Scott Pruitt, Administrator Of The Environmental Protection Agency, Claims Carbon Dioxide (CO2) Is Not “Primary Contributor” To Global Warming Despite Rising CO2 Concentrations And Rising Global Temperatures Since Late 19th Century

 In Environment   Last Updated: July 29, 2017

In an interview with CNBC on March 9, the new Administrator of the Environmental Protection Agency (EPA) stated:

I think that measuring with precision human activity on the climate is something very challenging to do and there’s tremendous disagreement about the degree of impact, so no, I would not agree that it’s a primary contributor to the global warming that we see.

However, NASA and NOAA scientists have concluded otherwise:

The planet’s average surface temperature has risen about 2.0 degrees Fahrenheit (1.1 degrees Celsius) since the late 19th century, a change driven largely by increased carbon dioxide and other human-made emissions into the atmosphere

The U.S. EPA website also states (as of March 11, 2017):

Since the Industrial Revolution began around 1750, human activities have contributed substantially to climate change by adding CO2 and other heat-trapping gases to the atmosphere.

CO2 levels in the air have risen dramatically since the late 19th century, from below 300 ppm (parts per million) to well over 400 ppm in the last 150 years.

2016 global average surface temperatures were also the warmest since modern record keeping began in 1880, with 16 of the 17 warmest years on record occurring since 2001.

C02 contributes to raising temperatures by absorbing heat from the sun’s rays, trapping this energy and radiating it within the Earth’s atmosphere.  More CO2 leads to more energy from the sun being trapped.
