But these relatively small and temporary changes should not be mistaken for the COVID-19 pandemic actually helping to fix climate change. Quite the contrary: the pandemic that made the world stop offers a glimpse of the deep changes in lifestyles and economic structures that we need to implement if we are to effectively mitigate the worst of climate change.
The short-term effects are not in doubt. A new study in Nature Climate Change led by scientists from the University of East Anglia and Stanford has found that daily global CO₂ emissions in early April 2020 were down 17% compared to the mean level of emissions in 2019.
This finding backs up an earlier report from the International Energy Agency (IEA) which found that CO₂ emissions from fossil fuel combustion —globally, the main source of greenhouse gas emissions—in the first three months of 2020 were 5% lower compared to the same period last year.
But the short-term and long-term effects […]
