How artificially brightened clouds could cool down the earth

Clouds, however, naturally reflect the sun (it’s why Venus – a planet with permanent cloud cover – shines so brightly in our night sky). Marine stratocumulus clouds are particularly important, covering around 20% of the Earth’s surface while reflecting 30% of total solar radiation. Stratocumulus clouds also cool the ocean surface directly below. Proposals to Read more about How artificially brightened clouds could cool down the earth[…]

Four new DNA letters double life’s alphabet
