The authors are calling for better monitoring of tropical lakes, which are home to countless endangered species and are particularly vulnerable to climate change.<\/p>\n

A prolonged drought and heat wave in September 2023 turned lakes in Brazil\u2019s Amazonas state into \u201cshallow simmering basins\u201d with water temperatures above 40\u00baC \u2014 hot enough to kill more than 200 endangered river dolphins, along with thousands of fish and other aquatic species.<\/p>\n

“You couldn’t put your finger in the water,” Ayan Fleischmann, the study\u2019s lead author and a hydrologist at western Brazil’s Mamiraua Institute for Sustainable Development, told AFP<\/a>.<\/p>\n

The authors say the event highlights a \u201cworrisome warning trend\u201d across rivers and lake basins, especially for those in the Amazon, which are poorly monitored and understudied.<\/p>\n

Intense water temperatures<\/p>\n

The findings are detailed in a paper<\/a> published last week in the journal Science.<\/p>\n

For their study, Fleischmann and colleagues analyzed temperatures from 10 central Amazonian lakes during the September 2023 and an October 2024 drought, supported by satellite data and computer models. They found that 5 of the lakes experienced \u201cexceptionally high\u201d daytime temperatures exceeding 37\u00baC. In the shallow waters of Lake Tef\u00e9, temperatures climbed to 41\u00baC.<\/p>\n

In 2024, Lake Tef\u00e9 lost 75 per cent of its area<\/a>, and Badaj\u00f3s Lake decreased by 90 per cent.<\/p>\n","protected":false},"excerpt":{"rendered":"Published on Nov. 12, 2025, 3:47 PM The authors are calling for better monitoring of tropical lakes, which…\n","protected":false},"author":2,"featured_media":278814,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[22],"tags":[49,48,295,66],"class_list":["post-278813","post","type-post","status-publish","format-standard","has-post-thumbnail","category-environment","tag-ca","tag-canada","tag-environment","tag-science"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts\/278813","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/comments?post=278813"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts\/278813\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/media\/278814"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/media?parent=278813"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/categories?post=278813"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/tags?post=278813"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
