Scientist proposes 'colossal refrigeration system' to stave of global-warming - International Business Times -

A little known Maryland scientist has made public a patent to solve one of man's most enduring and daunting problems: global warming.

Ron Ace, a 69-year-old, has been researching the earth's climate for years and has found what he calls the most "practical, nontoxic, affordable, rapidly achievable" and beneficial way to curb global warming and a resulting catastrophic ocean rise.

Ace proposes to spray gigatons of sea-water into the air and in effect, build a "a colossal refrigeration system with a 100,000-fold performance multiplier." He contends a number of positive effects would be in action at the same time to help stave off warming.

"The Earth has a giant air-conditioning problem," he said. "I'm proposing to put a thermostat on the planet."
