Climate Science Double-Speak

By Kip Hansen – Re-Blogged From http://www.WattsUpWithThat.com

A quick note for the amusement of the bored but curious.

While in search of something else, I ran across this enlightening page from the folks at UCAR/NCAR [The University Corporation for Atmospheric Research/The National Center for Atmospheric Research — see pdf here for more information]:

What is the average global temperature now?

Australia Weather Bureau Caught Tampering With Climate Numbers

By Chris White – Re-Blogged From http://www.WattsUpWithThat.com

Australian scientists at the Bureau of Meteorology (BOM) ordered a review of temperature recording instruments after the government agency was caught tampering with temperature logs in several locations.

Agency officials admit that the problem with instruments recording low temperatures likely happened in several locations throughout Australia, but they refuse to admit to manipulating temperature readings. The BOM located missing logs in Goulburn and the Snow Mountains, both of which are in New South Wales.

Debunking Inside Climate’s “5 Shades of Climate Denial”

By David Middleton – Re-Blogged From http://www.WattsUpWithThat.com

Sometimes, words fail me in describing the absolute disregard of the placement of NOAA official climate monitoring sites. For example, this one in Clarinda, Iowa submitted by surfacestations volunteer Eric Gamberg:

 

The MMTS temperature sensor is the short pole next to the half pickup truck.

For those of you that don’t know, this station is located at the wastewater treatment plant there. I’ve written many times about the placement of stations at WWTP’s being a bad idea due to the localized heat bubble that is created due to all the effluent coming though. The effect is especially noticeable in winter. Often you’ll see steam/water vapor in the air around these sites in winter, and more than one COOP observer has told our volunteers that snow sometimes does not stick to the ground at WWTP’s.

Climate Models and Climate Reality Vary Greatly

By Anthony Watts – Re-Blogged From http://www.WattsUpWithThat.com

A new paper has been published in Geophysical Research Letters that shows once again, that climate models and reality significantly vary. It confirms what Dr. John Christy has been saying (see figure below). The paper also references Dr. Judith Curry and her work.


Pronounced differences between observed and CMIP5-simulated multidecadal climate variability in the twentieth century

Plain Language Summary

Global and regional warming trends over the course of the twentieth century have been nonuniform, with decadal and longer periods of faster or slower warming, or even cooling. Here we show that state-of-the-art global models used to predict climate fail to adequately reproduce such multidecadal climate variations. In particular, the models underestimate the magnitude of the observed variability and misrepresent its spatial pattern. Therefore, our ability to interpret the observed climate change using these models is limited.

Abstract

Identification and dynamical attribution of multidecadal climate undulations to either variations in external forcings or to internal sources is one of the most important topics of modern climate science, especially in conjunction with the issue of human-induced global warming. Here we utilize ensembles of twentieth century climate simulations to isolate the forced signal and residual internal variability in a network of observed and modeled climate indices. The observed internal variability so estimated exhibits a pronounced multidecadal mode with a distinctive spatiotemporal signature, which is altogether absent in model simulations. This single mode explains a major fraction of model-data differences over the entire climate index network considered; it may reflect either biases in the models’ forced response or models’ lack
of requisite internal dynamics, or a combination of both.

Climatic Temperature

By Leo Goldstein – Re-Blogged From http://www.WattsUpWithThat.com

When something pretending to be a science cannot adequately define a quantity for its central subject, this something is inarguably a pseudo-science. This is certainly the case in the self-professed “climate science.” It proposes the hypothesis of a dangerously warming climate, but does it define a meaningful climatic temperature that can be robustly calculated from the observations at the current time? To the extent that it does define climatic temperature (meaningfully or not), does it pay much attention to this quantity? The answer to both these questions is a resounding NO.

Averages: A Primer

As both the word and the concept “average” are subject to a great deal of confusion and misunderstanding in the general public and both word and concept have seen an overwhelming amount of “loose usage” even in scientific circles, not excluding peer-reviewed journal articles and scientific press releases,  let’s have a quick primer (correctly pronounced “primer”), or refresher,  on averages (the cognizanti can skip this bit and jump directly  to  Fruit Salad).
