World bounces back to nearly 2019 carbon pollution levels

The dramatic drop in carbon dioxide emissions from the pandemic lockdown has pretty much disappeared in a puff of coal-fired smoke, much of it from China, a new scientific study found.

A group of scientists who track heat-trapping gases that cause climate change said the first nine months of this year put emissions a tad under 2019 levels. They estimate that in 2021 the world will have spewed 36.4 billion metric tons of carbon dioxide, compared to 36.7 billion metric tons two years ago.
