A demise that will cause global humanitarian crises, if not halted:\u00a0 70 percent of fresh water on Earth is locked up in glaciers. As glaciers melt, due to normal seasonal variations, they supply water to millions of people in the high mountains. But this source will slowly diminish as glaciers shrink irrevocably due to global warming, says Wadham.<\/p>\n<p>Mountain glaciers and the Greenland and Antarctic Ice Sheets are melting at accelerating rates and in some cases exceeding what most alarming predictions could foresee. But this will have impacts beyond rising sea levels, involving shifts in ocean food webs, fisheries, and potentially the release of the potent greenhouse gas methane from the guts of ice sheets, all with impacts on Earth\u2019s carbon cycle.<\/p>\n<p>Jemma Wadham is one of the world&#8217;s foremost experts in glaciology, the scientific study of everything ice. She has spent 25 years researching the majestic but dwindling ice covers &#8211; from glaciers in fiords of Svalbard archipelago in Arctic Norway, to Antarctic giants.<\/p>\n<h2>An urgency brought upon by illness<\/h2>\n<p>Many high profile scientific publications resulted from this dangerous labour, informing the scientific community of the state of the natural world facing global warming.<\/p>\n<figure id=\"attachment_6172\" aria-describedby=\"caption-attachment-6172\" style=\"width: 1200px\" class=\"wp-caption aligncenter\"><img decoding=\"async\" class=\"wp-image-6172 size-default-lg lazyload\" data-src=\"https:\/\/site.uit.no\/cage\/wp-content\/uploads\/2021\/05\/jemma-wadham-joyce-glacier-antarctica-j-wadham-1200x700.jpg\" alt=\"\" width=\"1200\" height=\"700\" data-srcset=\"https:\/\/site.uit.no\/cage\/wp-content\/uploads\/sites\/492\/2021\/05\/jemma-wadham-joyce-glacier-antarctica-j-wadham-1200x700.jpg 1200w, https:\/\/site.uit.no\/cage\/wp-content\/uploads\/sites\/492\/2021\/05\/jemma-wadham-joyce-glacier-antarctica-j-wadham-600x350.jpg 600w\" data-sizes=\"(max-width: 1200px) 100vw, 1200px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 1200px; --smush-placeholder-aspect-ratio: 1200\/700;\" \/><figcaption id=\"caption-attachment-6172\" class=\"wp-caption-text\">Professor Wadham has done fieldwork on many of the major glaciers and ice sheets in the world &#8211; From the High Arctic to Antarctica.

Emergency surgery revealed a benign cyst, the size of a tangerine, which was removed from her head. Even though the growth was non-cancerous, it was life-threatening. When faced with their mortality, people often adjust and focus on their perspectives.<\/p>\n<p>Jemma Wadham\u2019s focus turned to communicate cutting edge science to the public with a deeply felt personal hope that it would inform good decisions to be made for our planet\u2019s future.<\/p>\n<blockquote><p><strong>\u201cEvery fraction of degree which we manage to<em> not warm<\/em> the atmosphere can make a difference for our glaciers and the benefits they provide to us,\u201d she says.<\/strong><\/p><\/blockquote>\n<p>Wadham decided to write a book of memoirs. <a href=\"https:\/\/www.penguin.co.uk\/books\/319535\/ice-rivers\/9780241467688.html\">Ice Rivers, a personal and passionate recollection of her own life and relationship with glaciers, released by Penguin on May 6th<\/a>. The manuscript took only seven weeks to draft and is both an inspiring, humorous, and ambitious book.<\/p>\n<h2>&#8220;I was fascinated by ice&#8221;<\/h2>\n<p>About her decision to do her PhD on Svalbard, Wadham writes: \u201cI remember some family members being rather suspicious when I announced that I would be embarking on a three-year doctorate on glaciers: \u2018Why on Earth would you want to be stuck in the freezing Arctic on top of a block of ice? You hate the cold!\u2019 (Fair\u00a0\u00a0 point \u2013 I do.) \u2018And is that really a fitting career path for a woman, among all those men?\u2019 Yet to become a glaciologist was almost an instinctive choice to me \u2013 I loved the wilderness and freely roaming mountains, I was fascinated by ice, and my ambitions to date had been to become a farmer, an agricultural mechanic or a forest ranger \u2013 none of which had gone down very well. My school had refused me work experience in the sixth form because they didn\u2019t regard farming as a respectable career for a girl; while other pupils swanned off to swanky offices in London, I\u2019d simply stayed at home, a misfit with limited prospects. When the University of Bristol offered me a PhD place to study glaciers in the High Arctic, I was elated \u2013 maybe there was hope for me after all.\u201d<\/p>\n<figure id=\"attachment_6174\" aria-describedby=\"caption-attachment-6174\" style=\"width: 1024px\" class=\"wp-caption aligncenter\"><img decoding=\"async\" class=\"wp-image-6174 size-large lazyload\" data-src=\"https:\/\/site.uit.no\/cage\/wp-content\/uploads\/2021\/05\/finsterwalderbeeen-jemma-wadham-1024x663.jpg\" alt=\"\" width=\"1024\" height=\"663\" data-srcset=\"https:\/\/site.uit.no\/cage\/wp-content\/uploads\/sites\/492\/2021\/05\/finsterwalderbeeen-jemma-wadham-1024x663.jpg 1024w, https:\/\/site.uit.no\/cage\/wp-content\/uploads\/sites\/492\/2021\/05\/finsterwalderbeeen-jemma-wadham-300x194.jpg 300w, https:\/\/site.uit.no\/cage\/wp-content\/uploads\/sites\/492\/2021\/05\/finsterwalderbeeen-jemma-wadham-768x497.jpg 768w, https:\/\/site.uit.no\/cage\/wp-content\/uploads\/sites\/492\/2021\/05\/finsterwalderbeeen-jemma-wadham-1536x994.jpg 1536w, https:\/\/site.uit.no\/cage\/wp-content\/uploads\/sites\/492\/2021\/05\/finsterwalderbeeen-jemma-wadham-scaled.jpg 2048w, https:\/\/site.uit.no\/cage\/wp-content\/uploads\/sites\/492\/2021\/05\/finsterwalderbeeen-jemma-wadham-1920x1242.jpg 1920w\" data-sizes=\"(max-width: 1024px) 100vw, 1024px\" src=\"data:image\/svg+xml;base64,PHN2ZyB3aWR0aD0iMSIgaGVpZ2h0PSIxIiB4bWxucz0iaHR0cDovL3d3dy53My5vcmcvMjAwMC9zdmciPjwvc3ZnPg==\" style=\"--smush-placeholder-width: 1024px; --smush-placeholder-aspect-ratio: 1024\/663;\" \/><figcaption id=\"caption-attachment-6174\" class=\"wp-caption-text\">Finsterwalderbreen is a glacier on Svalbard and the site of Professor Wadham&#8217;s PhD studies, where she spent many months doing fieldwork trying to figure out what was really happening beneath the enormous expanse of ice.
