Current Ppm Of Co2 In Atmosphere 2025 Current. CO2 reached 420 ppm in the atmosphere Latin American VC 4), which is a decrease of Earth's albedo (reflectivity) by 0.4% (1.4/340).9 This reduced albedo is equivalent to a sudden increase of atmospheric CO2 from 420 to 530 ppm. Global atmospheric carbon dioxide has risen more than 50 percent since 1800, and it hit a new high of 422.03 parts per million in 2024.
