Saltier Atlantic and Global Warming
Again the complexity of climate change becomes apparent. Sub-systems in the global climatic system may shift to another state – leading to highly variable regional changes in climate. In this case, changes in the saltiness of the Atlantic may lead to colder temperatures in Europe and New England. This is entirely consistent with what has perhaps been misdescribed as “global warming” on the basis of a higher average global temperature. However, it appears to be emerging that greater variability and climatic extremes in multiple directions (hotter or colder, wetter or drier) is at least as serious of threat to global ecological sustainability and human societies.

Researchers announced yesterday that the tropical Atlantic Ocean is much saltier than it was 50 years ago, a discovery that may help shed light on a poorly understood climate system that could have implications for global warming.
