Due to a precipitous rise in human-generated greenhouse gases, including carbon dioxide, the Earth's temperature has risen steadily since the industrial revolution. Since 1995, 11 of the 12 warmest years on record have occurred. Sources. Graphic: Robert A. Rohde, Global Warming ArtNational Geographic. Fact: National Geographic Magazine. |

Due to the Earth's convection system, warm air created by greenhouse gas production is pushed north to the Arctic. This process results in the Arctic warming at a significantly greater rate than the lower and middle latitudes where the vast majority of greenhouse gases are produced. This graphic depicts the trends in earth surface from 1976 through 2006 as compared to the the period from 1950 to 1975. Sources. Graphic generated by NASA using GISS Data.
