最新研究称，现代社会排放的二氧化碳不仅是全球气候变暖的主要原因，更是增加了海洋的酸性，进而威胁海洋生命。科学家研究了酸化海洋对不同生命阶段的海洋生物的影响以及其对海洋食物链的影响。请听报道。
CO2 emissions are warming the planet. They're also being soaked up by the oceans, and because CO2 is mildly acidic, that's turning sea water more acidic. Since the beginning of the industrial revolution, ocean acidity has increased by around a quarter.
This huge study concludes that some organisms may benefit from this change, but others will be harmed, and all life in the sea will be affected by the resulting shifts in the food web.
Baby cod appear highly sensitive to the changing ocean chemistry expected this century. The report projects that the number of cod growing to maturity will shrink to just a quarter of the current level.
The German-based research programme also indicates that changes brought about byacidification will be made worse by climate change pollution and coastal development.
