Crop failure rates in a geoengineered climate: impact of climate change and marine cloud brightening [PDF]

Environmental Research Letters, 2015
The impact of geoengineering on crops has to date been studied by examining mean yields. We present the first work focusing on the rate of crop failures under a geoengineered climate.

First Simulations of Feedback Algorithm‐Regulated Marine Cloud Brightening

Geophysical Research Letters
Feedback control algorithms are important tools in climate intervention simulation design because they facilitate “top‐down” design, in which climate goals (often temperatures) are prescribed and a strategy chosen to meet the target.

Targeted marine cloud brightening can dampen El Niño

Many record-breaking climate extremes arise from both greenhouse gas-induced warming and natural climate variability. Marine cloud brightening, a solar geoengineering strategy originally proposed to reduce long-term warming, could potentially mitigate extreme events by instead targeting seasonal phenomena, such as El Niño-Southern Oscillation (ENSO ...

Effect of regional marine cloud brightening on land climate

Environmental Research Letters
Marine cloud brightening (MCB) is one of the proposed climate intervention methods aiming to reduce anthropogenic warming. In this study, we use the CESM Earth system model to examine the land climate consequences of regional MCB. MCB is implemented from

Effect of Regional Marine Cloud Brightening Interventions on Climate Tipping Elements

Geophysical Research Letters, 2023
It has been proposed that increasing greenhouse gas (GHG) driven climate tipping point risks may prompt consideration of solar radiation modification (SRM) climate intervention to reduce those risks.

A Review of Some Experimental Spray Methods for Marine Cloud Brightening

International Journal of Geosciences, 2013
Marine Cloud Brightening (MCB), should it ever need to be deployed, envisions the formation of 1017salt Cloud Condensation Nuclei (CCN) per second coming from each of several thousand vessels deployed worldwide. The creation of this many nuclei on such a vast scale, from micron- or submicron-sized seawater droplets, preferably mono-disperse, poses a ...

The Effects of Marine Cloud Brightening on Seasonal Polar Temperatures and the Meridional Heat Flux [PDF]

ISRN Geophysics, 2012
Marine cloud brightening (MCB) is one of several proposed solar radiation management (SRM) geoengineering schemes designed to ameliorate some of the undesirable effects of climate change, for example polar ice loss and associated increased sea levels.

A protocol for model intercomparison of impacts of marine cloud brightening climate intervention [PDF]

Geoscientific Model Development
A modeling protocol (defined by a series of climate model simulations with specified model output) is introduced. Studies using these simulations are designed to improve the understanding of climate impacts using a strategy for climate intervention (CI)

Impacts of marine cloud brightening scheme on climatic extremes in the Tibetan Plateau [PDF]

Open Geosciences, 2023
As an ecologically fragile plateau and major water source in Asia, the Tibetan Plateau (TP) has grown warmer over recent decades, contributing to frequent occurrence of extreme climate events.
