2010s hottest decade in history, UN says as emissions rise again

Each of the last four decades has been hotter than the last

The World Meteorological Organization says 2019 is expected to be the second or third warmest year on record, concluding a decade of exceptional global heat.

According to the WMO, the global average temperature until October of 2019 was 1.1 degrees above the levels seen before the start of the industrial age in the late 18th century. "Climate change means more frequent droughts and extreme weather events in Germany,"said German Weather Service Vice President Paul Becker".

The report is released as countries meet in Madrid for the latest round of United Nations climate negotiations, known as "Cop25", amid pressure to increase their ambitions to cut the greenhouse gas emissions driving climate change.

"If we wanted to reach a 1.5 °C increase we would need to bend emissions and at the moment countries haven't been following on their Paris pledges", WMO Secretary General Petteri Taalas told reporters in Madrid, where envoys from nearly 200 countries were attending a two-week United Nations conference on the issue.

Oceans, which take in 90 % of the surplus warmth produced by greenhouse gases, at the moment are at their highest recorded temperatures.

The ocean heat was at record levels this year and tropical cyclone activity globally was also above average.

The WMO provisional statement on the state of the global climate also warns that sea levels are rising ever faster, ice is melting and "once in a century" heatwaves and floods are now becoming more regular occurrences.

Nations are at the moment in essential talks in Madrid geared toward finalising guidelines for the 2015 Paris local weather accord, which enjoins nations to work to restrict worldwide temperature rises to "well below" 2C. "Wildfires swept through the Arctic and Australia". According to the United Nations IPCC, the GHG concentrations must stabilise at 450 parts per million (ppm) Carbon dioxide if the planet is to have a 50% chance of avoiding a unsafe global average temperature rise of 2 degrees Celsius or more above pre-industrial levels. "The numbers will be higher if we continue our current behavior".

A part of the discussions in Madrid is geared toward getting nations to extend their local weather motion ambition forward of a deadline subsequent yr.

Friederike Otto, deputy director of the University of Oxford's Environmental Change Institute, said the WMO report "highlights that we are not even adapted to 1.1 degree of warming".

"And there is no doubt that this 1.1 degree is due to the burning of fossil fuels", she said.

Christian Aid's global climate lead Kat Kramer said the WMO report showed the need for concrete progress in Madrid.

"Delegates have no excuse to block progress or drag their feet when the science is showing how urgently action is needed", she said.
