    Here you go olfraud. In this decade of ever rising global temps as manufactured by your high priests we have this proxy that shows quite conviningly that no warming has occured for quite a long time now.


    "Abstract

    In recent decades, significant changes have occurred in high-latitude areas, particularly to the cryosphere. Sea ice extent and thickness have declined. In land areas, glaciers and ice sheets are experiencing negative mass balance changes, and there is substantial regional snow cover variability. Subsurface changes are also occurring in northern soils. This study focuses on these changes in the soil thermal regime, specifically the seasonally frozen ground region of Eurasia. We use a database of soil temperatures at 423 stations and estimate the maximum annual soil freezing depth at the 387 sites located on seasonally frozen ground. Evaluating seasonal freeze depth at these sites for 1930–2000 reveals a statistically significant trend of −4.5 cm/decade and a net change of −31.9 cm. Interdecadal variability is also evident such that there was no trend until the late 1960s, after which seasonal freeze depths decreased significantly until the early 1990s. From that point forward, likely through at least 2008, no change is evident. These changes in the soil thermal regime are most closely linked with the freezing index, but also mean annual air temperatures and snow depth. Antecedent conditions from the previous warm season do not appear to play a large role in affecting the subsequent cold season's seasonal freeze depths. The strong decrease in seasonal freeze depths during the 1970s to 1990s was likely the result of strong atmospheric forcing from the North Atlantic Oscillation during that time period."

    So these psychics can say that there was no decrease in freeze depths in 2008 using data that ended in 2000. And CON$ bitch about missing global warming data. :cuckoo:

    Ummmm, this is just the abstract...if you actually get into the body of the study you will see how they derive their proxy data. Which is far more accurate then tree ring data that you've hung your hat on.

    No global warming for the last 20 years? Well, then, what caused all the sweat on my balls back in August? I'd say that was global warming or something like it.

    No, Walleyes, that paper shows no increase in the depth of permafrost melting for the last 20 years. No decrease, either.

    It does not show there has been no warming. That is a figment of your imagination. From the same publication;

    IOPscience - The response of the climate system to very high greenhouse gas emission scenarios

    Well informed decisions on climate policy necessitate simulation of the climate system for a sufficiently wide range of emissions scenarios. While recent literature has been devoted to low emissions futures, the potential for very high emissions has not been thoroughly explored. We specify two illustrative emissions scenarios that are significantly higher than the A1FI scenario, the highest scenario considered in past IPCC reports, and simulate them in a global climate model to investigate their climate change implications. Relative to the A1FI scenario, our highest scenario results in an additional 2 K of global mean warming above A1FI levels by 2100, a complete loss of arctic summer sea-ice by 2070 and an additional 43% sea level rise due to thermal expansion above A1FI levels by 2100. Regional maximum temperature increases from late 20th century values are 50–100% greater than A1FI increases, with some regions such as the Central US, the Tibetan plateau and Alaska showing a 300–400% increase above A1FI levels.

    West......... love ya bro, but this is just another thread about temperatures that is essentially irrelevant. The prevailing view is that nobody knows dick for certain, thus, the gigantic public yawn these days if the topic comes up.

    Of course, you miss the amusement value in claiming there has been no warming for 20 years using a study missing the data for the last 11 years! :rofl::lmao:

    Yes they use the same methods as you guys and you claim foul because they don't see the same things you do. I get it!:lol:
