1. Ice sheets are active participants in the earth’s carbon cycle. Among their contributions are releasing nutrients which sequester carbon in the oceans, and producing methane hydrates which threaten to be released to the atmosphere as the ice sheets thin. https://phys.org/news/2019-08-ice-sheets-impact-core-elements.html

A 2018 article in GreenBiz discusses ways to render cement carbon negative through carbon capture and sequestration. The process could be applied to the new concrete above. Since cement is responsible for over 5% of carbon emissions the energy transition must include an effective emissions control program for it. https://www.greenbiz.com/article/concrete-change-making-cement-carbon-negative

Cement is one of the world’s most-used building materials, with production reaching 4.3 billion tons/year in 2014 and growing 5 percent to 6 percent annually.Today, it is responsible for 5.6 percent of global carbon dioxide (CO2) emissions and a major contributor to climate change — if the cement industry were a country, it would be the world’s third-largest emitter.
