Pteropods, or sea butterflies, are tiny, free-swimming marine snails which have developed two wing-like flaps in place of the large muscular foot of most snails. They beat these ‘wings’ constantly to remain near the surface of the ocean.
You may have heard the news that atmospheric concentrations of carbon dioxide have pushed past 400 parts per million at monitoring stations in the Arctic.
Carbon dioxide is a heat-trapping gas, in fact the most pervasive greenhouse gas contributing to climate change, and scientists are noting this signpost with concern as it indicates that the effects of increased CO2 and climate change – soaring pollution and temperatures, melting sea ice and glaciers, and rising sea levels – will continue unabated for the foreseeable future. What you may not have heard is what this milestone means for our oceans and marine life.
Ocean acidification is the lesser known consequence of greenhouse gas pollution. Every day we release millions of tons of CO2 into the atmosphere, and a significant portion is absorbed by our oceans. The oceans’ regulation of our climate via absorption is a natural process, but the amount of CO2 our oceans are now absorbing is unprecedented and is causing our oceans to become more acidic.
