Evidence from throughout the world shows that the planet was relatively warm 1,000 years ago during the Medieval Warm Period and relatively cold 500 years ago during the Little Ice Age. When the 1°C (1.8°F) of global warming of the past 100 years is considered in the context of climate variability of the last 1,000 years, the recent warming looks quite natural and nothing out of the ordinary. In 2001, the United Nations Intergovernmental Panel on Climate Change prominently featured an important graph of northern hemispheric temperatures over the past 1,000 years, and the plot resembled a hockey stick. This same graph was recently highlighted in testimony to the North Carolina Legislative Commission on Climate Change.
