Europe, which would affect river flow, and therefore reduced crop productivity. Europe's climate would drastically become colder, for the T.H.C. provides warm air.]]> 2019-04-15 17:54:25 UTC https://padlet.com/sfarrens7525/cl4fwey004lh/wish/351753524 ahoxie6467 https://padlet.com/sfarrens7525/cl4fwey004lh/wish/351753692 There is a lot of debate about the timeline of the shutdown of thermohaline circulation. Data from NASA in 2010 suggested that it might actually have sped up slightly since 1993. A 2015 study suggests that circulation has weakened by 10-20% in the past 200 years. However, scientists believe an irreversible shutdown of thermohaline circulation is a product of models rather than a likely outcome of global climate change.]]> 2019-04-15 17:54:55 UTC https://padlet.com/sfarrens7525/cl4fwey004lh/wish/351753692 lkutac8027 https://padlet.com/sfarrens7525/cl4fwey004lh/wish/351756959 2019-04-15 18:02:30 UTC https://padlet.com/sfarrens7525/cl4fwey004lh/wish/351756959
