UN: World dealing with ‘catastrophic’ temperature rise this century


Global temperatures in 2020 have been among the many highest on report and rivalled 2016 as the most popular 12 months ever.The world is on track for a “catastrophic” temperature rise this century, the United Nations has warned.
Global temperatures in 2020 have been among the many highest on report and it rivalled 2016 as the most popular 12 months ever, in response to worldwide information compiled by the UN’s World Meteorological Organization (WMO).
The warmth got here at the same time as a world financial slowdown from the COVID-19 pandemic minimize deeply into emissions from fossil fuels, including proof that carbon dioxide concentrations already within the ambiance have set the planet on a warming observe.
The relentless tempo of local weather change is “destroying lives”, mentioned Secretary-General Antonio Guterres on Thursday because the WMO mentioned 2011 to 2020 was the warmest decade recorded.
“We are headed for a catastrophic temperature rise of 3-5 [degrees Celsius] this century … making peace with nature is the defining task of the 21st century. It must be the top priority,” Guterres mentioned.
The WMO report included information from the US National Oceanic and Atmospheric Administration (NOAA) and the UK Met Office, each of which ranked 2020 because the second-warmest 12 months on report, as a cooling development known as La Nina did not tame international temperatures.

The La Nina cool part of the Pacific Ocean floor temperatures cycle “put a brake on the heat only at the very end of the year”, the WMO mentioned.
It mentioned the common international temperature in 2020 was about 14.9 levels Celsius (58.eight levels Fahrenheit).
‘La Nina to continue’
The WMO mentioned the standout climate options of 2020 have been the sustained warmth and wildfires in Siberia and the low Arctic sea ice extent, plus the record-breaking Atlantic hurricane season.
La Nina is predicted to proceed into early to mid-2021.
“It is remarkable that temperatures in 2020 were virtually on a par with 2016 when we saw one of the strongest El Nino warming events on record. This is a clear indication that the global signal from human-induced climate change is now as powerful as the force of nature,” mentioned WMO Secretary-General Petteri Taalas.
“Heat-trapping gases in the atmosphere remain at record levels and the long lifetime of carbon dioxide, the most important gas, commits the planet to future warming.”
The WMO will publish its State of the Climate in 2020 ultimate report in March.
