Smith, C. J.; Crook, J. A.; Crook, R. (2017): Impacts of stratospheric sulfate geoengineering on global solar photovoltaic and concentrating solar power resource. (in press). In Journal of Applied Meteorology and Climatology.

"We analyze results from the HadGEM2-CCS climate model with stratospheric emissions of 10 Tg yr-1 of SO2, designed to offset global temperature rise by around 1°C. A reduction in concentrating solar power (CSP) output of 5.9% on average over land is shown under SSI compared to a baseline future climate change scenario (RCP4.5) due to a decrease in direct radiation."

"I think that an advanced planetary civilization will modify their own planets to be more stable, to prevent asteroid impacts and dangerous climate fluctuations. I think we can look for engineered planets. I think that if we're around in 10 or 20,000 or 100,000 years, we will be engineering Earth. I think that when society gets planet-changing technology, it will either not last long because it can't handle that, or it will become able to manage themselves and their planet. Truly advanced civilizations, their planets will potentially be recognizable as planets that have been altered purposefully. We could start looking for technosignatures."

"In this study, I evaluate the impacts of SRM deployment on terrestrial ecosystem functions using a process-based ecosystem model (the Vegetation Integrative Simulator for Trace gases, VISIT) driven by the climate projections by multiple climate models. In the SRM-oriented climate projections, massive injection of sulphate aerosols into the stratosphere lead to increased scattering of solar radiation and delayed anthropogenic climate warming. The VISIT simulations show that canopy light absorption and gross primary production are enhanced in subtropics in spite of the slight decrease of total incident solar radiation."

"Here, we describe an alternative approach based on the large-scale industrial production of marine microalgae. When cultivated with proper attention to power, carbon, and nutrient sources, microalgae can be processed to produce a variety of biopetroleum products, including carbon neutral biofuels for the transportation sector and long-lived, potentially carbon-negative construction materials for the built environment."
