What Climate Change Means for Florida
www.epa.govIncreasing ocean acidity can also damage corals, as well as fish . and other marine species. Ocean acidity has increased by about 25 percent in the past three centuries, and it is likely to increase another 40 to 50 percent by 2100. As the ocean becomes more acidic, corals are less able to remove minerals from the water to buildir the skeletons.
Climate Change Impacts on Marine Ecosystems
oceans.mit.eduThe primary direct consequences are increasing ocean temperatures (Bindoff et al. 2007) and acidity (Doney et al. 2009). Climbing temperatures create a host of additional changes, such as rising sea level, increased ocean stratification, decreased sea-ice extent, and altered patterns of ocean circulation, precipitation, and freshwater input

Evidence indicates that sound can travel further in the increasingly acidic ocean, resulting in a louder environment that could confuse marine mammals3. III. Additional Web Resources 1.

CHAPTER 5 PROCESSING AND SAFETY - USDA ARS
www.ars.usda.gov5.3.4 pH and Acidity Most bacteria are rapidly killed at pH and acid concentrations typical of acidified foods, but the type and concentration of acid present can play a significant role. Not all acids are equally effective in killing bacteria. The killing effects of a given type of acid can be differentiated from pH effects.
