Carbon dioxide emissions in 2020 will not reach record levels. The main greenhouse gas was released into the atmosphere to fuel global warming during April at a rate 17% lower than during the same month in 2019. That means a drop of 17 million tonnes of the gas every day. The news is unlikely to be welcomed by climate scientists, environmental campaigners and governments interested in reducing the hazard of climate catastrophe. None of the fall in emissions was because of determined policies to reduce the rate of emissions and therefore the speed of climate change. Emission levels have fallen to a level last observed in 2006. This is explained entirely by a series of simultaneous multinational lockdowns and economic slowdown as a consequence of an unexpected, and unprecedented, pandemic of a novel coronavirus that at the time of writing had worldwide claimed more than 330,000 lives. The sudden slowdown in car journeys as businesses closed, workers were laid off and schoolchildren stayed at home accounted for almost half the decrease, according to a team of international scientists reporting in the journal Nature Climate Change. Foreign travel fell, airports stayed silent, to account for a 10% fall. For the extent of a northern hemisphere spring, people had a chance to experience a world in which atmospheric pollution of every kind was reduced, fossil fuel consumption dropped, and people walked or cycled or simply stayed at home.
