Planet is storing more heat than it can release, UN warns

The amount of heat trapped by the Earth has reached record levels. According to the UN's annual State of the Climate report, published this Monday, the last 11 years have been the warmest ever recorded. For the first time, the World Meteorological Organization is warning of a growing "energy imbalance", driven by rising greenhouse gas emissions. Scientists also fear that a natural warming phase called El Niño could soon bring further heat records.
