When carbon dioxide is absorbed by the ocean, the water's acid level rises. If this level gets too high, some sea creatures that build protective shells can't grow as fast or even have their shells dissolve, threatening the entire food chain.
Significant warming is imminent and inevitable at current level of greenhouse gas carbon dioxide concentration (400 parts per million), if it rises to 800 ppm, North America could rise 8 degrees Fahrenheit warmer (on average) with major consequences.
