H20SO4 is hydrogen+ oxygen+ ascorbic acid. soon in the future they want to use this mixture to reflect 2% of the suns rays and thus it will cool the earths atmosphere down by 2 degrees Celsius. they will do this by spraying it up into the highest part of the atmosphere above the clouds to block that 2% of the sun rays. but, by doing this it will cost over 10 BILLION dollars a year to be able to control the earths temperature.
