The video on the right was made by superimposing all January SST images, from 1982 to 2010. The recent decrease in SSTs along the SE coast of the United States - one of the few large areas in the Atlantic that has significantly cooled - is clearly visible. An hypothetical decrease in the strength of the Gulf Stream is not apparent. Rather, SSTs images suggest that the gradient between the colder waters inshore and the warmer waters offshore has increased in the last years. In the late 2000s, the influence of the Gulf Stream has been particularly strong offshore, which has been accompanied by a inshore penetration of cold water along the coasts of N Florida, Georgia and the Carolinas.
