Carbon Dioxide Passes 400 PPM Milestone, NOAA Finds

Climate scientists recognize this 400 ppm mark as a symbolic milestone, illustrating the rapid increase of human-caused CO2 emissions over the past century. Numerous other climate data, gleaned from ice cores, ocean sediment, and other sources show that this is the highest CO2 concentration in the air in all of modern human history, possibly as far… Read More
