Secretary of State John Kerry has spoken about the dangers of climate change, calling it a weapon of mass destruction.
Kerry called on Indonesia's leaders to work on cutting greenhouse emissions, calling climate change "catastrophic".
He said that climate change could now be considered another weapon of mass destruction, perhaps the world's most fearsome weapon of mass destruction.
According to ABC News, Kerry said that China and the United States are the cause of 40 percent of the world's greenhouse gases.
Kerry called on the Indonesian leaders to work on lowering greenhouse emissions in a country vulnerable to serious storms.
Kerry cited the intense Typhoon Haiyan, which killed thousands in Indonesia, as the kind of severe storms the country can expect if climate change worsens.
He said that there was scientific proof of climate change threatening not only the environment, but also the world economy, the report added.
