There are two types of polar climate: '''ET''', or [[tundra climate]]; and '''EF''', or [[ice cap climate]]. A tundra climate is characterized by having at least one month whose average temperature is above {{convert|0|C|F}}, while an ice cap climate has no months averaging above {{convert|0|C|F}}.<ref>{{cite book | last1=McKnight | first1=Tom L | last2=Hess | first2=Darrel | year=2000 | chapter=Climate Zones and Types: The Köppen System | title=Physical Geography: A Landscape Appreciation | pages=[https://archive.org/details/physicalgeographmckn/page/235 235–7] | location=Upper Saddle River, NJ | publisher=Prentice Hall | isbn=978-0-13-020263-5 | chapter-url-access=registration | chapter-url=https://archive.org/details/physicalgeographmckn | url=https://archive.org/details/physicalgeographmckn/page/235 }}</ref> In a tundra climate, even [[coniferous]] trees cannot grow, but other specialized plants such as the arctic poppy can grow. In an ice cap climate, no plants can grow, and ice gradually accumulates until it flows or slides elsewhere. Many [[high altitude]] locations on Earth have a climate where no month has an average temperature of {{convert|10|C|F}} or higher, but as this is due to elevation, this climate is referred to as [[Alpine climate]]. Alpine climate can mimic either tundra or ice cap climate.
