Are humans contributing to global warming?
While there are natural sources of the primary greenhouse gases, human activities have without a doubt overloaded and changed the atmosphere. Ever since the Industrial Revolution, we’ve been steadily producing and releasing carbon dioxide and other heat-trapping gases into the atmosphere. In 2005, global atmospheric concentrations of carbon dioxide were 35% higher than they were before the Industrial Revolution.1Today, climate scientists, meteorologists and oceanographers are using high-tech tools and models to figure out just how much human activities have contributed to global warming. Using sophisticated computer programs and models, scientists can get a picture of how the Earth’s atmosphere and oceans respond to natural and human factors. Then they compare past climate patterns with these models to see which factors have contributed the most to global warming.You can learn more about how scientists measure climate from the Natural Resources Defense Council.

Technically you could say we’re contributing to it, but that’s pretty much where it ends for me. I also believe this is just one of the earth’s naturally occuring little episodes of change. However, to say that the amount of damage humans contribute is that significant is pretty arrogant. I think we contribute, but not enough to be devastating to the planet.
