The use of terrestrial geoengineering techniques, such as carbon capture, is necessary to keep the rise in global temperatures below 1.5 degrees Celsius, as per the Paris Agreement’s targets. Terrestrial geoengineering is different from atmospheric climate engineering: the latter does not remove the very source of the increased greenhouse effect, which are anthropogenic greenhouse gases. India and Canada must collaborate on carbon capture and propose multilateral regulations for unethical atmospheric climate engineering
