Document Summary
6 times of climate changes seen: sea level rise. Melting of glaciers and polar ice cap, thermal expansion of water (h2o, when heat is added, volumn of water is increasing) A prediction: harm coastal regions, maximum of 2m and minimum of 0. 2m in: eg. 1m increase: 14 miles of coastline in us lost solutions: adaptation and mitigation: ocean acidification: co2 is absorbed by waters. ph is diminishing. Carbonate ions are decreased, which is important for corals and seashells, they may dissolve when too acidic. Sea butterfly, zooplankton. (some crustaceans: do better in a bit more acid. ) Social vulnerability: how vulnerable humans are dependent on them: destruction of coral reefs: ocean temperature increased, and in el mino years water was really hot. When too hot, co-exist organisms leave coral reefs, if leave for more than 2 weeks, the coral bleaches and eventually dies. So we get layered records of pollen under water.
