The acid test
The Arctic seas are being made rapidly more acidic by carbon dioxide emissions which could bring about major changes in the marine ecosystem, according to a new report. Scientists monitored widespread changes in ocean chemistry in the region and say even if CO2 emissions stopped now, it would take tens of thousands of years for Arctic Ocean chemistry to revert to pre-industrial levels. Many creatures, including commercially valuable fish, could be affected. It is well known that CO2 warms the planet, but less well-known that it also makes the alkaline seas more acidic when it is absorbed from the air.
