It is reported that the White House Office of Science and Technology Policy is coordinating a five-year research program that aims to study reducing light arriving on Earth in response to global warming , which includes spraying particles into the atmosphere to reflect sunlight back to space (a process also known as sunlight reflection) - a plot similar to the plot code-named "Operation Dark Storm" in the movie "The Matrix 4". According to reports, if the plan is implemented, it may cost $10 billion a year.
U.S. President Biden formulated the research plan in the 2022 spending plan signed in March this year. The study plan will evaluate alternative climate interventions, including spraying aerosol into the stratosphere to reflect sunlight back to space. The current idea of this study appears to be to spray sulfur dioxide into the atmosphere, it is reported. It is well known that sulfur dioxide is a gaseous air pollutant composed of sulfur and oxygen that can produce bright haze and reflect sunlight back. Therefore, it is able to cool the earth by blocking the sun – which makes it a perfect candidate for White House to deal with climate change.
It is reported that the idea of sunlight reflection first appeared in a report to then-US president Lyndon Johnson in 1965. The report said that it would cost $500 million a year to change the Earth's reflectivity by 1%. Decades have passed, and the estimated sunlight reflection has become a 1°C cooling Earth, which will cost $10 billion a year.

, in New Jersey also published a paper on this technology in 2020. Scientists propose spraying sulfur dioxide into the stratosphere over the world to form a cloud of sulfuric acid that blocks solar radiation. The study also points out that global warming can be maintained at a safe level by adjusting the amount of sulfur dioxide sprayed every year.
1815, Tambora volcano located in Indonesia erupted, spraying a large number of sulfur dioxide clouds into the atmosphere, which caused the temperature in the entire northern hemisphere to drop by 3 degrees Celsius.
However, spraying sulfur dioxide into the atmosphere can have harmful effects on the environment and human health. It should be clear that sunlight reflection is not a solution to climate change, and reducing emissions remains the top priority. "If you don't look at what it (the country) does in reducing emissions, you can't tell what the country has done to change sunlight radiation." Pastor, executive director of the Carnegie Climate Governance Initiative in the United States, said, "Sun reflection will never become a solution to the climate crisis."
