Oceans marked 365 straight days of record-breaking global surface sea temperatures this week, fuelling concerns among international scientists that climate change could push marine ecosystems beyond a tipping point.
The consistent climb in temperatures reached a peak on Wednesday when the new all-time high was set for the past 12 months, at 21.2C.
The world’s seas have yet to show any signs of dropping to typical, seasonal temperatures, with daily records consecutively broken since they first went off the charts in mid-March last year, according to data from the US National Atmospheric and Oceanic Administration and the Climate Reanalyzer research collaboration.
