2020 is predicted to be the hottest year in recorded history, according to a new report by the US National Oceanic and Atmospheric Administration. Scientists say that despite reductions in air pollution across the world, owing to the Covid-19 lockdown, temperatures will continue to rise. This is due to the accumulated green house gases that are already present in the atmosphere. There is a 75% chance that 2020 will surpass 2016 as the hottest year on record, says the report. Scientists urge nations to use the Covid-19 crisis as a catalyst to promote more sustainable and energy-efficient means of transportation and energy production.
