How will the year 2020 be remembered? No doubt the headline event was the coronavirus pandemic, which shuttered schools, factories, and hospitality services, leading to a contraction of per capita income for ninety-five percent of the world’s economies.

Following the murder of George Floyd, similar rage at police brutality marked a turning point in the Black Lives Matter movement in the United States, which preceded a combative presidential election that denied Donald Trump a second term. And the world endured one of its hottest years on record, with surface temperatures reaching nearly one degree above the 141-year average as fires burned through Australia and the United States.
