Natural changes in seawater is causing global climate change according to a new study. So what are the Greens going to do about that? Drain the Pacific Ocean?
Natural changes in seawater chemistry are a key cause of climate change, a new study suggests.
Experts at the University of Toronto and the University of California Santa Cruz have found that the impact of continental collisions and divisions over millions of years has a major impact on global warming.
The geological activity causes the dissolution or creation of massive gyspum deposits which scientists have found alters the sulphate content of the ocean and the atmosphere. That in turn affects the climate.
Researchers believe that “times of high sulphate concentrations in ocean water correlate with global cooling, just as times of low concentration correspond with greenhouse periods”.
Professor Ulrich Wortmann, of the Department of Earth Sciences at the University of Toronto and lead author of the study, said: “While it has been known for a long time that gyspum deposits can be formed and destroyed rapidly, the effect of these processes on seawater chemistry has been overlooked.
“The idea represents a paradigm shift in our understanding of how ocean chemistry changes over time and how these changes are linked to climate.”
