This is the world’s first ocean carbon-removing machine
Cutting greenhouse gas emissions at the source should be the main goal when tackling climate change, but the most recent IPCC report also recommends carbon capture and storage technologies as key parts of the effort to limit global warming to 1.5°C. The startup Heimdal is well aware of the need Read More...
Wetlands, the super carbon sink, and rewilding the Illinois River
After forests, wetlands are the greatest terrestrial carbon sink. These boggy and busy pools of life used to be thought of as a nuisance for people and communities, drained of their water or dug up for peat fuel. Now, we understand the quiet service that wetlands provide us and the Read More...
