Last year the hottest ever, and humans are to blame

By Emily Beament

Last year was the hottest year on record globally, beating 2015's exceptionally high temperatures, the World Meteorological Organisation (WMO) said yesterday.

The global average temperature for the year was 1.1C higher than pre-industrial levels and about 0.07C higher than the previous record set in 2015, the organisation added.

Along with record temperatures, other long-term indicators that humans are changing the climate reached new heights, including levels of greenhouse gases and melting ice, the WMO explained.

WMO secretary general Petteri Taalas said: "It was an extreme year for the global climate and stands out as the hottest year on record, but temperatures only tell part of the story.

"Long-term indicators of human-caused climate change reached new heights in 2016.

"Carbon dioxide and methane concentrations surged to new records. Both contribute to climate change.

"We have also broken sea ice minimum records in the Arctic and Antarctic."
