What if GISS Holes were Pink?

What if GISS Holes were Pink?” Steven Goddard deliberately confuses temperature anomalies with absolute temperature in this post. Guess what: the Arctic is still colder than the tropics even though it has warmed more relatively. Steven knows this, but he enjoys pretending he doesn’t.

He also enjoys grumbling about the Goddard Institute for Space Studies’ global temperature model; not enough locations to be trusted! (How many would be enough?)

One thought on “What if GISS Holes were Pink?

  1. This is part VI(Jun15) in a series: I(May17), II(May18), III(May20), IV(May21), & V(Jun3).
    They all discuss section 7 of the GISS paper, “Current GISS Global Surface Temperature Analysis,” here.

    DMI……….The DMI temperature graph is for the area ‘north of the 80th northern parallel’. It excludes a large area of the Arctic Ocean, to our west above 70oN. And obiously this area isn’t as far north.

    “Arctic Ocean ice cover retreated faster last month than in any previous May since satellite monitoring began more than 30 years ago…” Montreal Gazette (June15,2010)

    So we have a visual measure of May warmth. Note that there was all this melting, without the DMI graph looking any hotter in May.

    “GISS CLAIM”……….”Steve returns to his (number-of-station) coverage straw-man argument. However, there is no ‘GISS claim that their divergence from HadCRUT over the last decade is due to better coverage.’ GISS only explains (in Section 7) why its EXTRAPOLATION of shore temperature anomalies is more representative than HadCRUT’s choice of the mean hemispheric temperature anomaly that results from its EXCLUSION of the Arctic Ocean.”

    “VISUALIZING WHIRLED PEAS”

    An Arctic GISS/infrared satellite comparison has been made. “…the temperature anomaly maps of Comiso(2006) have the largest positive temperature anomalies (several degrees Celsius) during the first decade of this century over the interior of Greenland and over the Arctic Ocean in regions where the sea ice cover has decreased…our analysis may understate warming in these regions…” (Section 7)

    “The aerial view of the actual GISS global anomalies would show (reddish) shore anomalies extending beyond the water’s edge. and covering the Arctic Ocean. The GISS paper discusses the reasonableness of such large scale extensions.”

    The globe that portrayed the actual final HadCRUT temperature anomalies would show the land anomaly coloring ending at the shoreline. And the Arctic Ocean would be colored with the color of the mean hemispheric temperature anomaly.

    And this would portray the Denier’s Dream. Polar Amplification disappears. The area of earth that has exhibited the highest temperature anomalies on earth, just goes away. Global average temperature anomalies immediately drop (by the amount shown in Steve’s ‘GISS minus HadCRUT’ graph)
