The salient facts are these. First, the accepted global average temperature statistics used by the Intergovernmental Panel on Climate Change show that no ground-based warming has occurred since 1998. Oddly, this eight-year-long temperature stasis has occurred despite an increase over the same period of 15 parts per million (or 4 per cent) in atmospheric CO2.
Second, lower atmosphere satellite-based temperature measurements, if corrected for non-greenhouse influences such as El Nino events and large volcanic eruptions, show little if any global warming since 1979, a period over which atmospheric CO2 has increased by 55 ppm (17 per cent).
Third, there are strong indications from solar studies that Earth’s current temperature stasis will be followed by climatic cooling over the next few decades.
