Abstract Stratospheric aerosol injection is a potential method of climate intervention to reduce risk as decarbonization efforts continue. However, possible ecosystem impacts from the strategic design hypothetical scenarios are poorly understood. Two recent Earth system model simulations depict policy-relevant stratospheric with similar global temperature targets, but 10-year delay in deployment. Here we show this leads distinct ecological profiles through speeds, which describe rate...

Stratospheric aerosol injection (SAI) is a proposed form of climate intervention that would release reflective particles into the stratosphere, thereby reducing solar insolation and cooling planet. The response to SAI not well understood, particularly on short-term time horizons frequently used by decision-makers planning practitioners assess information. We demonstrate two framings explore in decade after deployment modeling experiments with parallel no-SAI simulations. first framing, which...

Abstract Data-rich fields such as the Earth sciences benefit from transparent, structured documentation. Based on best practices in software engineering, we adapt for a questionnaire format known datasheet which guides author to document both biases and technical information dataset. Datasheets complement existing standards documentation by eliciting about aspects together within scope of project. This combination is not easily obtained elsewhere provides transparency, aids reproducibility,...

Abstract Stratospheric aerosol injection (SAI) is a potential method of climate intervention to reduce risk as decarbonization efforts continue. Two recent Earth system modeling experiments depict policy-relevant SAI scenarios with similar temperature targets (near 1.5°C), but deployment delayed by 10 years between experiments. This relatively short delay leads highly distinct profiles ecological from speeds. Climate speeds when global maintained are indistinguishable on planetary scale...

Abstract Ice habit diagrams published prior to 2009—and many since—do not accurately describe in situ observations of ice shapes as a function temperature and moisture. Laboratory studies analysis field by Bailey Hallett series papers 2002, 2004, 2009 corrected several errors from earlier studies, but their work has been widely disseminated. We present new, simplified diagram based on Hallett’s that focuses growth forms arising the underlying surface processes which mass is added crystal:...

Current global actions to reduce greenhouse gas emissions are very likely be insufficient meet the climate targets outlined under Paris Agreement. This motivates research on possible methods for intervening in Earth system minimize risk while decarbonization efforts continue. One such hypothetical intervention is stratospheric aerosol injection (SAI), where reflective particles would released into stratosphere cool planet by reducing solar insolation. The response SAI not well understood,...
