[26] The Little Ice Age brought colder winters to parts of Europe and North America. Farms and villages in the Swiss Alps were destroyed by encroaching glaciers during the mid-17th century. [ 27 ] Canals and rivers in Great Britain and the Netherlands were frequently frozen deeply enough to support ice skating and winter festivals. [ 27 ]
At around 13,000 14C y.a., retreat of the the western and eastern North American ice sheets exposed an 'ice free' corridor linking Alaska to the land to the south. The Bering Straits at this time also remained dry land.
Little Ice Age (LIA), climate interval that occurred from the early 14th century through the mid-19th century, when mountain glaciers expanded at several locations, including the European Alps, New Zealand, Alaska, and the southern Andes, and mean annual temperatures across the Northern Hemisphere.
The Little Ice Age was a period of wide-spread cooling that lasted from the end of the Medieval Warm Period early in the 14th century, until the present-day warming trend that started in the middle to late 19th century (graph below).
Proxy records showed that mountain glaciers grew during the Little Ice Age at several locations—including the European Alps, New Zealand, Alaska, and the southern Andes—and mean annual temperatures across the Northern Hemisphere fell by 0.6 °C (1.1 °F) relative to the average temperature between 1000 and 2000 CE.
19 wrz 2022 · In the 2004 blockbuster “The Day After Tomorrow,” the Northern Hemisphere experiences an abrupt and catastrophic plunge into Ice Age conditions. The culprit? Extreme rates of melting ice from the poles cause a massive disruption in the ocean currents that distribute heat around the planet.
The term Little Ice Age was originally coined by F Matthes in 1939 to describe the most recent 4000 year climatic interval (the Late Holocene) associated with a particularly dramatic series of mountain glacier advances and retreats, analogous to, though considerably more moderate than, the Pleistocene glacial fluctuations.
