Emissions may be down, but carbon dioxide still piles up relentlessly in the atmosphere. It’s more important than ever to find climate change solutions, experts say.
In May, the concentration of carbon dioxide in the atmosphere was the highest ever recorded in human history and likely higher than at any point in the last three million years.
That record was broken in the midst of the coronavirus pandemic, even though the health crisis has driven one of the largest, most dramatic drops in CO2 emissions ever recorded.
