Iestyn said he saw thousands of mauve stingers on a dive in the summer – a small but venomous jellyfish typically seen in the Mediterranean.<\/p>\n

“I can’t express how many there were. I had to get out because I couldn’t see, there were so many.”<\/p>\n

He described it as a “telltale sign” of climate change.<\/p>\n

Average sea temperatures around the UK and Ireland range from 6-10C (43 – 50F) in the winter to 15-20C (59 – 68F) in the summer, according to the Met Office, external<\/a>.<\/p>\n

But a marine heatwave in summer 2025 saw sea temperatures in parts of the UK up to 3C (37.4F) above normal at times.<\/p>\n

Fuelled by climate change, BBC analysis found that the world’s oceans broke temperature records every single day over the year of 2024<\/a>.<\/p>\n

“While it’s cool for me as I get to see these cool encounters as we have new species that we wouldn’t necessarily have before, it is a concern looking forward,” said Iestyn.<\/p>\n

“In my night dives I see squid all the time, obviously I haven’t been doing this for years so I can’t say just how common they were before.<\/p>\n

“But the sheer amount of squid I’ve been seeing does suggest the warm waters are having an impact.<\/p>\n

“Everybody is going to be affected… I don’t think it’s talked about enough, it’s become a normality.<\/p>\n

“I think if we can shift away from that and have discussions about how big of a problem it is, that could be really important.”<\/p>\n","protected":false},"excerpt":{"rendered":"Iestyn said he saw thousands of mauve stingers on a dive in the summer – a small but…\n","protected":false},"author":2,"featured_media":524227,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[26],"tags":[90,56,54,55,4407],"class_list":["post-524226","post","type-post","status-publish","format-standard","has-post-thumbnail","category-wildlife","tag-science","tag-uk","tag-united-kingdom","tag-unitedkingdom","tag-wildlife"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts\/524226","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/comments?post=524226"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts\/524226\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/media\/524227"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/media?parent=524226"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/categories?post=524226"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/tags?post=524226"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
