How could we possibly chart its history? The Greenpeace website cites ice core data as backing them up (what? no references? :rofl:), but then we would have to have some gas isotope ratio that is used to pin down some quality.
They found that the coldest interval occurred when the overturning circulation collapsed following the discharge of icebergs into the North Atlantic 17,500 years ago. This regional climatic extreme began suddenly and lasted for two thousand years.
The lowermost radiocarbon date, immediately above the till, indicates that Lake Kullatorpssjo¨n was deglaciated before 14 000 14C yr BP, which corresponds to more than 17 200 cal. yr BP and provides further evidence that the Kullen Peninsula belongs to the earliest deglaciated area in
Sweden.
The thermohaline circulation is a global ocean current system that plays a crucial role in regulating Earth's climate. It is driven by differences in temperature and salinity, and helps distribute heat and nutrients around the world.
The thermohaline circulation helps regulate Earth's climate by transporting warm water from the equator to the poles and cold water from the poles to the equator. This helps maintain a more stable global climate and prevents extreme temperature changes.
The two main factors that influence the thermohaline circulation are temperature and salinity. Differences in these properties cause water to sink or rise, creating the ocean currents that drive the system.
Scientists believe that the thermohaline circulation has varied throughout Earth's history due to natural climate cycles. However, recent research suggests that human activities, such as global warming and melting polar ice caps, may be slowing down the circulation.
If the thermohaline circulation continues to slow down, it could have significant impacts on global climate patterns. This could lead to changes in ocean temperatures, sea levels, and weather patterns, which could have serious consequences for both human populations and marine ecosystems.
