United Nations says current decade hottest in history as emissions rise

2010s set to be hottest decade in history: UN report

It said, "Concentrations of carbon dioxide in the atmosphere hit a record level of 407.8 parts per million (ppm) in 2018 and continued to rise in 2019".

The past decade is nearly certain to be the hottest on record, weather experts warned on Tuesday, painting a bleak picture of vanishing sea ice, devastating heatwaves and encroaching seas in a report launched at a climate summit in Spain.

Average temperatures for the five-year (2015-2019) and 10-year (2010-2019) periods are nearly certain to be the highest on record.

In October, the global mean sea level reached its highest on record, fueled by the 329 billion tons of ice lost from the Greenland ice sheet in 12 months.

Every of the final four a few years has been hotter than the final.

The analysis by the United Nations meteorological agency notes the effect of warmer temperatures on weather phenomena like hurricanes, flooding and other extreme events that have displaced millions in 2019 and threatened millions more with food insecurity.

And the WMO report also emphasized that weather disasters have displaced millions of people this year.

"On a day-to-day basis, the impacts of climate change play out through extreme and "abnormal" weather and once again in 2019 weather and climate related risks hit hard".

"Heatwaves and floods which used to be "once-in-a-century" events are becoming more regular occurrences", WMO Secretary-General Petteri Taalas said in a statement.

At simply 1C hotter than pre-industrial occasions, 2019 has already seen lethal heatwaves in Europe, Australia and Japan, superstorms devastate southeast Africa, and wildfires rage uncontrolled in Australia and California. COP25 renews the call to join forces to adopt the 2015 Paris Agreement, which aims at curbing the rise in global temperatures to a maximum of two degrees Celsius.

The organisation notes that 2019 rounds off a decade of "exceptional global heat, retreating ice and record sea levels driven by greenhouse gases from human activities". The study further found that 25% of the rise in sea levels by 2030 will be caused by emissions from five territories in the preceding 40 years, namely India, Russia, China, the U.S. and European Union.

Even when all Paris pledges have been honoured, Earth continues to be on the right track to be greater than 3C hotter by the top of the century.

"There is no indication of a fade out of the warming", Taalas told reporters.

Half of the discussions in Madrid is geared toward getting nations to place better their climate action ambition sooner than a decrease-off date next year.

Friederike Otto, deputy director of the College of Oxford's Environmental Change Institute, mentioned the WMO report "highlights that we're not even tailored to 1.1 diploma of warming".

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