Read here and here. Sooo an AGW-biased "scientist" (affectionately known as a 'liar dude') has claimed that Arctic tundra hasn't burned in 10,000 years because there were no lightning strikes. Hmmmm.....
As it turns out, tundra areas of the Arctic have experienced warm weather, rain, thunder, lightning, malaria and even tundra fires over recorded history. Not a lot, but they do happen.
"Several thunderstorms on the north Siberia coast were recorded in the late 1700’s, and at least nine were observed on the northern coasts of Canada, Alaska or Siberia by explorers in the period 1815-1826...And where there’s thunderstorms there’s fire...Racine et al. (1985), reviewed wildfire records from 1956 through 1983 for the Noatak River watershed region which lies to the west of the North Slope and reported 79 fires during the 28-year study interval, the biggest of which burned nearly 200 square miles of “treeless thaw lake-studded portion of the Mission Lowlands tundra” and most, if not all of which were started by lighting...So there is historical documentation of both thunderstorms and wildfires in the Arctic including Alaska’s North Slope for many years into the past—and clearly previous to the past decade..."
This "scientist" then claimed that the CO2 released in the atmosphere had a huge impact on atmospheric CO2, which is even more bogus. (Note mauve color of below curve when tundra fire occurred - ahem...no impact on CO2 ppm.)
"Since CO2 is generally well-mixed in the atmosphere, Mauna Loa’s measurements should reflect anything unusual that is going on in the annual CO2 cycle. The period of the time when the 2007 Anaktuvuk River fire was burning is highlighted...Stare at/ponder/analyze Figure 2 all you want, but nothing unusual is going to pop out either during or immediately following the Anaktuvuk River fire. Simply put, the CO2 released by the “biggest wildfire ever recorded on the North Slope of Alaska” had an undetectable impact on the evolution of the global CO2 concentration."
As is the case with the majority of AGW-advocate scientists ('liar dudes') one literally cannot trust anything they say, claim or predict based on their "research." It is always tainted and/or biased with some Big Green message about global warming or climate change. And because the American public has caught onto this incessant green propaganda from biased scientists, the vast majority no longer believe them - hey, it's common knowledge they lie at least every 10,000 years seconds or so.
