They've already been doing this on a daily basis for decades. They're just pretending that it something they're just starting to do now.
“’It is important to recognize that we are at present involved in a large project of inadvertent "geoengineering" by altering atmospheric chemistry, and it does not seem inappropriate to inquire if there are countermeasures that might be implemented to address the adverse impacts. Our current inadvertent project in "geoengineering" involves great uncertainty and great risk. Engineered countermeasures need to be evaluated but should not be implemented without broad understanding of the direct effects and the potential side effects, the ethical issues, and the risks. Some do have the merit of being within the range of current short-term experience, and others could be "turned off" if unintended effects occur.” - Policy Implications of Greenhouse Warming: Mitigation, Adaptation, and the Science Base (1992) by the Panel on Policy Implications of Greenhouse Warming, the National Academy of Sciences, the National Academy of Engineering, and the Institute of Medicine
