* Sea level rise<ref>Sea level rise: 2m rise expected by the year 2100, 6.5m by 2200</ref> will contaminate a very large percentage of the planets' agricultural fields with sea salt and make them no longer suitable for continued food production.<ref>Earth under water documentary</ref> In addition, many low-lying islands and coastlines will need to be abandoned, forcing many people to move.
* Increasing ocean acidity. As the pH of water decreases due to the input of carbonic acid (resulting from CO2 dissolving in water), life forms which rely on a chalk shell will find it increasingly impossible to survive. This will have negative effects on many ocean ecosystems, especially coral reefs which are the most bio-diverse of any ecosystem on the planet.
