Geoscientists in the United States are predominantly White. Progress towards diversification can only come with a concerted shift in mindsets and a deeper understanding of the complexities of race.
Scientists and policymakers must acknowledge that carbon dioxide removal can be small in scale and still be relevant for climate policy, that it will primarily emerge ‘bottom up’, and that different methods have different governance needs.
Governments disagree even on the current state of climate change engineering governance, as became clear at the 2019 United Nations Environment Assembly negotiations. They must develop mechanisms to provide policy-relevant knowledge, clarify uncertainties and head off potential distributional impacts.
The climate of South and East Asia is affected by anthropogenic aerosols, but the magnitude of the aerosol imprint is not well known. As regional emissions are rapidly changing, potential related climate risks must be quantified.
Social media is increasingly being used to share near-real-time analysis of emergent and sometimes hazardous geological events. Such open discussion can drive new research directions and collaborations for geoscientists.
