The climate of Iceland's coast is subarctic. The warm North Atlantic Current ensures generally higher annual temperatures than in most places of  similar latitude in the world. Regions in the world with similar  climates include the Aleutian Islands, the Alaska Peninsula, and Tierra del Fuego,  although these regions are closer to the equator. Despite its proximity  to the Arctic, the island's coasts remain ice-free through the winter.  Ice incursions are rare, the last having occurred on the north coast in 1969.

The climate varies between different parts of the island.  Generally speaking, the south coast is warmer, wetter, and windier than  the north. The Central Highlands are the coldest part of the country.  Low-lying inland areas in the north are the most arid. Snowfall in  winter is more common in the north than the south.

The highest air temperature recorded was 30.5 °C (86.9 °F) on 22  June 1939 at Teigarhorn on the southeastern coast. The lowest was −38 °C  (−36.4 °F) on 22 January 1918 at Grímsstaðir and Möðrudalur in the  northeastern hinterland. The temperature records for Reykjavík are  26.2 °C (79.2 °F) on 30 July 2008, and −24.5 °C (−12.1 °F) on 21 January  1918.

Biodiversity

Around 1,300 species of insects are known in Iceland. This is low  compared with other countries (over one million species have been  described worldwide). Iceland is essentially free of mosquitoes. The only native land mammal when humans arrived was the Arctic fox, which came to the island at the end of the ice age, walking over the  frozen sea. On rare occasions, bats have been carried to the island with  the winds, but they are not able to breed there. Polar bears occasionally come over from Greenland, but they are just visitors, and no Icelandic populations exist. No native or free-living reptiles or amphibians are on the island.

Phytogeographically, Iceland belongs to the Arctic province of the Circumboreal Region within the Boreal Kingdom.  Around three-quarters of the island is barren of vegetation; plant life  consists mainly of grassland, which is regularly grazed by livestock.  The most common tree native to Iceland is the northern birch (Betula pubescens), which formerly formed forests over much of Iceland, along with aspens (Populus tremula), rowans (Sorbus aucuparia), common junipers (Juniperus communis), and other smaller trees, mainly willows.

When the island was first settled, it was extensively forested. In the late 12th century, Ari the Wise described it in the Íslendingabók as "forested from mountain to sea shore". Permanent human settlement greatly disturbed the isolated ecosystem of thin, volcanic soils and limited species diversity. The forests were heavily exploited over the centuries for firewood and timber. Deforestation, climatic deterioration during the Little Ice Age, and overgrazing by sheep imported by settlers caused a loss of critical topsoil due to erosion.  Today, many farms have been abandoned. Three-quarters of Iceland's  100,000 square kilometres is affected by soil erosion, 18,000 km2 (6,900 sq mi) serious enough to make the land useless. Only a few small birch stands now exist in isolated reserves. The  planting of new forests has increased the number of trees, but the  result does not compare to the original forests. Some of the planted  forests include introduced species. The tallest tree in Iceland is a sitka spruce planted in 1949 in Kirkjubæjarklaustur; it was measured at 25.2 m (83 ft) in 2013.

The animals of Iceland include the Icelandic sheep, cattle, chickens, goats, the sturdy Icelandic horse, and the Icelandic Sheepdog, all descendants of animals imported by Europeans. Wild mammals include the Arctic fox, mink, mice, rats, rabbits, and reindeer.  Polar bears occasionally visit the island, travelling on icebergs from  Greenland. In June 2008, two polar bears arrived in the same month. Marine mammals include the grey seal (Halichoerus grypus) and harbor seal (Phoca vitulina). Many species of fish live in the ocean waters surrounding Iceland, and the fishing industry is a major part of Iceland's economy, accounting for roughly half of  the country's total exports. Birds, especially seabirds, are an  important part of Iceland's animal life. Puffins, skuas, and kittiwakes nest on its sea cliffs.
