Targeted Marine Cloud Brightening Weakens Subsequent El Niño

Scientists Say This Climate Hack Could Stop El Niño Before It Starts

Researchers modeled the effect of marine cloud brightening on an emerging super El Niño and completely neutralized it.

Seeding clouds with seawater could prevent a super El Niño

A modelling study suggests marine cloud brightening could shade the eastern Pacific and reduce a global temperature spike from El Niño, but there could be unexpected consequences

Targeted marine cloud brightening weakens subsequent El Niño

Abstract Extreme events are often attributable to the compounding effects of anthropogenic warming and natural variability. Marine cloud brightening (MCB), a solar geoengineering proposal to reduce long-term warming, could theoretically mitigate extremes by instead targeting seasonal-to-multiyear phenomena, such as El Niño–Southern Oscillation (ENSO). Yet the effectiveness of regional MCB to deliberately modify ENSO has not been tested. By explo…

Scientists say seawater cloud seeding could prevent Super El Niño and reduce global warming

New Delhi: Scientists have proposed a new way to reduce the impact of a super El Niño by brightening clouds over the Pacific Ocean. A new modelling study has indicated that the ocean might be cooled enough by spraying fine seawater droplets into low-lying marine clouds to weaken the climate event before it peaks. The results suggest that the method could help mitigate extreme global warming associated with El Niño, but the researchers note that …

Using Seawater for Cloud Seeding: A Solution to Prevent Super El Niño Events

Innovative cloud brightening using ship exhaust particles could be a climate change solution NASA Earth Observatory Short-term geoengineering strategies, like enhancing cloud brightness over the eastern Pacific, have the potential to mitigate El Niño’s impacts and safeguard the global economy, potentially saving trillions of dollars. However, these interventions may disrupt natural cycles, leading to uneven [...] The post Using Seawater for Clou…

Could Geoengineering Work to Tamp Down Super El Niños?

With an anticipated "super" El Niño looming, a new study led by UC San Diego's Scripps Institution of Oceanography considers whether society could use a weather-altering technique as a tool to mitigate the floods, extreme heat and other events that El Niño would bring.
