- Earth’s concentration of greenhouse gases and sea levels hit new highs in 2021, a U.S. government report said Wednesday, showing that climate change keeps surging ahead despite renewed efforts to curb emissions.
- The rise in greenhouse gas levels comes despite an easing of fossil fuel emissions the previous year as much of the global economy slowed sharply due to the COVID-19 pandemic.
- The less headline-grabbing average temperatures were in part due to La Nina, an occasional phenomenon in the Pacific that cools waters.
