'The Darkening Sea'


When considering the effects of climate change on the Earth’s oceans, most attention is given to rising sea levels and temperatures. However, a recent article in The New Yorker, ‘The Darkening Sea’, provides a fascinating and thoughtful explanation of another dire consequence of global warming. The article describes the efforts of scientists to understand and model the process of ocean acidification. More specifically, the article suggests that since the start of the 19th century, the sea has absorbed roughly have of the world’s carbon dioxide emissions. Subsequently, it is believed that increased levels of carbon dioxide in the atmosphere have led to and will continue to lead to a change in the oceans’ chemistry. This process, which is characterized by a decline in pH levels, is currently threatening the survival of an estimated one million aquatic species. Yet, another reason to demand immediate action on climate change. See also ::Mr. Pico Dissolves
