Ocean acidification can now be seen from space, highlighting an ongoing danger of climate change and revealing the regions most at risk.
Seawater absorbs about a quarter of the carbon dioxide, a greenhouse gas, that humans release into the atmosphere each year, mostly from the burning of fossil fuels, according to the National Oceanic and Atmospheric Administration (NOAA).
