Previously, it has been held that carbon dioxide in the atmosphere was the cause of the ocean being fertilised, as rising levels brought climatic changes, washing more nutrients into the sea.
These climatic changes had great impacts on Qinghai Lake level and runoffs in this watershed.
Authigenic carbonate oxygen and carbon isotope evidence in lake sediment is an important proxy to reflect lake environment and climatic change.
This reveals that there occurred a great transient climatic change from the warm-humid one to dry-hot one then.
It does convey the information that climatic changes on both the Loess Plateau and in the polar area were all greatly influenced by global climatic variation.
Because of climatic changes and new tectonic movements, several sea and land evolutions occurred in the Bohai sea area to result in the formation of subsurface brine.
Water also has an extraordinary capacity to mop up heat, and this helps smooth out climatic changes that could otherwisedevastate ecosystems.
