JAKARTA, Indonesia (AP) - U.S. Secretary of State John Kerry is putting climate change deniers in the same category as those who insist the Earth is flat.
Speaking in Indonesia today, Kerry says climate change may be the world's "most fearsome" weapon of mass destruction and urgent action is needed to combat it.
In a speech to Indonesian students, civic leaders and government officials in Jakarta, Kerry accused climate change deniers of using shoddy science and scientists to delay measures needed to reduce emissions of greenhouse gases.
He also argued that everyone and every country must take responsibility and act immediately.
Kerry argued that the cost of inaction to environments and economies will far outweigh even the significant expense of reducing greenhouse gas emissions that trap solar heat in the atmosphere and contribute to the Earth's rising temperatures.
