The Intergovernmental Panel on Climate Change (IPCC) has today (9 August 2021) released its next report; the Working Group I contribution to the Sixth Assessment Report (AR6).

New generation of micro sensors for monitoring ocean acidification

The burning of fossil fuels is releasing vast quantities of extra carbon dioxide (CO2) to the Earth’s atmosphere. While a proportion of this stays in the atmosphere, raising atmospheric CO2 levels, around half is removed over time, either to become sequestered in trees and plants or to become absorbed in the ocean.
