NASA: 2014 the warmest year on record
In this excellent video, NASA Goddard for Space Studies Director Dr. Gavin Schmidt refers to man’s use of greenhouse gases, especially carbon-based fuels such as oil and gasoline, which produce carbon dioxide (CO2), as the cause . . . or one of the causes . . . of the unprecedented rise in earth’s temperature. In fact, 2014, was the warmest year since 1880 when temperature records were first kept.
