Rising Sea-Levels May Have Forced Vikings to Leave Greenland, Shows Study
By Ashmita Gupta17 January, 2022TWC India
What could have possibly driven out the mighty Vikings?
There are, of course, several theories attached to their perplexing disappearance, but the most conceivable hypothesis is climate change. New findings point to ice sheet growth and sea-level rise as the causative agents of massive coastal flooding that inundated Norse farms and ultimately led them to desert the region.
“The literature suggests that Viking out-migration was forced by the climatic shift from the Medieval Warm Period (~900-1350 AD) to the Little Ice Age (~1350-1850 AD) when environmental conditions became unfavourable for continued settlement,” reads the abstract of the presentation at AGU.
By sheer luck, when the Vikings first arrived in Greenland in the 10th century, the region was experiencing a warmer climate which allowed agriculture to flourish. And the group continued to enjoy this warmer climate for the next 500 years.
However, between the 14th and 19th centuries, Greenland experienced what is known as the "Little Ice Age".
Russia-Ukraine War: Potential “Nuclear Winter” Could Kill Billions, Transform the Entire Planet
By Deekshith Nevil Pinto01 March, 2022
The effects would be similar to what happened after the great 1815 Tambora volcanic eruption in Indonesia that triggered the infamous ‘Year Without a Summer’ in 1816 in the Northern Hemisphere. Killing frosts disrupted agriculture every month of the summer in New England, and the exceptionally cold and wet weather in Europe triggered widespread harvest failures, resulting in famine and economic collapse. While the cooling effect of that eruption only lasted about a year, a limited nuclear exchange would cause 5-10 consecutive "Years Without a Summer" and more than a decade of significantly reduced crop yields.
Reduced ocean circulation during the ice age caused anoxic conditions and increased carbon storage in the deep sea

Summary:
The movement of water masses in the ocean, its circulation, is an essential component of the global climate system. Researchers have now been able to show that circulation in the deep ocean was significantly slowed down during the last glacial period. Analyses of sediment samples show that the decomposition of organic carbon in the water masses of the deep sea consumed the oxygen available there.
Through analysis of ice cores from Greenland and Antarctica, a research team has found evidence of an extreme solar storm that occurred about 9,200 years ago. What puzzles the researchers is that the storm took place during one of the sun's more quiet phases -- during which it is generally believed our planet is less exposed to such events.
Human Expansion During Ice Age Could Explain How We Vanquished the Neanderthals
Groundbreaking discovery that humans in howling Ice Age cold as well supports the thesis that we bested the Neanderthals because we developed better adaptability
The first modern Homo sapiens to reach Europe more than 45,000 years ago faced much colder temperatures than had been thought, archaeologists have deduced – yet they slogged on and survived during one the peaks of the last Ice Age, a new study shows.
Weather has influenced significant events thorughout human history, whether forced migration or the course of a war.
Sometimes these events are tied to climate change, other times they represent anomalies that affected the future of air travel or launched eras of famine and disease. In the forthcoming list, Stacker examines dozens of ways weather has shaped human history, drawing on historical documents, newspaper articles, first-person accounts, and documented weather events.
Chinese scientist Shen Kuo was the first person to study climate. In his 1088 “Dream Pool Essays,” he ponders climate change after finding petrified bamboo in a habitat that wouldn't support such growth in his lifetime. Since then, inventions and technological advances have allowed people to track the weather over time and, in some instances, even control it.
Around 1602, Galileo was the first to conceptualize a thermometer that could quantify temperature, allowing people to track changes in heat. The air conditioner made its first appearance in 1902; and in 1974 the Senate Committee on Foreign Relations held a classified briefing on the results of Operation Popeye, a five-year cloud-seeding experiment designed to lengthen Vietnam's monsoon season, destabilize enemy forces there, and allow the U.S. to win the war.
But far more often than humanity seeks to control the weather, the weather does the controlling.
While weather refers to short-term atmospheric conditions (think of a forecast for how sunny and warm it will be next week), climate refers to long-term changes in overall weather trends over time (decades or hundreds of years). The two are impacted by each other. Climate change affects the severity and frequency of weather events, and the costs of extreme weather events rise as the effects of climate change become more apparent. With increased technology allowing for the tracking of weather trends over time and the anticipation and identification of potential weather hazards, people have been able to avert and prepare for some of nature's wildest expressions.

1692: Mini ice age instigates the Salem Witch Trials
The famous Salem Witch Trials between 1692 and 1693 ultimately resulted in more than 200 people being accused of practicing witchcraft and 20 people being put to death. Causes for the hysteria have been attributed to everything from socioeconomic issues in Salem to cold weather, which does overlap with periods of witch hunts throughout history.
1876: Famines form the 'Third World'
The term “Third World” was created during the Cold War to refer to development gaps across the globe due to income disparities and access. Many of these differences were most acutely shaped in the last quarter of the 1800s, particularly in 1876 when famines caused by El Niño drought brought utter destruction to crops in India's Deccan Plateau, across China, and in Brazil, Ethiopia, and other parts of the world.
1945: Kokura gets spared—twice
Sunshine over Hiroshima on Aug. 6, 1945, meant the skies were clear for the first nuclear weapon ever to be used in war to be dropped from overhead, killing 146,000 people over the course of the next four months and sparing Hiroshima's back-up target of Kokura.
Kokura dodged tragedy again just days later, when the second nuclear weapon was already loaded in a B-29 destined for the town but not dropped because of overcast skies, drifting smoke, and obscured visibility from coal tar being intentionally burned by the Yahata Steel Works. Low on fuel after several passes over the town, the bomb ended up being dropped over the backup city of Nagasaki on Aug. 9., where upwards of 80,000 people were killed.

1948: Air inversion in Donora, Pennsylvania
The Clean Air Act—among the most comprehensive air-quality bills throughout the world—was passed in 1963, following the 1955 signing of the Air Pollution Control Act. But the beginnings of such legislation came from Donora, Pennsylvania, where an “air inversion” in 1948 goes down in history as one of the worst air pollution disasters in the United States. It caused breathing issues for more than 40% of the 14,000-person population in the mill town.
Donora was home to U.S. Steel's Donora Zinc Works and American Steel & Wire plant, which together released high emissions of sulfur dioxide, fluorine, nitrogen dioxide, hydrogen fluoride, and other toxic gases into the air. On Oct. 27, 1948, that air got trapped by an inversion of warmer air containing the airborne toxins in cold air across the valley town. The fog quickly became a yellow smog that stayed heavy in the air for five days until heavy rains came and broke the spell.
All told, 20 Donorans died by November—and another 50 died from respiratory illnesses a month later. The deaths directly resulted in new pushes for clean air laws in Pennsylvania and throughout the United States.
Outsiders Weather and Ice Age Watch: ‘Coldest days on record’ prompt BOM ‘volte-face’

Sky News host Rowan Dean says cities around the country have experienced some of the “coldest days on record” – contrary to predictions made by the Bureau of Meteorology which said “nights are likely to be warmer than average for most of Australia”.
“Remember this forecast from the Bureau of Meteorology, firm believers in the concept of man-made global warming, back at the end of May, only five days before the official beginning of winter,” Mr Dean said.
“According to the ABC on May 27 the Bureau of Meteorology predicted, and I quote, that ‘Nights are likely to be warmer than average for most of Australia, and daytime temperatures are likely to be above average for many parts of Australia, especially those closer to the coast’.
‘So … how’s that prediction looking?

“Similarly in Canberra, home to the greatest concentration of climate cultist luvvies ever assembled in one city, also known as the Public Service, it feels, apparently, like it’s nearly minus 10 degrees.
