What is the tundra biome?<\/strong><\/h3>\n<p>The tundra is a biome characterised by cold temperatures, short growing seasons, and little to no trees. The tundra biome covers about 10% of Earth&#8217;s surface. There are three types of tundra: Arctic tundra, alpine tundra, and Antarctic tundra.<\/p>\n<h3><strong>Q.2. What is the significance of the Albedo effect?<\/strong><\/h3>\n<p>The albedo effect is a key concept in climate science that explains how the Earth&#8217;s surface reflects sunlight and how this affects the planet&#8217;s temperature. It&#8217;s important because it helps scientists calculate the Earth&#8217;s energy budget and predict climate change.<\/p>\n<p><strong>Source:<\/strong> <a href=\"https:\/\/indianexpress.com\/article\/explained\/explained-climate\/as-green-patch-spreads-in-antarctica-heres-what-is-worrying-scientists-9614478\/\" target=\"_blank\" rel=\"nofollow noopener\">As green patch spreads in Antarctica, here\u2019s what is worrying scientists<\/a> | <a href=\"https:\/\/www.downtoearth.org.in\/climate-change\/antarctic-peninsula-showed-10-fold-greening-since-1986-with-increased-warming-study\" target=\"_blank\" rel=\"nofollow noopener\">DTE<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Due to climate change, plant cover in the Antarctic peninsula area has increased dramatically over the past few decades, raising concerns about the future of this unique ecosystem<\/p>\n","protected":false},"author":5,"featured_media":42901,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[18],"tags":[],"class_list":{"0":"post-42900","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-upsc-mains-current-affairs","8":"no-featured-image-padding"},"acf":[],"_links":{"self":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/posts\/42900","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/users\/5"}],"replies":[{"embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/comments?post=42900"}],"version-history":[{"count":0,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/posts\/42900\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/media\/42901"}],"wp:attachment":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/media?parent=42900"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/categories?post=42900"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/tags?post=42900"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
