Top chart: Earth's climate has cycled between ice ages and warm interglacial periods, with each cycle taking tens of thousands of years or more. Middle chart: Global average temperature was in a cooling trend for thousands of years before fossil fuel based industrialization. Since then, it has increased about a full 1°C—in a time period less ...

The resulting temperature data series actually used to make this graph, and their five-interval (100-year) moving average data series, are provided in the expandable text below. The same dataset, averaged within each millennium to form series of 800 data points, was used to form 800,000-year chart in the top panel of File:800,000-, 2,000-, 139 ...
