According to the art historian Hermann Beenken, Friedrich painted winter scenes in which "no man has yet set his foot".
The conversion of sulfur dioxide to sulfuric acid, which condenses rapidly in the stratosphere to form fine sulfate aerosols. A volcanic winter is a reduction in global temperatures caused by droplets of sulfuric acid obscuring the Sun and raising Earth's albedo (increasing the reflection of solar radiation) after a large, sulfur-rich, particularly explosive volcanic eruption.
Hard rime forms by rapid freezing of supercooled water under at least moderate wind conditions. The droplets freeze more or less individually, leaving air gaps. [4] [3] Clear ice forms by slow freezing of supercooled water. Clear ice is typically transparent and homogeneous. Its amorphous and dense structure makes it adhesive.
The winter of 1904 was the coolest year on record worldwide. [19] 1912. January 1912 cold wave – The severe 1912 United States cold wave caused the longest recorded period of weather below 0 °F or −17.8 °C. 1916-1917.

In the history of artificial intelligence, an AI winter is a period of reduced funding and interest in artificial intelligence research. [1] The field has experienced several hype cycles , followed by disappointment and criticism, followed by funding cuts, followed by renewed interest years or even decades later.
Some were underground chambers, usually man-made, close to natural sources of winter ice such as freshwater lakes, but many were buildings with various types of insulation. During the winter, ice and snow would be cut from lakes or rivers, taken into the ice house, and packed with insulation (often straw or sawdust). It would remain frozen for ...
