Scientists in the US have tried to reflect some of the sun's rays into space to temporarily cool the Earth after the planet experienced its hottest year on record in 2023. This is stated in the New York Times report.
The scientists used cloud clearing technology, which makes clouds brighter so that they reflect a small amount of sunlight and, as a result, lower the temperature in a certain area. If the technology proves successful, several devices could be placed in the sky above the oceans to reduce the temperature of the water in the rising sea.
On April 2, researchers at the University of Washington launched a high-speed mist of salt particles into the sky from a snowplow-like device aboard a decommissioned aircraft carrier in San Francisco. The experiment was conducted as part of a secret project called CAARE.
The idea was to use clouds as a mirror to reflect sunlight, a concept explained by British physicist John Latham in 1990. He proposed creating a fleet of 1,000 ships that would travel around the world spraying droplets of seawater into the air to reflect the sun's heat and lower the Earth's temperature.
Although some argue that this process can balance global warming caused by increased C02 content, some scientists believe that the results of the solar modification method are difficult to predict.
According to some scientists, excessive use of technology could change climate patterns over time. For example, changing ocean temperatures can affect marine biology and rainfall patterns, increasing rainfall in one region and decreasing it in another.
Last year, scientists warned: if a strong greenhouse effect begins on Earth, the evaporation of just 10 meters of the surface of the oceans will lead to an increase in atmospheric pressure at ground level by 1 bar. In a few hundred years, the temperature on Earth can rise to 500 °C. Eventually, the pressure at ground level will reach 273 bar and the temperature will rise to 1500 °C, causing all the oceans to evaporate.
