Does CO2 Cause Global Warming?

There’s no reason for you to doubt; the evidence is clear. There is a direct relationship between the amount of carbon dioxide (CO2) in the atmosphere and the average temperature on Earth. Increased carbon dioxide in the atmosphere is causing global warming, but don’t worry, you can help stop it.

CO2 causes global warming because as a greenhouse gas, it contributes to Earth’s natural Greenhouse Effect. [1]

There is a dangerous amount of CO2 in the atmosphere, much more than was present 150 years ago, and CO2 levels are still rising. [2] What is causing this potentially catastrophic increase in atmospheric CO2?

You Are Adding
CO2 to the Atmosphere

Coal, oil and natural gas release carbon dioxide when they are burned. Since the Industrial Revolution in the late 18th century, humans have been increasing their use of these so-called fossil fuels.

Ways your daily activities emit CO2

  • When you drive or fly, carbon is released into the atmosphere due to the use of fossil fuels.
  • Whenever you use electricity – turning on lights, watching television, or using a computer – coal is likely being burned to create power, and carbon is entering the atmosphere.
  • When you eat exotic foods that require long-distance transportation by truck or plane, carbon dioxide enters the atmosphere.
  • When you buy a newly-built home in a development built on land that was recently farm or forest, you reduce the ability of the plants that were growing on this land to take up excess carbon in the atmosphere.

So What’s the Good News?

So yes, the bad news is that CO2 does cause global warming and humans are responsible for elevated CO2 levels in the atmosphere.

Here’s the good news.
