An annual report released by the United Nation's World Meteorological Organization on Tuesday also notes the grave environmental threat posed by "ocean acidificaton," whereby roughly a quarter of all C02 emissions are absorbed by the earth's oceans.

W.M.O. Secretary-General Michel Jarraud stressed the need for immediate action.

We know without any doubt that our climate is changing and our weather is becoming more extreme due to human activities such as the burning of fossil fuels. The Greenhouse Gas Bulletin provides a scientific base for decision-making... Pleading ignorance can no longer be an excuse for not acting.”

Republican Presidential candidate Kentucky Senator Rand Paul mocked former Secretary of State Hillary Clinton in an interview with Fox News on Friday for her assertion that climate change was the most sweeping challenge the country faces.
