The Abject Failure of Official Global-Warming Predictions

By Monckton of Brenchley – Re-Blogged From http://www.WattsUpWithThat.com

The IPCC published its First Assessment Report a quarter of a century ago, in 1990. The Second Assessment Report came out 20 years ago, the Third 15 years ago. Even 15 years is enough to test whether the models’ predictions have proven prophetic. In 2008, NOAA’s report on the State of the Global Climate, published as a supplement to the Bulletin of the American Meteorological Society, said: “The simulations rule out (at the 95% level) zero trends for intervals of 15 yr or more, suggesting that an observed absence of warming of this duration is needed to create a discrepancy with the expected present-day warming rate.”

To the continuing embarrassment of the profiteers of doom, the least-squares linear-regression trends on Dr Roy Spencer’s UAH satellite dataset shows no global warming at all for 18 years 6 months, despite a continuing (and gently accelerating) increase in atmospheric CO2 concentration, shown on the graph as a gray trace:

July 2015 Global Surface (Land+Ocean) and Lower Troposphere Temperature Anomaly & Model-Data Difference Update

By Bob Tisdale – Re-Blogged From http://www.WattsUpWithThat.com

This post provides an update of the values for the three primary suppliers of global land+ocean surface temperature reconstructions—GISS through July 2015 and HADCRUT4 and NCEI (formerly NCDC) through June 2015—and of the two suppliers of satellite-based lower troposphere temperature composites (RSS and UAH) through July 2015.  It also includes a model-data comparison.
