How stimulus dollars are spent will affect emissions for decades
The COVID-19 pandemic and subsequent lockdowns have led to a record crash in emissions. But it will be emission levels during the recovery–in the months and years after the pandemic recedes–that matter most for how global warming plays out, according to a new Nature commentary from researchers at the University of California San Diego. While the skies have […]
