CO2 is at its highest concentration in at least 650,000 years. Temperatures, rainfall and sea level rise are getting attention, but there's another big consequence: the increasing acidification of the sea. The oceans have taken up about half of the CO2 we have produced in the last 200 years, making them more acidic. As the oceans become more acidic organisms which make their shells and skeletons from calcium carbonate have increasing difficulty in doing so. Acidification of the sea also alters the availability of nutrients for phytoplankton and bacteria. Marine environment communities will change as a direct effect of acidification as well as from resulting changes in food webs. Predicting these changes, as well as the environmental and economic consequences of these changes is a major challenge in marine biology.</p>
