September 2018 Global Surface (Land+Ocean) and Lower Troposphere Temperature Anomaly Update

By Bob Tisdale – Re-Blogged From WUWT

This post provides updates of the values for the three primary suppliers of global land+ocean surface temperature reconstructions—GISS through September 2018 and HADCRUT4 and NOAA NCEI (formerly NOAA NCDC) through August 2018—and of the two suppliers of satellite-based lower troposphere temperature composites (RSS and UAH) through September 2018. It also includes a few model-data comparisons.

This is simply an update, but it includes a good amount of background information for those new to the datasets. Because it is an update, there is no overview or summary for this post. There are, however, simple monthly summaries for the individual datasets. So for those familiar with the datasets, simply fast-forward to the graphs and read the summaries under the headings of “Update”.

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:

Memo to Paris: Don’t Base Policy on Overblown Prediction

Halfway to 2°C – halfway to hell on Earth or just a number?

By Christopher Monckton of Brenchley – Re-Blogged From WattsUpWithThat

The Met Office is at it again. Just in time for Paris, in a stunt co-ordinated with the unspeakable BBC, it issued a characteristically mendacious press release saying that global mean surface temperature was about to exceed 1 C° above the mean for the reference period 1850-1900 for the first time.

And this, said the excitable David Shukman, the BBC’s pseudoscience editor on the ten o’clock news, was the halfway milestone to 2 C°, which, he said, was generally accepted to be the threshold of dangerous global warming.

Here, in pictures, is the answer to the Met Office’s hysterical press release.
