This idea was based on the 1815 eruption of Mt. Tambora which caused mass starvation and misery.
“Upper winds distributed the gas and suspended particles around the world. The aerosols reduced solar radiation and led to a global cooling. The winter of 1815/16 was one of the coldest of the millennium. Glaciers expanded. Torrential rains caused flooding in China and India. In Europe and North America, 1816 became the ‘year without a summer’.1 In many parts of the world, 1817 became the ‘year of famine’”
Wolfgang Behringer. “Tambora and the Year without a Summer”
“On some great and glorious day the plain folks of the land will reach their heart’s desire at last, and the White House will be adorned by a downright moron.”
According to the New York Times, if the winter is warm, that is due to global warming. And if winter weather is cold, that is also due to global warming.
