Climate change impacts in the marine environment

点击翻译按钮获取中文摘要

Global climate change is having two important effects on the world's oceans: 1), sea surface temperature is increasing due to the greenhouse effect, and 2) the acidity of the oceans is increasing due to excess carbon dioxide. These two changes will have far-reaching consequences for marine species, many of which are ecologically, economically, and culturally valuable in Canada. For example, rising temperatures are causing species ranges to shift to higher latitudes and deeper waters, and rising acidity is beginning to limit growth rates in species that build shells or skeletons out of calcium carbonate (e.g. corals and molluscs).
