To the Editor:
For two centuries, we have been pumping gigatons of carbon from fossil pools into the atmosphere. That carbon dioxide is now contributing to global climate change that threatens to make our planet uninhabitable. That same carbon dioxide is simultaneously causing an acidification of our oceans. If we were to address global warming by blocking some of the incident sunlight but fail to address the acidification of the oceans, we could end up just as extinct. Blocking incident sunlight cannot be enough. We have to actively take greenhouse gases out of the atmosphere. Carbon sequestration--whether as carbon dioxide or anthropogenic peat--would ameliorate global warming and the acidification of our oceans simultaneously.
