Ever heard about “phantom recoveries” and “overfishing ratchets” ? These explain why still so many fish stocks are in a bad shape in European waters despite binding goals of the EU fisheries policy. www.science.org/doi/10.1126/...
Systemic failure of European fisheries management
Overcoming shortsighted interests with politically independent ecosystem-based catch limits may end overfishing in EU waters

We often focus on global surface temperatures as a key metric for climate change.
But as we note in the Climate Trends chapter of the new US 5th National Climate Assessment, we see incontrovertible evidence for climate change across the oceans, land, cryosphere, and atmosphere:
