“Until now, no one has been able to demonstrate a physical link to what is causing these observed Atlantic Ocean fluctuations, so it was assumed they must be caused by natural variability,” lead study author Ben Booth, a climate processes scientist at the MET Office, said in a statement. “Our research implies that far from being natural, these changes could have been largely driven by dirty pollution and volcanoes.” 

 

Using a computer climate model, Booth and his colleagues looked at sea-surface temperatures in the North Atlantic between 1860 and 2005. The model, which simulates physical processes in Earth’s atmosphere, reproduced these warm-cold variations in the North Atlantic. The simulations actually showed a clear link between the temperature changes in the Atlantic Ocean and the peaks and troughs in industrial pollution from surrounding countries.

 

Results showed that industrial aerosols and volcanic activity (to a lesser extent) could explain about 75 percent of these sea-surface temperature variations. - Is industrial pollution causing natural disasters?
