Cocoons around stars, Sun and Earth

Cocoons around stars, the Sun and Earth: the zodiacal light, 1816, and global warming.

In the 1970s infrared surveys showed that many stars are surrounded by clouds of dust. In 1982 scientists began to worry about the prospect of nuclear winter, severe cooling caused by dust thrown up during a nuclear war. Dust from the 1815 Tambora volcanic eruption resulted in ‘the year without a summer’, 1816. The 1983 IRAS survey mapped the infrared radiation from the Sun’s debris disk, long known about indirectly because of the zodiacal light. In 2001 scientists on the UN’s International Panel for Climate Change began to predict global warming and climate change caused by rising CO2 levels in the atmosphere.

Michael Rowan-Robinson, an international expert on dust shells around stars and on the Sun’s debris disk, draws together the impact of these dust and molecular cocoons around stars, the Sun and Earth, and warns of the urgent need to get to net zero.
