Billionaire entrepreneur, Elon Musk, has announced a prize of $100 million to any investor who is able to find a solution to battle global warming.

He has given a period of four years for investors to come up with successful ideas to win the prize money. The "largest incentive prize in history" will last till Earth Day, 2025. Elon Musk has urged people to come ahead with ideas on fighting global warming by removing carbon dioxide from the atmosphere and ocean.

"I think this is one of those things that is going to take a while to figure out what the right solution is," he said. "And especially to figure out what the best economics are for CO2 removal," said Elon Musk.

The contenders are required to have a plan to sustain the technology for at least the next 100 years.
