Meteorologists Take Geoengineering Seriously


Geoengineering received a big boost this week. The American Meteorological Society released a major statement Monday on the topic, making these recommendations:

1. Enhanced research on the scientific and technological potential for geoengineering the climate system, including research on intended and unintended environmental responses.
2. Coordinated study of historical, ethical, legal, and social implications of geoengineering that integrates international, interdisciplinary, and intergenerational issues and perspectives and includes lessons from past efforts to modify weather and climate.
3. Development and analysis of policy options to promote transparency and international cooperation in exploring geoengineering options along with restrictions on reckless efforts to manipulate the climate system.

The AMS is a respected scientific body here in the US, and a statement of this kind certainly gives credence to the possibility of a major, well-funded, possibly federal geoengineering research program. It also comes on the heels of a National Academy of Sciences workshop in which leading experts debated the merits of such a research program.

Some geoengineering critics (and there are plenty of them) say investment in this kind of research will only distract from mitigation efforts. I disagree, and now, so does AMS. And I think the Society responds well to that argument with this point:

Geoengineering will not substitute for either aggressive mitigation or proactive adaptation, but it could contribute to a comprehensive risk management strategy to slow climate change and alleviate some of its negative impacts. The potential to help society cope with climate change and the risks of adverse consequences imply a need for adequate research, appropriate regulation, and transparent deliberation.

THE BIG QUESTION...

as we head into 2020 is whether politics and media will be a billionaires’ game, or a playing field where the rest of us have a shot. That's what Mother Jones CEO Monika Bauerlein tackles in her annual December column—"Billionaires Are Not the Answer"—about the state of journalism and our plans for the year ahead.
