Global Warming Is Slowing Ocean Currents Causing Dire Consequences, Warns Climate Expert Michael Mann

Climate

Climate scientists Michael Mann and Stefan Rahmstorf announced the findings of their new study yesterday, which shows that the rapid melting of the polar ice has slowed down currents in the Atlantic Ocean, particularly since 1970. The scientists say "the slowdown in ocean currents will result in sea level rise in cities like New York and Boston, and temperature changes on both sides of the Atlantic," reports NPR's Jeremy Hobson. Mann, who is a professor and the director of the Earth System Science Center at Penn State University, joined Hobson yesterday on Here and Now to discuss the study and the implications of its findings.

Not only would North America and Europe experience colder temperatures, but "If those current systems shut down, then suddenly the North Atlantic [fisheries] would no longer be productive," says Michael Mann.

Mann explains the consequences of the Gulf Stream shutting down and how it would drastically alter the climate in Europe and North America. The last time this happened, about 12,000 years ago, at the end of the last ice age, North America and Europe went back into a mini-ice age, Mann says. Not only would North America and Europe experience colder temperatures, but "If those current systems shut down, then suddenly the North Atlantic [fisheries] would no longer be productive," says Mann.

Mann says a shutdown of the Gulf Stream might happen a lot sooner than the latest Intergovernmental Panel on Climate Change (IPCC) report predicts. "Our studies suggest we are much closer to that than the current model suggests. A full shutdown ... could be decades from now."

Investment in U.S. offshore wind projects are set to hit $78 billion (€69 billion) this decade, in contrast with an estimated $82 billion for U.S. offshore oil and gasoline projects, Wood Mackenzie data shows. This would be a remarkable feat only four years after the first offshore wind plant — the 30 megawatt (MW) Block Island Wind Farm off the coast of Rhode Island — started operating in U.S. waters.

The COVID-19 pandemic has revealed both the strengths and limitations of globalization. The crisis has made people aware of how industrialized food production can be, and just how far food can travel to get to the local supermarket. There are many benefits to this system, including low prices for consumers and larger, even global, markets for producers. But there are also costs — to the environment, workers, small farmers and to a region or individual nation's food security.
