Ocean-based mitigation and negative emission technologies and practices

The latest IPCC report on Ocean and Cryosphere in a Changing Climate, which builds upon previous IPCC’s reports, established a causal link between anthropogenic impacts and ocean acidification, by noting a significant decrease in the Ocean’s uptake of CO2, with consequent damage to Earth’s ecosystems, which in turn has traceable repercussions on the Arctic Ocean and then from the Arctic to the Planet Earth.

Arctic sea ice decline in recent decades is one of the most visible indicators of global warming. The sea-ice albedo feedback is an essential impact of sea ice melt, which amplifies Arctic temperature change. In this study, an optimal path for fossil fuel and industrial CO2 emission reduction is sought. Devoting more resources to mitigation implies a decrease in consumption and investment, implying a loss in net welfare.
