The summit offered some signs of progress in the race to save our oceans with more nations ratifying a global treaty to protect 30% of the high seas by 2030, Jamaica, Indonesia and Norway among them. It means that 50 nations have now ratified the treaty – just shy of the 60 needed to make it law. Calls to halt deep-sea mining also gained momentum in Nice, with 37 countries supporting a precautionary pause or outright ban. Tom Pickerell of the World Resources Institute said it was “a hopeful sign of political will to protect fragile ecosystems”. “There’s real momentum coming out of Nice but also a lot of unfinished business,” he added.
