claim: the satellite sensors show less warming in the lower troposphere ( approximately 10,000 feet above the earth’s surface ) than is reported by surface temperature readings.
evidence: The lowest air temperature ever directly measured on Earth was −89.2 °C ( −128.6 °F ) at Vostok Station in 1983, but satellites have used remote sensing to measure temperatures as low as −94.7 °C ( −138.5 °F ) in East Antarctica.
