Top ocean researchers release first major ocean-acidification report and brief Congress, highlighting marine changes they fear are possible by century’s end. In the past two centuries, the oceans have absorbed one-third of CO2 emissions, altering ocean chemistry, reducing seawater pH, and affecting marine animals and phytoplankton in multiple ways. Ocean acidification changes the coasts, releasing excess nutrient that can create algae blooms and increasing sea temperatures and salinity, according to NOAA. The Pacific Partnership on Ocean Acidification will focus on: 1. 2007 Feely and colleagues take an ocean research trip between Canada and Mexico and find enormous stretches of seawater already changing in ways not expected for 50 to 100 years . The study authors looked at ocean acidification levels from 2016. HOW ISSUE LINKS TO/IMPACTS SDGs BEYOND SDG14 LIFE BELOW WATER SDG2: sustainable management of our marine resources is vital for food security in the Pacific.
