CO2 levels surged in 2020, says UN
Greenhouse gas concentrations hit a record last year and the world is “way off track” on capping rising temperatures, the UN said on Monday, showing the task facing climate talks in Glasgow aimed at averting dangerous levels of warming.
A report by the UN World Meteorological Organisation (WMO) showed carbon dioxide levels surged to 413.2 parts per million in 2020, rising more than the average rate over the last decade despite a temporary dip in emissions during Covid-19 lockdowns.
WMO secretary-general Petteri Taalas said the current rate of increase in heat-trapping gases would result in temperature rises “far in excess” of the 2015 Paris Agreement target of 1.5 degrees Celsius above the pre-industrial average this century.
“We are way off track,” he said. “We need to revisit our industrial, energy and transport systems and whole way of life,” he added, calling for a “dramatic increase” in commitments at the COP26 conference beginning on Sunday.
