Biggest drop in CO2 emissions since WWII due to Covid-19:

Though scientists expect carbon emissions to fall by 5% in 2020, the coronavirus pandemic is having very little impact on climate change, according to the World Meteorological Organization.

A new forecast produced by climate experts of the Global Carbon Projectwhich produces widely-watched annual emissions estimates, predicts that carbon dioxide emissions could fall by the largest amount since World War Two.

CO2 emissions drop by 5%?

Rob Jackson, a professor of Earth system science at Stanford University in California who chairs the Project, said carbon output could fall by more than 5% this year – the first dip since a 1.4% reduction after the 2008 financial crisis.

“Neither the fall of the Soviet Union nor the various oil or savings and loan crises of the past 50 years are likely to have affected emissions the way this crisis is,” he added.

But experts warn that without structural change, the emissions declines caused by coronavirus could be short-lived and have little impact on the concentrations of carbon dioxide that have accumulated in the atmosphere over decades.

Global warming

Any reductions in pollution and carbon dioxide emissions are likely to be temporary, said Lars Peter Riishojgaard, from the infrastructure department of the World Meteorological Organization (WMO), a United Nations agency based in Geneva.

“It does not mean much for climate,” he told a virtual press conference.

Riishojgaard said there was a lot of media speculation about what impact the global pandemic might have on the climate, greenhouse gas emissions and longer-term global warming.

“While in the short term, carbon dioxide emissions would go down as cars stay put and aircraft remain on the ground, “we expect the impact will be fairly short-lived,” Riishojgaard said.

“The pandemic will be over at some point and the world will start going back to work and with that, the CO2 emissions will pick up again, maybe or maybe not to quite the same level.”
