UN/Canadian-Media: The COVID-19 pandemic was not the only long-term crisis the world will remember from 2020. In terms of climate change, the year was also one of the three warmest on record and rivaled 2016 for the top spot, the UN weather agency said on Wednesday.
“The confirmation by the World Meteorological Organization (WMO) that 2020 was one of the warmest years on record is yet another stark reminder of the relentless pace of climate change, which is destroying lives and livelihoods across our planet”, said Secretary-General António Guterres.
He pointed out that at 1.2 degrees of warming above pre-industrial levels, the world is already witnessing unprecedented weather extremes in every region and on every continent.
“We are headed for a catastrophic temperature rise of 3 to 5 degrees Celsius this century”, he warned. “Making peace with nature is the defining task of the 21st century. It must be the top priority for everyone, everywhere.”
Powerful force La Niña, which began in late last year, is expected to continue into the early-middle part of 2021.
“The exceptional heat of 2020 is despite a La Niña event, which has a temporary cooling effect”, said WMO Secretary-General Prof. Petteri Taalas.
La Niña and El Niño effects on average global temperatures are typically strongest in the second year of the event.
“It is remarkable that temperatures in 2020 were virtually on a par with 2016 when we saw one of the strongest El Niño warming events on record”, he added. “This is a clear indication that the global signal from human-induced climate change is now as powerful as the force of nature”.
The extent to which the continued cooling effects of La Niña this year may temporarily diminish the overall long-term warming trend remains to be seen.
Following atypical patterns
WMO pointed to sustained heat and wildfires in Siberia, diminishing Arctic sea ice, and record-breaking hurricanes in the Atlantic as being among the climate events that most stood out in…
