U.S. Secretary of State John Kerry says climate change may be the world's ``most fearsome'' weapon of mass destruction and urgent action is needed to combat it. He compares those who deny its existence or question its causes to people who insist the Earth is flat.
In a speech Sunday to Indonesian students, civic leaders and government officials in Jakarta, Kerry laid into climate change deniers. He says they use shoddy science to delay measures needed to reduce emissions of greenhouse gases at the risk of imperiling the planet.
Kerry says quote ``We simply don't have time to let a few loud interest groups hijack the climate conversation.''
He argues the cost of inaction outweighs the expense of reducing greenhouse gases that contribute to the Earth's rising temperatures.
