The study, led by Kara Lamantia from The Ohio State University&#8217;s Byrd Polar and Research Climate Center, reveals that El Ni\u00f1o has drastically reduced the QIC&#8217;s snow-covered area over the past four decades.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">&#8220;Our research gives us a look into a glacier\u2019s health,&#8221; Lamantia said in a <a href=\"https:\/\/news.osu.edu\/researchers-link-el-nino-to-accelerated-ice-loss-in-tropics\/\">news release<\/a>. &#8220;The Quelccaya glacier becomes greatly out of equilibrium during these short-term climate anomalies.&#8221;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/tc.copernicus.org\/articles\/18\/4633\/2024\/\" title=\"\">Published <\/a>in The Cryosphere journal, the study is the first to automate the detection of snow-covered areas on the QIC. Using NASA Landsat satellite images and a newly developed algorithm that processes near-infrared imagery, the researchers confirmed that El Ni\u00f1o significantly accelerates ice loss. From 1985 to 2022, the QIC lost 58% of its snow cover and 37% of its total area.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">&#8220;By creating a threshold for the different reflectance between snow and ice cover, we can gather a consistent and much more reliable measurement,&#8221; Lamantia added.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">El Ni\u00f1o induces warmer and drier conditions in southern Peru, depleting snow cover during the typically wet season. As a result, the glacier&#8217;s snow cover continues to decline without sufficient snowfall to replenish it. This trend has dire implications, especially as climate change is expected to intensify and prolong El Ni\u00f1o events.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">&#8220;The ice cap as a whole is on a very consistent linear decline from anthropogenic warming,&#8221; added Lamantia. &#8220;It may not matter how strong future La Ni\u00f1as are, as the freezing line continues to rise and snow cover shrinks, Quelccaya will likely continue to decline.&#8221;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The potential disappearance of the QIC by 2080 could mirror the fate of Kilimanjaro&#8217;s glaciers, severely impacting local communities reliant on glacial meltwater. The study highlights the urgent need for innovative water conservation strategies in face of escalating climate change.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">&#8220;The general consensus is we can expect that the likely increased intensity and duration of El Ni\u00f1os will cause more complications for the QIC,&#8221; said Lamantia. &#8220;We need to start being clever about how we use and conserve our water resources.&#8221;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The study&#8217;s co-authors include Lonnie Thompson and Bryan Mark from Ohio State and Laura J.
