Scientists plan to save the planet from global warming by turning off the sun. They consider that slowing down the giant heat-emitting ball could be an effective weapon in the fight against climate change. Professor of earth science Peter Irvine, from UCL in London, said that the powerful volcanic eruption caused the global temperature to drop for several years by creating a hazy layer. of microscopic particles in the upper atmosphere that temporarily cover the sun.
He said that if humanity can artificially simulate the effects of an explosion, everyone can relax in the face of global warming. Research shows that intellectuals only need to lower the sun by about 1% to cool the Earth by 1 °C.
Blocking sunlight also prevents frozen parts of the world. Peter said: “We can replicate this effect in the fight against climate change. If countries do not begin to take this idea seriously, they may lose an important opportunity to reduce the risks of climate change.
It’s not just the expert who has such a great idea. The US government has launched a five-year research plan to study ways to change the amount of sunlight that reaches Earth, a process known as solar geoengineering, or solar reflection.
He considered spraying aerosols into the stratosphere (about 20 miles high) from a fleet of airplanes to create a fine mist that would float in the air and reflect some of the Sun’s radiation back into the space.
The cheapest option – spraying sulfur dioxide into the atmosphere – can have harmful effects on the environment and human health, damage the ozone layer, produce acid deposits and can cause an increase in respiratory disease.
But scientists worry about humanity exceeding its emissions targets; They say research is essential to determine how best to balance these risks with a potentially catastrophic increase in Earth’s temperature.
