According to the report, scientists used cloud brightening technique. In this technique, the clouds are made bright so that they can reflect a small part of the sunlight and the temperature of that area reduces. If the experiment is successful, it can be used in future to reduce the rising temperature of the ocean.
This is how the experiment was done
According to the report, on April 2, researchers at the University of Washington used a snow-machine-like device on a retired aircraft carrier in San Francisco. With its help, a mist of salt particles was released into the sky at high speed.
This experiment was part of a secret project named CAARE. The purpose of the experiment was to make the clouds bright and use them as mirrors, so that the sunlight falling on the Earth is reflected back into space.
However, the biggest question is whether it is effective in dealing with global warming. Some claim that this process can balance global warming caused by the increase in C02. Many scientists believe that it would be too early to predict its results right now. What American scientists did is just an experiment, but opens new possibilities for the future.
