"Near the end of 2020, as the covid-19 pandemic continued to rage, a few climate scientists and energy experts made a prediction. They estimated that emissions from fossil fuels — which had just plummeted thanks to the global pandemic — might never again reach the heights of 2019. Perhaps, they speculated, after over a century of ever more carbon dioxide flowing into the atmosphere, the world had finally reached “peak” emissions.
They were wrong.
According to a report released last month by the Global Carbon Project, carbon emissions from fossil fuels in 2022 are expected to reach 37.5 billion tons of carbon dioxide, the highest ever recorded. That means that despite the continued fallout from the coronavirus pandemic — which caused emissions to drop by over 5 percent in 2020 — CO2 emissions are back and stronger than ever.
Scientists have reacted with dismay. For years before the pandemic, emissions appeared to be leveling off — sparking hope that the world was finally reaching the moment when emissions would start to come down. Then in 2020, “Covid came, there was a huge drop in emissions — and I guess we got a little overexcited,” said Glen Peters, a climate scientist at the Center for International Climate Research in Oslo."
