Little Ice Age-Sep 17

The Little Ice Age was a period of regionally cold conditions between roughly AD 1300 and 1850. 

There were two phases of the Little Ice Age, the first beginning around 1290 and continuing until the late 1400s. There was a slightly warmer period in the 1500s, after which the climate deteriorated substantially, with the coldest period between 1645 and 1715. 

During this coldest phase of the Little Ice Age, there are indications that average winter temperatures in Europe and North America were as much as 2°C lower than present-day.
