BBC Climate Explainers Recycle Yesterday’s “The Day After Tomorrow”

The CHIMP5 model simulation showed that the wind created by legions of flying monkeys may also be behind the slowdown behind the slowdown – or did I just watch the Day After the Wizard of Oz on YouTube? Who let Hollywood script writers loose on the climate science community? 😉

Yesterday’s “The Day After Tomorrow” climate explainer’s excuse for cold winters is back – research suggests that the North Atlantic current is weaker than anytime for the last 1000 years

Climate change dials down Atlantic Ocean heating system

A significant shift in the system of ocean currents that helps keep parts of Europe warm could send temperatures in the UK lower, scientists have found.

They say the Atlantic Ocean circulation system is weaker now than it has been for more than 1,000 years – and has changed significantly in the past 150.

The study, in the journal Nature, says it may be a response to increased melting ice and is likely to continue.

Researchers say that could have an impact on Atlantic ecosystems.

Scientists involved in the…

  1. From the AP link OB shared above [I’ve added a correction for serial alarmist Rahmstorf – 😉]
    The specific trend pattern we found in [computer model] measurements looks exactly like what is predicted by computer simulations as a result of a slowdown in the Gulf Stream System, and I see no other plausible explanation for it,” Rahmstorf, whose study relied on proxy-data from ocean sediment and calcareous shells, said.

    It’s clear that the circulation is weakening, said Colorado State hurricane expert Phil Klotzbach, who wasn’t part of the studies. Decades ago, that would have meant weaker Atlantic hurricane activity, but that hasn’t been happening and it could mean there is a difference in weakening in winter and summer, he said.

    Andreas Schmittner at Oregon State University, who also wasn’t part of the studies, said the Potsdam group’s analysis makes sense, adding that as the world emits more greenhouse gases from the burning of fossil fuels, we can expect it to slow further.

    But MIT’s Carl Wunsch said that the paper’s “assertions of weakening are conceivable, but unsupported by any data.”

    And Kevin Trenberth of the National Center for Atmospheric Research said his recent work faults regular cycles in the atmosphere more than the ocean. He said the Potsdam study doesn’t explain year to year variability, while atmospheric cycles do.

    Rahmstorf said his study averages data over a decade at a time to render year-to-year changes less meaningful. The work shows that it is ocean circulation that drives the changes in atmosphere, not the other way around, he said.

    Scientists relied on climate models, not direct measurements, to claim in a new study man-made global warming caused a slowdown in the Gulf Stream ocean current.
