According to one professor, we can stop global warming if we used a new super white paint.
The problem though, is we would need to cover at least 1% of the earth's surface with the paint.
But just how big is 1-2% of the Earth's surface?
For reference, the total land area of the United States is just over 3.5 million square miles, so we'd need to cover the country in white paint from sea to paint-stained sea.
If we assume the new paint acts like commerical paint, as the Purdue researchers suggest, a gallon would cover about 400 square feet, we would need roughly 139 billion gallons of the super-duper white paint to cover just 1% of the Earth's surface.
