Incompetence or Fraud in Alaska?

Alaska’s soils are taking far longer to freeze over as winter approaches than in previous decades, resulting in a surge in carbon dioxide emissions that could portend a much faster rate of global warming than scientists had previously estimated, according to new research.

Measurements of carbon dioxide levels taken from aircraft, satellites and on the ground show that the amount of CO2 emitted from Alaska’s frigid northern tundra increased by 70% between 1975 and 2015, in the period between October and December each year.

Researchers said warming temperatures and thawing soils were the likely cause of the increase in CO2 at a time of year when the upper layers of soil usually start freezing over as winter sets in.

In the Arctic summer, the upper level of soil, which sits above a vast sheet of permafrost that covers much of Alaska, thaws out and decomposing organic matter starts to produce CO2. From October, colder temperatures help freeze the soil again, locking up the CO2.

Alaska’s warming autumns and winters are altering this process. Whereas soils 40 years ago took about a month to completely freeze over, the process can now take three months or longer. In some places in the state, the soil is not freezing until January, particularly if there is a layer of insulating snow.

Autumn temperatures in Alaska have certainly increased since 1975.

But this is due to the switch in the PDO in the late 1970s, which brought warm water up from the Pacific.

Any half competent climatologist knows all about this.

But it is also apparent that recent Alaskan temperatures are similar to those in the 1930s to 50s, when the PDO was, as now, in warm phase.

So why do these junk scientists not tell us the truth?

Is it because they are simply incompetent?

Or is it deliberate fraud?

Why do CO2 lag behind temperature?

71% of the earth is covered by ocean, water is a 1000 times denser than air and the mass of the oceans are 360 times that of the atmosphere, small temperature changes in the oceans doesn’t only modulate air temperature, but it also affect the CO2 level according to Henry’s Law.

The reason it is called “Law” is because it has been “proven”!

“.. scientific laws describe phenomena that the scientific community has found to be provably true ..”

That means, the graph proves CO2 do not control temperature, that again proves (Man Made) Global Warming, now called “Climate Change” due to lack of … Warming is – again – debunked!
