Answer:
Human activities have increased the abundance of heat-trapping gases in the atmosphere. This increase is mostly due to burning fossil fuels, such as coal, oil, and natural gas. Carbon dioxide has increased from a pre-industrial level of 280 parts per million to more than 410 parts per million today. Most of the increase of carbon dioxide in the atmosphere has occurred since the late 1950s. In Earth’s distant past, it would take between 5,000 to 20,000 years to see the amount of change in carbon dioxide levels that humans have caused in just the last 60 years.
