Scientists have discovered that the Atlantic Ocean current that keeps northern latitudes warm may be more unstable that they previously thought.
Yale University researchers have found that Atlantic Meridional Overturning Circulation — the same deep-water ocean current featured in the movie ‘The Day After Tomorrow’ — could occur quite abruptly. Not as abruptly as the few weeks the movie covers admittedly but the effects of it occurring at all would have a major effect on the climate in northern latitudes.
The Maunder and Dalton Minimums were periods in history where the winters in Europe were bitterly cold for months on end and the summers were cooler and wetter than they are now. both periods, but more so the Maunder Minimum brought many hardships to the period known as The little ice Age.
The Yale research states:
“We show that the possibility of a collapsed AMOC under global warming is hugely underestimated,” said Wei Liu, a postdoctoral associate in the Department of Geology and Geophysics at Yale University and lead author of the study.
“In current models, AMOC is systematically biased to be in a stable regime,” Liu said. “A bias-corrected model predicts a future AMOC collapse with prominent cooling over the northern North Atlantic and neighboring areas. This has enormous implications for regional and global climate change.” (source)
This isn’t the only evidence that we could be heading into a major cooling period in the near future. As far back as 2008 Professor Emeritus of Geology at Western Washington University, Don Easterbrook made the case for a period of deep cold in the coming decades.
The PDO cool mode has replaced the warm mode in the Pacific Ocean, virtually assuring us of about 30 years of global cooling, perhaps much deeper than the global cooling from about 1945 to 1977. Just how much cooler the global climate will be during this cool cycle is uncertain. Recent solar changes suggest that it could be fairly severe, perhaps more like the 1880 to 1915 cool cycle than the more moderate 1945-1977 cool cycle. A more drastic cooling, similar to that during the Dalton and Maunder minimums, could plunge the Earth into another Little Ice Age, but only time will tell if that is likely. (source)
Livingston and Penn have also written extensively on a period of global cooling in our future, their research based on sunspot and the energy output of the sun. In short the lower the number of sunspots the cooler it gets…and they predict almost zero sunspots for years in the very near future. David Hathaway a NASA solar physicist unconnected with their research thinks they have a point.
Northumbria University professor Valentina Zharkova agrees with them.
Valentina Zharkova said fluctuations an 11-year cycle of solar activity the sun goes through would be responsible for a freeze, the like of which has not been experienced since the 1600s.
From 1645 to 1715 global temperatures dropped due to low solar activity so much that the planet experienced a 70-year ice age known as Maunder Minimum which saw the River Thames in London completely frozen.
The researchers have now developed a “double dynamo “model that can better predict when the next freeze will be.
Based on current cycles, they predict solar activity dwindling for ten years from 2030.
Professor Zharkova said two magnetic waves will cancel each other out in about 2030, leading to a drop in sun spots and solar flares of about 60 per cent. (source)
If we are heading for a grand minimum that causes far lower temperatures than we are used to we need to know about it. As more and more scientists come out and say the science of global warming is flawed governments need to be preparing for a cooling world and the problems that extended periods of severe cold and snowy weather will bring. As individuals we need to be looking at how our lives would be affected by such conditions.
