Global temperatures in 2020 among highest on record: WMO – Times of India

WASHINGTON: Global temperatures in 2020 had been among the highest on file and rivaled 2016 as the most popular yr ever, based on worldwide knowledge compiled by the World Meteorological Organization and launched on Thursday.
The warmth got here at the same time as a world financial slowdown from the COVID-19 pandemic lower deeply into emissions from fossil fuels, including proof that carbon dioxide concentrations already in the atmosphere have set the planet on a warming observe.
The WMO report included knowledge from the U.S. National Oceanic and Atmospheric Administration (NOAA) and the UK Met Office, each of which ranked 2020 because the second-warmest yr on file, as a cooling development referred to as La Niña did not tame world temperatures. NASA, whose knowledge was additionally included, mentioned 2020 tied with 2016 because the warmest yr on file.
The information is “yet another stark reminder of the relentless pace of climate change, which is destroying lives and livelihoods across our planet,” U.N. Secretary General António Guterres mentioned. “Making peace with nature is the defining task of the 21st century.”
WMO mentioned the variations in common world temperatures among the three warmest years, 2016, 2019 and 2020, had been indistinguishably small. The common world temperature in 2020 was about 14.9 C (59 F), or about 1.2 C above the 1850-1900 pre-industrial stage. That approached the popular 1.5 C decrease restrict of temperature enhance the 2015 Paris Agreement on local weather sought to avert.
All 5 datasets surveyed by WMO confirmed that 2011-2020 was the warmest decade on file, and NOAA mentioned the seven warmest years since file-preserving started in 1880 have occurred since 2014.
There is at the least a one-in-five likelihood that the typical world temperature will quickly exceed that restrict by 2024, based on a WMO evaluation, led by the UK Met Office.
Greenhouse gasoline emissions in the United States, the second- main supply of the air pollution after China, fell greater than 10% final yr, the most important drop in the post-World War II period, because the coronavirus crippled the financial system, the Rhodium Group mentioned this week.
The dip shouldn’t be seen as a assure the United States can simply meet its pledge underneath the Paris settlement to chop emissions by 28% by 2025. President Donald Trump pulled the United States from the accord, however President-elect Joe Biden has promised to rejoin after taking up on Jan. 20.
The WMO, a U.N. company, relied on knowledge from observing websites and ships and buoys from NOAA and NASA and the United Kingdom’s Met Office Hadley Centre and the University of East Anglia’s Climatic Research Unit.
It additionally tapped datasets from the European Centre for Medium Range Weather Forecasts and its Copernicus Climate Change Service, and the Japan Meteorological Agency.
