What’s driving the decline? The crisis isn’t just fishing — it’s invisible fishing. Much shark & ray catch is under-reported, aggregated, or mislabeled, masking real mortality & delaying management. What we don’t measure, we don’t manage.

It looks like 2025 will end up at about 1.47°C above the 1850-1900 pre-industrial baseline, making it likely the third hottest year in the last 120,000+ years. Meanwhile, the 3-year running average is going to end the year above 1.50°C for the first time.
