Plant ice production in New York doubled between 1900 and 1910 and, by 1914, 26 million tons (23 billion kg) of plant ice was being produced in the U.S. each year in comparison to the 24 million tons (22 billion kg) of naturally harvested ice. [132]
The timeline of glaciation covers ice ages specifically, which tend to have their own names for phases, often with different names used for different parts of the world. The names for earlier periods and events come from geology and paleontology .
A less severe cold period or ice age is shown during the Jurassic-Cretaceous (150 Ma). There have been five or six major ice ages in the history of Earth over the past 3 billion years. The Late Cenozoic Ice Age began 34 million years ago, its latest phase being the Quaternary glaciation, in progress since 2.58 million years ago.
Domestic production and sales were the largest single market source for ice in America and Europe. From the 1850s onwards ice cutting took on large-scale industrial proportions in Germany with Berlin as a key market. [8] In the 1880s, New York City had over 1500 ice delivery wagons and Americans consumed over 5 million tons of ice annually. [9]
A chronology of climatic events of importance for the Last Glacial Period, about the last 120,000 years The Last Glacial Period caused a much lower global sea level.. The Last Glacial Period (LGP), also known as the Last glacial cycle, occurred from the end of the Last Interglacial to the beginning of the Holocene, c. 115,000 – c. 11,700 years ago, and thus corresponds to most of the ...
A glacial period (alternatively glacial or glaciation) is an interval of time (thousands of years) within an ice age that is marked by colder temperatures and glacier advances. Interglacials, on the other hand, are periods of warmer climate between glacial periods. The Last Glacial Period ended about 15,000 years ago. [1]
It wasn’t until the Age of Exploration, when White Europeans colonized the Americas, that modern ice cream made its debut. “The Spanish Empire was the first European group to colonize the ...
The following is a timeline of low-temperature technology and cryogenic technology (refrigeration down to close to absolute zero, i.e. –273.15 °C, −459.67 °F or 0 K). [1] It also lists important milestones in thermometry , thermodynamics , statistical physics and calorimetry , that were crucial in development of low temperature systems.
