What are some potential side effects of cloud brightening?

Side effects There is some potential for changes to precipitation patterns and amplitude, although modeling suggests that the changes are likely less than those for stratospheric aerosol injection and considerably smaller than for unabated anthropogenic global warming.

Can marine cloud brightening reduce coral bleaching?

Scientists Say Brighter Clouds Might Protect Great Barrier Reef From Climate Crisis. The idea behind the ‘Marine Cloud Brightening for the Great Barrier Reef’ project is to reduce the risk of coral bleaching in the short term while global greenhouse gas emissions are cut and temperatures stabilized.

How do you make clouds whiter?

10 real ways to get white clothes whiter

1. Separate your colors.
2. Don’t use too much detergent.
3. Consider optical brighteners.
4. Dry clothes on low heat.
5. Only use bleach on cotton.
6. Try lemon juice.
7. Add borax.
8. Try automatic dishwasher detergent.

What are the pros of marine cloud brightening?

Brighter clouds could theoretically diminish the solar radiation reaching the Earth’s surface and would therefore reduce the temperature of the atmosphere and oceans because they absorb less solar energy.

Who invented marine cloud brightening?

Marine cloud brightening (MCB), one of several solar radiation management (SRM) geoengineering ideas involving the production of a global cooling to compensate for the warming associated with continuing fossil fuel burning, was first postulated by Latham [1,2].

What is cloud brightening geoengineering?

cloud whitening, also called cloud brightening or marine cloud brightening, untested geoengineering technique designed to increase the reflectance of Earth’s cloud cover to reduce the amount of incoming solar radiation striking Earth’s surface.

How does cloud brightening work?

How do you brighten clouds? A specially-designed seawater sprayer, which works a bit like a snow-making machine, uses surrounding seawater to generate hundreds of trillions of microscopic sea salt crystals. These crystals float into the sky to form a fog and bolster the existing clouds’ reflectivity.

What is the water temperature in the Great Barrier Reef?

Coral needs warm water to live and grow, and the sea around the Great Barrier Reef maintains a steady water temperature of between 71F or 22C to 28F or 82C throughout the year. Diving, surfing and sailing are all popular pastimes in this glorious region, and you’re almost guaranteed great conditions.

What is marine cloud brightening and marine cloud engineering?

Marine cloud brightening also known as marine cloud seeding and marine cloud engineering is a proposed solar radiation management climate engineering technique that would make clouds brighter, reflecting a small fraction of incoming sunlight back into space in order to offset anthropogenic global warming.

Why is cloud brightening more effective at sea than on land?

These would then act as cloud condensation nuclei, increasing the cloud albedo . The marine environment has a deficit of cloud condensation nuclei due to lower levels of dust and pollution at sea, so marine cloud brightening would be more effective over the ocean than over land.

Does cloud-brightening actually work?

The trial was not designed to test the effectiveness of cloud-brightening itself, but Daniel Harrison of Southern Cross University, who led the project, told Guardian Australia it had successfully demonstrated that the delivery system worked.

What is cloud-brightening and how can it help corals?

The cloud-brightening approach is just one of 43 concepts being funded under a $150m government-backed research and development program announced on Thursday. Scientists are racing to find measures that could be used to reduce the impact of rising ocean temperatures on corals caused by global heating.
