The increasing disconnection between the frequently-adjusted global surface temperature datasets and the accurate satellite measurement of the troposphere is casting further doubt on the unproven hypothesis that humans cause all or most climate change by burning fossil fuels. IPCC computer models predict a higher warming in the lower and mid-troposphere, but the latest Met Office retrospective adjustments produce 36% faster warming on the surface. “The lack of much tropospheric excess warming over surface warming suggests that changes in greenhouse gases are likely not a significant factor in current warming,” note scientists in a recently published Clintel report.
All the main surface temperature datasets have had large amounts of heating added to their retrospective records of late. Clintel notes that the recent update of the Met Office’s HadCRUT dataset showed 0.2°C more warming than its predecessor. In 2013, similar retrospective adjustments added considerable heating. As the Daily Sceptic reported last month, Professor Ole Humlum disclosed that since January 2008, the GISS database run by NASA increased its surface air temperature between 1910 to 2000 from 0.47°C to 0.67°C, a boost of 49% over this period. “Frequent and large corrections in a database unavoidably signal a fundamental uncertainty about the correct values,” noted Humlum.
