Great white sharks are overheating

Imagine standing on a boat as a massive great white cruises nearby, and suddenly you realize — these predators are heating up too much. Johnny Sturgeon from Inside Climate News highlights that for millions of years, great whites' ability to stay warmer than the surrounding water gave them an edge. But now, with oceans warming due to climate change, they're hitting a dangerous snag — overheating. According to a new report in Science, these sharks — along with other mesothermic species like large tuna — must burn more energy just to keep their body temperature stable. That’s a double whammy, because they’re also facing declining food supplies from overfishing. So what does this mean? They’ll likely have to migrate to cooler waters, disrupting ecosystems and their survival. As Johnny Sturgeon points out, this isn’t just about individual sharks — it's a sign that climate change is rapidly reshaping marine life in ways that could be irreversible. That shift is subtle now, but it’s exactly the kind of signal that might define the next chapter for our oceans.
