2017: 150 Graphs, 122 Scientific Papers

In the last 12 months, 150 graphs from 122 peer-reviewed scientific papers have been published that undermine the popularized conception of a slowly cooling Earth temperature history followed by a dramatic hockey-stick-shaped uptick, or an especially unusual global-scale warming during modern times.

Yes, some regions of the Earth have been warming in recent decades or at some point in the last 100 years.

Some regions have been cooling for decades at a time.

And many regions have shown no significant net changes or trends in either direction relative to the last few hundred to thousands of years.

Succinctly, then, scientists publishing in peer-reviewed journals have increasingly affirmed that there is nothing historically unprecedented or remarkable about today’s climate when viewed in the context of long-term natural variability.

The following (partial) list has been organized by geographical region.

    Kenneth, another fantastic compilation. I have no idea how you have the time or energy to produce these reports but please keep it up.

    I am generally just a reader (lurker) on this site but I always enjoy your posts. I am sure there are many hundreds just like me enjoying your contributions while doing our best to ignore the ramblings of trolls like Seb…….

    Happy New Year to you and yours.

    […] would rely on a model where the independent variable can change by 33% and have no impact on the dependent variable? That isn’t science, that is […]

    Meanwhile the “Unprecedented Recent Warmth” industry rolls along, such as in this recent effort by Briffa et al:


    Is it just me, or does dendroclimatology have zero credibility? It seems to be so full of magic potions and secret incantations, and the outputs seem indistinguishable from random noise, with only certain examples getting any publicity.

  4. RAH

    You know so much of climate science is expressed in charts and graphs. But at least for me, when there is a historical record that runs counter to the charge or graph being presented then I go with the history. I trust the contemporary accounts of events more than I do any reconstruction or even thermometer data when that data is just for a very confined area of a regional or hemispherical or global climate event.

    I see these various temperature charts that seem to minimize the MWP and LIA and they just don’t add up with what was written about the weather and conditions at the time.

    1. mikewaite

      From my recent reading I would agree with you RAH. I have been collecting information about recent archaeology in SW Greenland , the Norse settlements , for a proposed talk to a local archaeology/history group. (Vikings are always popular subjects).
      Much of the recent archaeology is a rescue attempt to recover organic remains threatened by permafrost thawing.
      It is obvious that the ground in which people were buried, or their wste deposited in the 11th to 14th cent was not frozen , nor were their hay fields , but they are now only just emerging from the LIA freezing .
      The attempts to diminish the MWP/MCA by adjustment of proxy results thus run counter to the physical evidence. I know which I am inclined to believe.

    I join with others above in saying thank you to both Richard and Pierre for this down to earth site keeping us informed in a factual way
    Cheers for 2018

    NON-Global Warming

    Seems you mean
    Global Non-Warming

    1. AndyG55

      Maybe not.

      There has been some highly beneficial regional warming linked to solar and ocean cycles.. (mostly in colder NH places that could use some warming)

      But the warming has definitely been NON-global.
