Аccording to The Telegraph, the UK government is set to approve experiments aimed at reducing sunlight as part of efforts to combat global warming. The projects include injecting aerosols into the atmosphere and brightening clouds to reflect more sunlight back into space.
The UK government is set to approve experiments to reduce sunlight as part of efforts to combat global warming. These projects include injecting aerosols into the atmosphere and brightening clouds to reflect more sunlight back into space.
The initiative is backed by £50 million in funding, with the first tests expected to be announced in the coming weeks. Scientists emphasize that the experiments will be safe by design, with strict requirements on duration and reversibility.
Critics argue that geoengineering could have unintended consequences and distract from efforts to reduce carbon emissions. However, researchers warn that carbon dioxide levels are not decreasing fast enough, making additional measures necessary.
One major area of research is Sunlight Reflection Methods (SRM), which includes Stratospheric Aerosol Injection (SAI)—releasing tiny particles into the stratosphere to reflect sunlight. Another approach is Marine Cloud Brightening (MCB), where ships spray sea-salt particles into the sky to enhance cloud reflectivity.
Scientists have observed that clouds above shipping routes are brighter than usual due to pollution, which has contributed to a cooling effect. When regulations reduced sulphur dioxide emissions in 2020, global temperatures spiked, suggesting that atmospheric modifications could influence climate patterns.
