Crazy Weather and the Arctic Meltdown: Dr Jennifer Francis

My point of contention here is that the melting is coming from a warmer land mass from underneath.

as well as a warmer atmosphere.

Az,
The issue for you is that warming from below may be contributing as much or more than atmospheric warming caused by the burning of fossil fuels (i.e. CO2  pollution).

I wish that was true. Overwhelmingly, the culprit here is CO2 pollution. CO2 pollution is an existential threat to humanity and several thousand other macroscopic species in our biosphere. We are not talking about a 60/40 split in warming action. We are talking about over 99% CO2 caused warming versus less than 1% warming from below. 

I know you don't agree with that, but that is what the scientific consensus has concluded. I just ask you to look at the evidence below.

I am sure you remember the fossil fuel industry propaganda that a "pause" in global warming had occurred for about ten years after the year 2000.

A statistical analysis of the warming in the atmosphere was done for the last several decades in order to extract non-human causative factors. The purpose of that exercise was to see exactly what the trend was sans natural effects like volcanic activity (e. g. Pinatubo eruption caused temporary cooling) and the geothermal warming from beneath the land masses that you are concerned with.

When they did that, the alleged "plateau" where the "global warming stopped" for about a decade after 2000 (that the fossil fuel industry pushed all over the media and Congress - Snowleopard  and MKing pushed it here) was shown to be a cherry picked fraud.

Furthermore, with the natural background effects stripped out, the atmospheric increased warming effects from CO2 pollution stood out glaringly as the exclusive cause of the INCREASE in oceanic and atmospheric warming.

WHY?

Because the others remained in a range of variability with no significant up or down trend.

Dr. Francis shows a bar chart produced by the insurance industry of the total infrastructure destruction in human civilization over several decades. This is used by actuaries to determine risk and price the premiums for property insurance.


Geophysical events (Earthquakes, tsunamis, volcanic eruptions, etc.) certainly are a huge concern for insurance companies. But the bottom line is that their MAIN concern is the atmospheric caused extreme weather events.

WHY?

Because atmospheric caused extreme weather events, unlike the geophysical caused extreme events, are increasing. 

Persistent weather patterns are THE cause of the increase in extreme weather events.

The following graphic shows various sites in Alaska where evidence of permafrost warming, due to a warmer atmosphere, not warming from below (those areas are not volcanic or geothermal hot spots), has been measured.


The ocean heat increase is a function of CO2 pollution, not warming from below. Yes, there are volcanoes on the sea floor. But the amount of heat now being reflected back into the oceans from the IR CO2 and water vapor GHG blanket is over 99% of the scientifically measured increase in ocean heat.


All the above cause Persistent Weather Patterns .
 
As Dr. Francis points out, CO2 pollution that causes global warming is THE reason for Persistent Weather Patterns.


The cause of global warming and the crazy weather it brings is not limited to CO2 pollution. But all the other contributing factors to Earth's climate like volcanic activity and warming from beneath are, according to the scientific consensus and the insurance companies that pay VERY close attention to what may damage insured property, not statistically increasing significantly.
