Geology exam two study guide emissions have increased significantly (from 315 ppm co2 to around. 375 ppm co2: co2 content of gas bubbles in glacial ice have a longer record, since around the 1500s. The global geochemical cycle of carbon has both long-term geological and short-term human implications.
