David Rosnick, an Economist at the Center for Economic and Policy Research, uses the Global Change Assessment Model to estimate the effects of population growth on the change in global average temperature by 2100.
“There are many warnings of ‘demographic time bombs’ due to population declines in countries like Japan and even China,” Rosnick said. “But lower population growth actually has many economic benefits; one of the most important is that it reduces the rate of global climate change.”
