CO2 Levels are Higher Than They’ve Been in 800,000 Years Atmospheric CO2 has increased by more than 100 parts per million since the Industrial Revolution in the mid-1700s, when humans began burning fossil fuels like coal and oil. Human activity has increased CO2 to levels not seen in the...
Since the industrial revolution began, the atmospheric abundance of key greenhouse gases have increased substantially.
Scientists say higher CO2 levels strengthen the “greenhouse effect” and could increase the Earth’s temperature. In fact CO2 levels have risen by 30 percent since the Industrial Revolution of the 18th and 19th centuries.Over the past three years satellite measurements have shown a sea level ...
