From the Solar Eclipse to Global Heating, Dr. Peter Kalmus on the Importance of Science
Three of the most significant greenhouse gases contributing to global heating — carbon dioxide, methane and nitrous oxide — reached new record highs again last year, according to the U.S. National Oceanic and Atmospheric Administration. Global CO2 levels are now over 50% higher than they were before mass industrialization, due to the burning of fossil fuels, deforestation and livestock agriculture.
