London ? British tycoon Richard Branson dangled a $25 million prize before the world’s top scientists Friday seeking to spur research into devising ways to suck greenhouse gases out of the air.

Former Vice President Al Gore lent his support to the challenge, which came a week after a landmark report by the world’s leading climate scientists and government officials warned that global warming will continue, creating a far different planet in 100 years.

“Man created the problem, therefore man should solve the problem,” Branson said.

Branson hopes his offer will lead to a viable machine for vacuuming the Earth’s atmosphere of carbon dioxide, one of the greenhouse gases blamed for rising temperatures.

It’s an idea many scientists and the Intergovernmental Panel on Climate Change say may be possible someday.
