The Evidence Keeps Piling Up: Iceland Is Not Cooperating With The ‘Global Warming’ Agenda

If decadal- and century-scale glacier advance and retreat is strongly indicative of a region’s climate, glacier behavior in Iceland saps the narrative that says anthropogenic CO2 is a climate driver.

Per a new study, many of the northern Icelandic glaciers in existence today had “disappeared” from about 10,000 to 6,000 years ago. At the time, atmospheric CO2 levels allegedly lingered within the 255 to 270 ppm “safe” range.

“During the Holocene Thermal Maximum (HTM) (10-6 ka) the debris-free glaciers, due to their high climate sensitivity, have most probably disappeared in central Iceland…and the nearby Langjökull and Drangajökull ice caps.”

In the last 10,000 years Iceland’s highest levels of glacier and sea ice advance, coinciding with the Holocene’s coldest climates, occurred from about 700 to 100 years ago. This period is often referred to as the Little Ice Age (LIA).

But while the ice retreated in the 1920s to 1940s, the ice once again advanced from the 1970s to 1990s – just as human CO2 emissions rates were doubling from ~3 GtC/year to 6 GtC/year.

The “favorable climatic conditions” triggering a glacial advance “has occurred in Héðinsdalsjökull cirque at least twice, namely during the LIA maximum and since the mid-1970s to mid-1990s.”

Another recent study, Geirsdóttir et al. (2020), suggests Iceland’s climate was 3-4°C warmer than modern during the Holocene Thermal Maximum. The coldest temperatures of the last 10,000 years – as well as the peak advance of glaciers and regional sea ice – were realized in the 1800s. There has only been a modest ice retreat since then.

A temperature record for North Iceland (Fernández-Fernández et al., 2017) suggests there has been no net warming in this region for about the last 90 years.

    “… glacier behavior in Iceland saps the narrative that says anthropogenic CO2 is a climate driver”.
    Not necessarily, it does refute the notion of CO2 as the overriding climate driver.

    Time to crack down on Iceland. Make them toe the Global Warming line.

    How can CO2 be so abundant in the atmosphere that it is causing a greenhouse effect? Gases are weighed according to their “Vapor Density.”

    The relative weight of a gas or vapor compared to air, which has an arbitrary value of one. If a gas has a vapor density of less than one it will generally rise in air. If the vapor density is greater than one the gas will generally sink in air. And this: At standard temperature and pressure, the density of carbon dioxide is around 1.98 kg/m3, about 1.5 times that of air.

    CO2 has a vapor density of 1.53, which means its quite a bit heavier than air. So the CO2 that is generated on the planet’s surface stays down low & the CO2 produced in the skies will drift down to the planet, so where’s the greenhouse effect coming from, since all those cow farts Mr Know-it-all Gates worries bout will stay on the Earth’s surface?

    Or did they rewrite the laws of chemistry like the did the laws of Thermo-Dynamics on 9/11?
