Organic matter (like sphagnum moss) accumulates as peat and humus, forming a significant carbon sink.<\/li>\n<li><strong>Climate<\/strong>:\n<ul>\n<li>Temperatures<em> range from 15.5\u00b0C in summer to -60\u00b0C in winter<\/em>, with mean temperatures below 0\u00b0C for 6\u201310 months.<\/li>\n<li>Low annual precipitation (150\u2013250 mm) but minimal evaporation.<\/li>\n<li>Features 24-hour sunlight in summer and 24-hour darkness in winter.<\/li>\n<\/ul>\n<\/li>\n<li><strong>Natural Vegetation<\/strong>: Herbaceous plants like <em>grasses, mosses (e.g., reindeer moss), lichens, and liverworts dominate<\/em>.<\/li>\n<li><strong>Animal Life:<\/strong>\n<ul>\n<li><strong>Large mammals<\/strong>: Polar bears, caribou, musk oxen, and Arctic foxes.<\/li>\n<li><strong>Smaller animals<\/strong>: Lemmings and Arctic hares, which change fur color with the seasons.<\/li>\n<li><strong>Migratory birds<\/strong>, like snow geese and loons, use the tundra for breeding during summer.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<h2>Reasons for Arctic Emitting Greenhouse Gases<\/h2>\n<ul>\n<li><strong>Thawing Permafrost<\/strong>:\n<ul>\n<li>Rising global temperatures are causing permafrost to thaw.<\/li>\n<li>When the frozen soil thaws, microbes become active, breaking down the trapped organic matter, releasing carbon dioxide (CO\u2082) and methane (CH\u2084).<\/li>\n<li>Methane is especially concerning because it is a more potent greenhouse gas than CO\u2082.<\/li>\n<\/ul>\n<\/li>\n<li><strong>Wildfires<\/strong>:\n<ul>\n<li>As temperatures rise, wildfires in Arctic regions are becoming more frequent.<\/li>\n<li>Fires release large amounts of carbon stored in the vegetation and soil, further accelerating global warming.<\/li>\n<\/ul>\n<\/li>\n<li><strong>Arctic Warming Trends:<\/strong>\n<ul>\n<li>The Arctic is heating up four times faster than the global average, causing rapid changes in the biome.<\/li>\n<li>Melting ice and warming soils are significant contributors to greenhouse gas emissions.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>News: The Arctic Tundra has shifted from being a carbon sink to a carbon emitter, as confirmed by a recent analysis in the National Oceanic and Atmospheric Administration&#8217;s (NOAA) Arctic Report Card.
