• 17th-century Europe ( in Europe, history of: Climate )

  Given man’s dependence on nature, the deterioration of the climate during the Little Ice Age of the 17th century should be considered as a demographic factor. The absence of sunspots after 1645 was noted by astronomers using the recently invented telescope; the aurora borealis (caused by high-energy particles from the Sun entering the Earth’s atmosphere) was so rarely visible that it was...

• centennial-scale climate variation ( in climate change: Centennial-scale variation )

  ...has changed during the past 1,000 years at centennial timescales; that is, no two centuries have been exactly alike. During the past 150 years, the Earth system has emerged from a period called the Little Ice Age, which was characterized in the North Atlantic region and elsewhere by relatively cool temperatures. The 20th century in particular saw a substantial pattern of warming in many...

• ice age ( in ice age )

  A lesser, recent glacial stage called the Little Ice Age began in the 16th century and advanced and receded intermittently over three centuries in Europe and many other regions. Its maximum development was reached about 1750, at which time glaciers were more widespread on Earth than at any time since the last major ice age ended about 11,500 years ago.

• Mendenhall Glacier ( in Mendenhall Glacier )

  ...more than 100 feet (30 metres) high at its terminus. It flows from the southern half of the huge Juneau Icefield, which begins in the Boundary Ranges along the Alaska-Canada border. A relic of the Little Ice Age that lasted until the mid-18th century, the Mendenhall Glacier is an example of a receding glacier (about 100 to 150 feet [30 to 45 metres] a year), displaying raw glacier moraine with...

• oceans ( in ocean: El Niño/Southern Oscillation and climatic change )

  ...20,000 to 40,000 years, interrupted by interglacial periods of “optimum” climate, such as the present. The climatic modulations that occur at shorter scales include such periods as the Little Ice Age from the early 16th to the mid-19th centuries, when the global average temperature was approximately 1° C lower than it is today. Several climate fluctuations on the scale of...

• Sub-Atlantic Climatic Interval ( in Holocene Epoch: Little Ice Age )

  Throughout most of what is commonly called the Little Ice Age (1500–1850) the mean solar activity was quite low, but positive fluctuations occurred around 1540–90 and 1770–1800. The main westerly storm belts shifted about 500 kilometres to the south, and for much of the time the northern latitudes came under cool continental conditions. Observed temperature series in Europe...
