<onlyinclude>The '''Little Ice Age (LIA)''' is the name given to a brief [[Glacial and interglacial periods|glaciation period]] that occurred between the 1300s and the mid 1800s. [[Temperature|Temperatures]] dropped an average of 1°C which resulted in significant global glacier advancement.</onlyinclude><ref>S. G. Philander, Ed., Encyclopedia of global warming and climate change, vol. 2, 3 vols. Los Angeles: SAGE, 2008. pp. 522.</ref> The frigid temperatures sent all of Europe, most of North America, the Andes and New Zealand into an [[ice age]].<ref name="ref1"/>

===Causes===

There is evidence that multiple causes may have resulted in the LIA. The most probable theory is a decrease in solar activity, which is directly related to a decrease in the number of sunspots during this time. As a result, the [[Earth]] was receiving less energy from the sun thus lowering temperatures. There were three major decreases in solar activity between 1400 and 1900 known as the [[Spörer Minimum]] (1450-1550), the [[Maunder Minimum]] (1645-1715) and the [[Dalton Minimum]] (1790-1830).<ref name="ref2"/> Another theory that may have led to the LIA was an increase in [[External forcing|volcanic activity]]. Volcanic activity such as eruptions release massive amounts of [[Aerosol|aerosols]] into the [[Atmosphere|atmosphere]] which, once suspended in the atmosphere for a long period of time, reflect sunlight and ultimately cool Earth’s surface.<ref>B. Allen, “Atmospheric Aerosols: What Are They, and Why Are They So Important?,” NASA, 06-Apr-2015. [Online]. Available: http://www.nasa.gov/centers/langley/news/factsheets/Aerosols.html. [Accessed: 09-Feb-2018].</ref> These factors are an example of [[Natural vs anthropogenic climate change|natural climate change]]. However, earth is still in the natural warming process from this glacial advance and many [[climate change denier]]s erroneously claim that this is the cause for the current dramatic climate changes. Although natural climate factors have some effect on the current global warming, they are not as drowned out by the human induced factors.

Here is a video from the Denial 101x series explaining the Little Ice Age:
