The ocean has been playing an important role in helping slow down global climate change by removing greenhouse gas carbon dioxide (CO2) from the atmosphere. However, decades of ocean observations now show that the CO2 absorbed by the ocean is changing the chemistry of seawater, a process known as ocean acidification. A new study by NCEI and partners may lead to more solutions to reduce CO2 emissions and help ocean acidification adaptation strategies in regional areas.Learn more: https://go.usa.gov/xpGvY
