United Nations: Kovid-19 lockdown dropped pollutants, not CO2 levels

Geneva: The slowdown in industrial activity associated with the coronavirus epidemic has cut emissions of pollutants and heat-trapped greenhouse gases, but has not reduced their record levels in the atmosphere, the United Nations Meteorological Agency said on Monday.
The World Meteorological Organization pointed to a record-setting increase of carbon dioxide emissions in recent years, but warned that any reduction in levels would take years to materialize as a result of the epidemic-related industrial recession.
The organization also said that it might be best if countries are able to reduce their greenhouse gas emissions to zero.
“The lockdown-related decline in emissions is just a small nap on the long-term graph. WMO Secretary General Perterty Talas said that we need to tighten the level on Monday after releasing the latest edition of the organization’s annual greenhouse gas bulletin.
“COVID-19 epidemic is not a solution to climate change.” The WMO cited estimates from the Global Carbon Project that indicated that daily carbon dioxide emissions could fall by up to 17% worldwide during the period of lockdown, when people in many countries were forced to stay indoors. But figures for the full year remain unclear, and WMO said preliminary estimates indicate annual global emissions reductions of between 4.2% and 7.5%.
The lockdown has cut emissions of many pollutants and greenhouse gases such as carbon dioxide. But changes in CO2 concentrations – the result of cumulative past and present emissions – are actually no larger than the normal year-to-year fluctuations in the carbon cycle and the amount of carbon soaked by vegetation and oceans.
“There is a slight plateau in the use of carbon, which is a little positive,” Talas said in a video news conference. “It’s a very slow process,” he said. The WMO said carbon dioxide levels rose again in 2019, which Talus called a “record rate of increase”, a concentration of 410 million per million, four years after it reached the top of 400 parts per million.
Talas praised efforts by some countries to reach carbon neutrality in the coming years.
