James Hansen, a former NASA scientist dubbed the “godfather” of global warming, has a new study out claiming future warming could be worse than predicted, with the world suffering through massive sea level rise and super storms.
Hansen’s global warming doomsday scenario suffers from one (well, at least one) major flaw: it depends on a slowdown of Atlantic overturning circulation, which transports warm water from the tropics to the North Atlantic where it warms the atmosphere.
Hansen and his co-authors list a “slowdown and eventual shutdown of the Atlantic overturning circulation with cooling of the North Atlantic region” as one of five impacts man-made global warming would have on the planet.
A new study debunks claims made by Hansen, Rahmstorf and Mann that man-made warming will slow the AMOC or even completely shut it down.
“Claims of strengthening or reducing of the AMOC are therefore pure speculation,” Aussie scientists wrote in their recently published paper.
The Aussie scientists specifically refuted the study by Rahmstorf and Mann claiming ice melt was slowing the AMOC based on climate models and proxy data. That study directly contradicted actual measurements of the AMOC taken by oceanographer Thomas Rossby of the University of Rhode Island.
