2016 will very likely be the hottest year on record and a new high for the third year in a row, according to the UN. It means 16 of the 17 hottest years on record will have been this century. The scorching temperatures around the world, and the extreme weather they drive, mean the impacts of climate change on people are coming sooner and with more ferocity than expected, according to scientists.
The World Meteorological Organization (WMO) report, published on Monday at the global climate summit in Morocco, found the global temperature in 2016 is running 1.2C above pre-industrial levels. This is perilously close to to the 1.5C target included as an aim of the Paris climate agreement last December.
The El Niño weather phenomenon helped push temperatures even higher in early 2016 but the global warming caused by the greenhouse gas emissions from human activities remains the strongest factor.

The record-smashing heat led to searing heatwaves across the year: a new high of 42.7C was recorded in Pretoria, South Africa in January; Mae Hong Son in Thailand saw 44.6C on 28 April; Phalodi in India reached 51.0C in May and Mitribah in Kuwait recorded 54.0C in July. Parts of Arctic Russia also saw extreme warming - 6C to 7C above average. Arctic ice reached its equal second-lowest extent in the satellite record in September while warm oceans saw coral mortality of up to 50% in parts of Australia’s Great Barrier Reef. Extreme weather and climate related events have damaged farming and food security, affecting more than 60 million people, according to the UN Food and Agriculture Organization. The level of CO2 in the atmosphere has also broken records in 2016, with May seeing the highest monthly value yet - 407.7 ppm - at Mauna Loa, in Hawaii.
