Now that President Donald Trump has backed out of the Paris Climate Change agreement, employment prospects for bioethicists may pick up. Let me explain.

The boundaries of bioethics are very elastic, and on some maps they include care for the natural environment. I would predict that in the measure that scientists lose faith in a political solution to global warming, some will back geoengineering projects to cool the planet.

These include tactics such as injecting aerosols into the upper atmosphere, dumping iron filings into the sea to promote algal blooms, and machines to capture carbon dioxide. These involve significant risk and place great power in the calculations of technocrats. They need to be studied very carefully. As University of Chicago climate scientist Raymond Pierrehumbert said a few years ago, “I see lots [of geoengineering ideas] that are feasible but they all terrify me.”

A 2010 conference on the ethics of climate intervention at Asilomar, in California, addressed some of these issues using principles drawn from the famous Belmont principles of autonomy, beneficence, non-malificence and justice. And who knows more about these than bioethicists? Dust off those resumés.
