The catastrophic consequences of blocking the Sun cool the Earth

Blocking the sun to cool the Earth is not an effective way to solve it, because it can solve global warming, but it creates other concerns.

According to the Daily Mail, the current leading hypothesis is the ability to shoot sulphate particles sprayed into the atmosphere to block the sun , reducing the Earth's temperature.

Blocking sunlight will harm agriculture.

But later research on the Earth's time cooled because of volcanic eruptions, suggesting that this will cause serious harm to agriculture, the main source of human food.

Scientists conclude that blocking the sun will cause crop yields to drop significantly, since it is not an effective way to cope with global warming.

The study took a model of the Pinatubo volcano, spraying 20 million tons of sulfur dioxide (SO ₂ ) into the atmosphere. This causes the sun's sunlight to fall to 2.5% and thereby reduce the global temperature to half a degree centigrade.

But the research of scientists from Berkeley, California, also points out that this is not a feasible way.

One of the most possible methods is to block sunlight to cool the Earth.

'Shielding the Earth from the Sun will make the Earth cooler, but harmful to plants' , the researchers say. That's because plants also need light to grow.

The team linked yields of corn, soybeans, rice, and wheat from 105 countries during the 1979-2009 period to see how climate change impacts agriculture.

The team determined that lack of sunlight would reverse the goal of protecting plants from extreme temperatures . 'In the end, you go back to the starting point without solving the problem'.

Despite such conclusions, experts say that it is still necessary to test in practice to know exactly what happens, and other areas can benefit from cooling the Earth.
