Carbon dioxide (CO 2) is an important heattrapping (greenhouse) gas, which is released through human activities such as deforestation and burning fossil fuels, as well as natural processes such as respiration and volcanic eruptionsThe first graph shows atmospheric CO 2 levels measured at Mauna Loa Observatory, Hawaii, in recent years, with average seasonal cycleThis chart summarizes the global sources of greenhouse gases If there's one key takeaway from this chart, it's this No single piece of the global economy accounts for the lion's share of greenhouse gas emissions In other words, there's no main culprit, no magic bullet To solve the puzzle of climate change, each piece requires Power plants are the largest source of greenhouse gas pollution in the United States, accounting for more than onequarter of all domestic greenhouse gas emissions This map shows the total reported emissions from power plants by state in 19 and the number of reporting power plants in each state
