Frequently Asked Questions about Climate Change Climate Change US EPA
The Global Monitoring Laboratory has measured carbon dioxide and other greenhouse gases for several decades at a globally distributed network of air sampling sites [Conway, 1994] Monthly comparison of CO2 levels measured by NOAA & Scripps at Mauna Loa. Monthly mean atmospheric carbon dioxide (CO₂) concentrations reached a record high of 426.91 parts per million (ppm) in June 2024.
How the World Passed a Carbon Threshold and Why It Matters Yale E360. In the book, CO2 Rising, Tyler Volk (2008) writes, "Data from. 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.
