“Years Without Summer” for the Northern Hemisphere

According to climate scientists, humanity is in a state of gradual climate catastrophe, which will bring a new great famine in the Northern Hemisphere due to this climate change that occurs due to changes in the magnetic field of the sun and not due to human intervention. from carbon dioxide emissions cited by scientists working with the UN (please read the analysis entitled «Climate Change is due to the Action of the Sun and not to Carbon Dioxide Emissions»).

The historical phenomenon of the “Year without Summer”

The phenomenon of “Year without summer” has historically been experienced by humanity once. In 1815, Tambora volcano in Indonesia and then the Dutch East Indies erupted, spewing huge amounts of ash into the upper atmosphere. The estimated volume of ejection material was about 160km3, with this eruption being the largest volcanic eruption in history.

The ejected ash engulfed the planet and without sunshine the temperature dropped dramatically. This caused the greatest famine of the 19th and 20th centuries due to natural phenomena. The disasters in wheat, oats and potato crops have been devastating, causing an unprecedented food crisis. Raids on grain warehouses and bakeries were commonplace, while looting and riots wreaked havoc in European cities.

That year global temperatures dropped by 0.4-0.7 degrees Celsius and food shortages across the northern hemisphere – crops destroyed by frost and lack of sunshine – led to famine, death, and social unrest.

It is very likely that the phenomenon “Year without summer” will appear starting from the decade we are going through and until 2050-2100, only in this case the nightmare can be for years and not for a year, i.e., “Years without Summer”.

In this case in the Northern Hemisphere and especially in Europe will appear prolonged famines, diseases, migrations of large populations, desertification, social conflicts bringing to the fore the last decades of the Middle Ages.

The scenario that the cold can persist and continue from one decade to the next and in addition, the temperature drop of more than one degree is enough to lead to the conclusion that the countries of the northern hemisphere will end up with an unappreciated magnitude of social and economic crisis.

Climate scientists know that global warming has pushed the desert south of Syria for the past thirty years, displacing more than a million farmers who no longer have land to cultivate.

AMOC: The temperature regulator of the Earth’s Northern Hemisphere

The Gulf Stream is a deep ocean current (scientifically known as the Atlantic Meridional Overturning Circulation-AMOC) that carries the warm waters of the South Pacific below the southern tip of Africa and then continues to the east coast of South and North America and West Europe.

The Gulf Stream sends millions of tons of hot water per minute to an end point just south of Greenland and west of Britain. In this region much of the water heat rises into the atmosphere to warm Europe. The cool, salty sea water ends up deep in the ocean to return years later to the South Pacific.

The Gulf Stream carries warm, surface waters from the Atlantic to the Arctic. In its course, this water stream heats the air to large geometric widths and then cooling, it sinks and emerges again at the equator, where it circulates as a stream at shallower depths.

This system is called thermohaline circulation because it works both from the temperature and from the sudden increase in the salt content of the water in this area as it loses heat in the North Atlantic. Fresh water freezes at a higher temperature than the corresponding seawater.

This system provides the same weather conditions in London and Amsterdam (Northwest Europe) and in Calgary and Edmonton, Canada. Britain, Germany, the Netherlands, Poland, and Scandinavia are about the same latitude as the region from central Canada to Alaska.

The only element that provides them with temperatures suitable for rich crops if compared to Alaska, is the heat distributed by the Gulf Stream (AMOC).

The main regulator of the continuous movement of AMOC is the highest degree of salt content of the waters in the North Atlantic region, as AMOC gives heat to the air of Europe. Since highly saline water is much denser and heavier than normal seawater, it sinks into the deeper waters of the ocean, pulling the rest of the AMOC behind it and thus helping to maintain the flow of the AMOC.

If for some reason this area starts receiving fresh water it will dissolve the highest degree of salt contained in the AMOC waters in this area, resulting in a decrease in the density of the salt water, causing a reduction in the flow-deceleration of the transfer current, causing a reduction in Europe’s main heat source.

This Ugly Scenario is in progress

This scenario is already being studied by scientists working on climate change in both Antarctica and off the coast of Greenland due to melting glaciers.

In April 2021, climate scientists found that eight of Antarctica’s largest glaciers were showing signs of disintegration.

Melting ice in Antarctica

Part of the AMOC moves around Antarctica. Due to global warming, Antarctica supplies hundreds of billions of tons of icy freshwater to the ocean each year – which in turn dilutes and cools seawater while reducing the flow of water.

This situation therefore hinders the process described above in which the cold and salty water of the ocean sinks below the surface of the sea in winter.

At the same time, the northern part of the AMOC, which is warming Europe, is experiencing a problem in the North Atlantic, as the melting glacier of Greenland is dumping hundreds of billions of tons of cold fresh water, due to global warming.

The problems in the AMOC started from the time of the Industrial Revolution (studies of the University of London and Woods Hole Oceanographic Institution) with the present time increasing the speed of its disturbance making it approach the break-even point where after that it will lead to collapse


NASA scientists told the Thermohaline Circulation that “without the enormous heat generated by these ocean currents – which equates to generating electricity for one million nuclear power plants – Europe’s average temperature will drop by 5oC to 10oC. “Such a drop refers to the average global temperatures towards the end of the last ice age about 20,000 years ago.”
