There is an article titled "Slowing Gulf Stream Current to Boost Warming for 20 Years," written by Matt McGrath on July 19, 2018, that exposes the concerns of environmental scientists about the issue of how the gulf stream is slowing down and the effects this could have in the short and medium terms.
