Nova – not Hot, not Angry, not Surface Temps

Joanne Nova still seems bitter about the fact that Australia had its HOTTEST EVER SUMMER and has tried once again to discredit the temperature record after climate scientists found that humans are increasing the chances of such an event. Nova is repeating an earlier myth so her mistake also repeated (learning can be difficult for some climate denialists).

The UAH temperatures she plots in the graph are atmospheric temperatures, which is not going to be the same as surface temperatures (I am also dubious about how they restrict UAH temperatures to just Australia land). Surface temperatures, as measured by the BOM and reported to the public on a daily basis are NOT the same as the temperature of the atmosphere. This is demonstrated clearly in the graph below.

Over short timeframes, surface temps and atmospheric temps can have large differences.

Since 1979, all surface and atmospheric temperatures show very similar trends.

    I found it interesting that Joanne Nova and Eddy Aruda both claimed the UAH data was for the surface and could be directly cmpared against the BOM measurement.

    Even after I had questioned them several times they still clung to their belieif rather than actually investigate and realise their mistake.

    I am surprise Nova allowed my final post to eventually be released from moderation (all my posts go immediately into “awaiting moderation”). The final outcome: http://joannenova.com.au/2013/06/australias-angry-hot-summer-was-hot-angry-hype-satellites-show-it-was-average/#comment-1292368

    Let’s see how they respond now after I have pointed out their data is in fact for the Lower Troposphere (T2LT), not for the Surface.

    Even Nova’s friends say the file represents the Lower Troposphere and specifically mention the file Ken uses.

    http://www.co2science.org/data/temperatures/msu_des.php

    Here’s their words:

    “In contrast to the GHCN and Jones et al. temperature data sets that represent temperatures at about 2 meters above the earth’s surface, the MSU data set represent the temperatures of a layer of the atmosphere that extends from the surface to approximately 8 kilometers (5 miles) above the surface.”

    Roger Pieke also mentions this file specifically and that it represents the Lower Troposphere.

    In his words:

    “The satellite-based instruments measure the temperature of the atmosphere from the surface up to an altitude of about eight kilometers above sea level.”

    Eddy and Nova stuffed up big time.
