In a short and handy format, in an all-audience language, the new听听summarizes new findings and results on the situation of ocean acidification. Are Olsen, , Siv Kari Lauvset and write:

鈥淲e are able to document the ocean CO₂听uptake and acidification because the global science community has made systematic measurements in the oceans over the past decades. The data clearly show that CO₂听levels are increasing and pH is decreasing. In particular, time series stations, where observations are made several times each year, show that in the surface ocean, CO_2听is increasing at approximately the same rate as in the atmosphere and pH follows suit.鈥�

鈥淭he total amount of anthropogenic CO₂听in the ocean can be determined from the measurements. It is now approximately 620 gigatons of CO₂, which corresponds to 27% of the total emissions from 1800 to 2016鈥�

The听Foresight brief听summarises important findings and results on observations of ocean carbon uptake and acidification, future projections, ecosystem impacts and possible consequences for marine food resources, and is based on research at the and from the research community at large.

鈥� It is both an overview and an introduction to the theme of ocean acidification at large. We are not only presenting our own activities, but are also giving an overview of various other sides of the ocean acidification problem, like effects and impact that are studied at other research communities, Ingunn Skjelvan, researcher at 听and the , says.听

鈥� We are happy to contribute to such an overview that is also spread in the UN system, Are Olsen, professor at the Geophysical Institute and , adds.
