Still Fuming?

One might have hoped that the reductions in travel and other activities, following the Covid-19 lockdowns seen in many parts of the world, would have led to a reduction in the level of carbon dioxide in the atmosphere. Carbon dioxide is, of course, a major 'greenhouse gas' and a primary  cause of climate change. Unfortunately, the readings taken at the observatory at the peak of Moana Loa on Hawaii's Big Island (a place very distant from emissions) are continuing to rise to new record levels (https://www.theguardian.com/environment/2020/jun/04/atmospheric-co2-levels-rise-sharply-despite-covid-19-lockdowns). Reversing climate change may comparable to getting a large oil tanker to change course.
