A cold period that lasted from about A.D. 1550 to about A.D. 1850. This was the coldest period in about 1,500 years. There are many records - both scientific and historic that substantiate this.

This period was marked by rapid expansion of mountain [[glacier]]s, especially in the Alps, Norway, Ireland, and Alaska. There were three maxima, beginning about 1650, about 1770, and 1850, each separated by slight [[warming trend]].<ref> [http://earthobservatory.nasa.gov/Library/glossary.php3?mode=all NASA Earth Observatory glossary] </ref>

An attempt was made by the UN's global warming study panel to dismiss the existence of the Little Ice Age, using the notorious [[hockey stick graph]] of Dr. [[Michael Mann]].
