Crabs, for example, live in a crusty shell built from the calcium carbonate prevalent in ocean water.\u00a0<\/li>\n<li>Seawater is normally alkaline, with a pH value of around 8.1.<\/li>\n<li>The researchers point to sea-ice melt as the key mechanism to explain this rapid pH decrease, because it changes surface water in three primary ways.\n<ul>\n<li>First, the water under the sea ice, which had a deficit of carbon dioxide, now is exposed to the atmospheric carbon dioxide and can take it up freely.<\/li>\n<li>The seawater mixed with meltwater is light and can\u2019t mix easily into deeper waters, which means the carbon dioxide is concentrated at the surface.<\/li>\n<li>The meltwater dilutes the carbonate ion concentration in the seawater, weakening its ability to neutralise the carbon dioxide into bicarbonate and rapidly decreasing ocean pH.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<p>&nbsp;<\/p>\n<hr \/>\n<p><strong>Source :\u00a0<\/strong><a href=\"https:\/\/indianexpress.com\/article\/explained\/explained-climate\/arctic-ice-melting-climate-change-8186502\/\" target=\"_blank\" rel=\"nofollow noopener\">Indian Express<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Arctic sea ice reaches its minimum extent each September.Sea ice extent is one of three key sea ice metrics<\/p>\n","protected":false},"author":5,"featured_media":8909,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[1],"tags":[],"class_list":{"0":"post-8908","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-upsc-prelims-current-affairs","8":"no-featured-image-padding"},"acf":[],"_links":{"self":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/posts\/8908","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=8908"}],"version-history":[{"count":0,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/posts\/8908\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/media\/8909"}],"wp:attachment":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/media?parent=8908"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/categories?post=8908"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/tags?post=8908"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
