Intergovernmental Panel on Climate Change last week released its newest report: The Ocean and Cryosphere in a Changing Climate. The new report lays out in stark terms the damage that climate change has already done to the planet’s oceans and vulnerable ice sheets and the potential future for these critical parts of the climate system. “The ocean has been acting like a sponge, absorbing heat and carbon dioxide to regulate global temperatures, but it can’t keep up,” IPCC vice chair Ko Barrett said. “The consequences for nature and humanity are sweeping and severe… The rapid changes are forcing people from coastal cities to remote Arctic communities to fundamentally alter their ways of life.”.
