Like the COVID-19 pandemic, climate change is a problem countries must work together to address or "all nations will feel the reverberations," the United Nations' climate chief warned on Wednesday.
The novel coronavirus has ignored national borders and "climate change respects them even less," Patricia Espinosa said in an online lecture for the London School of Economics.
"Many places that thought they would be completely free of the effects of climate change ... are already feeling it," said Espinosa, executive secretary of the U.N. Framework Convention on Climate Change.
