Climate change: About that massive ice melt … yeah, never mind
While “the science is settled” and name calling are about all the climate alarmists have in their mostly empty rebuttal quiver, real science continues to destroy their ‘settled science’.
I’m sure you remember all the doom and gloom emanating from the claims that massive amounts of ice was melting and would raise sea levels to catastrophic heights, don’t you?
Yeah, well, it appears – shock of shocks – that those making those claims didn’t use science at all. They apparently just kind of made it up if the American Geophysical Union’s latest research is to be believed:
"Previous ocean models … have predicted temperatures and melt rates that are too high, suggesting a significant mass loss in this region that is actually not taking place," says Tore Hattermann of the Norwegian Polar Institute, member of a team which has obtained two years’ worth of direct measurements below the massive Fimbul Ice Shelf in eastern Antarctica – the first ever to be taken.
[…]
It turns out that past studies, which were based on computer models without any direct data for comparison or guidance, overestimate the water temperatures and extent of melting beneath the Fimbul Ice Shelf. This has led to the misconception, Hattermann said, that the ice shelf is losing mass at a faster rate than it is gaining mass, leading to an overall loss of mass.
The team’s results show that water temperatures are far lower than computer models predicted …
In fact:
Overall, according to the team, their field data shows "steady state mass balance" on the eastern Antarctic coasts – ie, that no ice is being lost from the massive shelves there. The research is published in the journal Geophysical Research Letters.
You don’t say? But, but “climate deniers are the same as Holocaust deniers”, “the sciences is settled”, “consensus”, the “vast majority of the world’s scientists agree”, “IPCC”, yatta, yatta, yatta.
Again we see the so-called science wasn’t based on science at all – it was based on computer models “without any direct data for comparison or guidance” which then naturally got the results the “scientists” were looking for.
I’d love to say I’m stunned, but I’m not.
We’ve known this was happening for how long now? It’s just that the evidence just keeps coming out, doesn’t it.
If you’re still an alarmist that believes in the “science” that was put out in the IPCC report and an “Inconvenient Truth”, then it isn’t science we’re talking about anymore – it’s religion.

Climate Alarmists claim victory with an old and discredited data set on temperature
Kevin Drum is all excited. Writing at Mother Jones he tells us:
But Muller’s congressional testimony last March didn’t go according to plan. He told them a preliminary analysis suggested that the three main climate models in use today—each of which uses a different estimating technique, and each of which has potential flaws—are all pretty accurate: Global temperatures have gone up considerably over the past century, and the increase has accelerated over the past few decades. Yesterday, BEST confirmed these results and others in its first set of published papers about land temperatures.
Oh boy … confirmation. “I told you so” time. Finally got those deniers pinned to the wall.
Yeah, not really. Anthony Watts cites a paragraph from the Economist and then explains why this isn’t anything new:
Economist: “There are three compilations of mean global temperatures, each one based on readings from thousands of thermometers, kept in weather stations and aboard ships, going back over 150 years. Two are American, provided by NASA and the National Oceanic and Atmospheric Administration (NOAA), one is a collaboration between Britain’s Met Office and the University of East Anglia’s Climate Research Unit (known as Hadley CRU). And all suggest a similar pattern of warming: amounting to about 0.9°C over land in the past half century.”
The nearly identical trends is no surprise as they draw from mostly the same raw data!
Same old data (that’s been questioned quite often given the location of many of the temperature stations in parking lots, fudging of numbers, cherry picking, etc), “new” trend analysis, same results.
Watts concludes:
The new Muller et al study, therefore, has a very major unanswered question. I have asked it on Judy’s [Curry] weblog since she is a co-author of these studies [and Muller never replied to my request to answer this question].
“Hi Judy – I encourage you to document how much overlap there is in Muller’s analysis with the locations used by GISS, NCDC and CRU. In our paper
Pielke Sr., R.A., C. Davey, D. Niyogi, S. Fall, J. Steinweg-Woods, K. Hubbard, X. Lin, M. Cai, Y.-K. Lim, H. Li, J. Nielsen-Gammon, K. Gallo, R. Hale, R. Mahmood, S. Foster, R.T. McNider, and P. Blanken, 2007: Unresolved issues with the assessment of multi-decadal global land surface temperature trends. J. Geophys. Res., 112, D24S08, doi:10.1029/2006JD008229.http://pielkeclimatesci.files.wordpress.com/2009/10/r-321.pdf
we reported that
“The raw surface temperature data from which all of the different global surface temperature trend analyses are derived are essentially the same. The best estimate that has been reported is that 90–95% of the raw data in each of the analyses is the same (P. Jones, personal communication, 2003).”
Unless, Muller pulls from a significantly different set of raw data, it is no surprise that his trends are the same.
More deception cloaked as “new” science from the alarmist crowd.
What a surprise indeed.
