The Amazon rainforest is emitting more carbon dioxide than it absorbs, according to a new pollution report — the opposite of what is supposed to happen.
Elsewhere in the world, air pollution levels spiked in 2021 after dropping in 2020 due to COVID-related lockdowns, according to the annual World Air Quality Report released by pollution tracking company IQAir.
Analyzing measurements from air monitoring stations in 6,475 cities around the world, IQAir found that just 3% of cities — and not a single country overall — had met the annual air quality guidelines spelled out by the World Health Organization to protect public health.
