The study of this correlation is called\u00a0stratigraphy.<\/li>\n<\/ul>\n<\/li>\n<li>Current Epoch: Officially, the current epoch is called the\u00a0Holocene, which\u00a0began 11,700 years ago after the last major ice age.\u00a0<\/li>\n<li>Debate:\n<ul>\n<li>Scientists still debate\u00a0whether the Anthropocene is different from the Holocene.<\/li>\n<li>The term\u00a0Anthropocene has not been formally adopted by the International Union of Geological Sciences\u00a0(IUGS),\u00a0the international organization that names and defines epochs.\u00a0<\/li>\n<li>The\u00a0primary question that the IUGS needs to answer before declaring the Anthropocene an epoch\u00a0is if humans have changed the Earth system\u00a0to the point that it is reflected in the rock strata.<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<hr \/>\n<h3>Q1) What is the International Union of Geological Sciences (IUGS)?<\/h3>\n<p>The International Union of Geological Sciences (IUGS), founded in 1961, is one of the World\u2019s largest scientific organizations. It encourages international cooperation and participation in the earth sciences in relation to human welfare and is a member of the International Council for Science (ICSU). Membership is open to countries or defined regions. IUGS has over 120 members representing over a million geoscientists.<\/p>\n<p><strong>Source:<\/strong> <a href=\"https:\/\/edition.cnn.com\/2024\/03\/05\/world\/anthropocene-epoch-rejected-scn\/index.html\" target=\"_blank\" rel=\"nofollow noopener\"><u>Proposal to mark a new chapter in Earth\u2019s history rejected, scientists say<\/u><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Anthropocene Epoch is used to describe the most recent period in Earth\u2019s history when human activity started to have a significant impact on the planet\u2019s climate and ecosystems. <\/p>\n","protected":false},"author":5,"featured_media":21436,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[1],"tags":[],"class_list":{"0":"post-21435","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\/21435","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=21435"}],"version-history":[{"count":0,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/posts\/21435\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/media\/21436"}],"wp:attachment":[{"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/media?parent=21435"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/categories?post=21435"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/vajiramandravi.com\/current-affairs\/wp-json\/wp\/v2\/tags?post=21435"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
