    You can keep saying what you're saying, but maybe one day it will sink in
    that the adjustments seem to be warranted. The skeptics have proven time
    and again that they are.
    You can drag out the changes made to climate sensitivity if you want but
    the changes to various data nearly without fail favors one point of view.
    Are the changes warranted? Of course they are. The changes that should
    have been made that went the other way because they were warranted were
    ignored and never made. Do I know what those are? No of course I don't.
    I can only guess that they are there. I can only observe the pattern and
    the pattern is there. You don't want to acknowledge the pattern. You want
    to pretend that the pattern isn't there.

    See above for what's a knicker twister.

    Summary: The global warming we said was not happening, and then had paused? Well, it was not really happening all along!

    Thanks for nothing. Your shiny new graph is well known and accounted for in the temperature record.

    Now that the 15-year pause and the Met Office changes having proved ephemeral arguments, the men who "agreed the world was warming" are now like the dog back eating its vomit: it's all made up, and those record heatwaves, bushfires, storms and droughts are not happening.

    Basically, after blinking in the sunlight for a few minutes, the lads are back in fantasy-land.

    Thanks for the evidence, Steve. Your "pattern" is an artifact of your political playbook. As barry says, the changes are trivial, your politics makes you want to thinks its important.

    Ok the debate about whether temperatures have increased over the last 15 years or not is now officially over.

    James Hansen has come out on the record with the following:

    The five-year mean global temperature has been flat for the last decade, which we interpret as a combination of natural variability and a slow down in the growth rate of net climate forcing.
    Anyone with an ounce of mathematical knowledge will know that the only way for a 5 year trailing average to remain flat for 10 years is if the data is flat for 15.

    Case closed. No warming for the last 15 years. So says James Hansen.

    All looks fishy to the fishy eye.

    barry has shown the effects are trivial and so not affect warming rates. Dr Spencer had to be shamed into adjusting for orbital decay, plus his coding errors, and no one ever mentions that - the biggest data scandal in climate science.

    For some time, the UAH satellite data's chief significance was that they appeared to contradict a wide range of surface temperature data measurements and analyses showing warming. In 1998 the UAH data showed a cooling of 0.05K per decade (at 3.5 km - mid to low troposphere). Wentz & Schabel at RSS in their 1998 paper showed this (along with other discrepancies) was due to the orbital decay of the NOAA satellites.[6] Once the orbital changes had been allowed for the data showed a 0.07K per decade increase in temperature at this level of the atmosphere.

    As usual, scared to give the link so that we can go and see this is just spin. So now the guy you regularly claim is faking the data is talking the gospel truth. Well, what next? You will be voting for Al Gore.

    Actually, I think he is just agreeing with me, as I showed yesterday:



    The rate of change of warming may have slowed, but as I pointed out, that is not a "pause" or a "no warming" event. The earth climate system is not at equilibrium - therefore it must warm up long term.

    James Hansen is spinning?

    Is that quote attributable to him or not? Did he write that the 5 year mean temperature has been flat for a decade or did he not?

    Here's the Hansen story Trainwreck mangled.

    And while the moving five-year mean temperature for the globe has been flat for a decade, that doesn't mean global warming has stalled, according to Hansen, a longtime advocate for action to curb greenhouse gas emissions that contribute to climate change.

    "APPARENT STANDSTILL" IN WARMING?

    Noting that each of the last three decades has been warmer than the one that preceded it, he said an "apparent standstill" in global warming could be due to weak El Nino patterns, which would normally heat up things in many places, and strong La Nina patterns, which have a corresponding cooling effect.
