Oceanographer: To substantially reduce the amount of carbon dioxide in Earth's atmosphere, carbon dioxide should be captured and pumped deep into the oceans, where it would dissolve. ███ █████ █████ █████ ██ █████ ██████ █████ █████████ ██ ███ ████ ███ ██████ █████ ████ ███ ████████ ██ ███ ██████ ███████ ██████ ████ ████ ██████ █████ ██ ███████ █████ ███ ██████████
Summary
If we want to reduce carbon dioxide in the atmosphere, we should pump it deep into the ocean. Why? Cold, deep water takes a long time to mix with warm, surface water, and this ensures that the carbon dioxide would be trapped for a long time.
Notable Assumptions
In her reasoning, the oceanographer has made the mixing of cold and warm water necessary to release carbon dioxide. But what if it isn’t, and carbon dioxide can be released whether the water mixes or not? We need to know that this mixing is necessary for carbon dioxide release.
