Prognosis 'Poor'?

There has been lots of optimistic comment about how the Covid-19 pandemic has reduced atmospheric polluting events, by largely closing down air travel and reducing industrial activity. In spite of this, the World Meteorological Organization (WMO) has noted that the upward trend of carbon dioxide in the air in 2020, has continued its inexorable rise (https://www.theguardian.com/environment/2020/nov/23/climate-crisis-co2-hits-new-record-despite-covid-19-lockdowns). Measurements are routinely taken on remote mountain tops on Hawaii's Big Island and in Tasmania. WMO describe any pandemic-related decline in this 'greenhouse gas', as being a 'tiny blip' and 'less than the natural fluctuation' that is generally seen. And people can't wait to get back on planes and to 'restart' their economies! The omens don't look good.
