New Antarctic heat map reveals hot spots beneath the ice

Geothermal heat sources suspiciously close to areas where the ice has been melting.

An international team of scientists led by British Antarctic Survey (BAS) has produced a new map showing how much heat from the Earth’s interior is reaching the base of the Antarctic Ice Sheet. The map was published last week (13 Nov 2017) in the journal Geophysical Research Letters.

According to a press release from the BAS, “the team has produced the most up to date, accurate and high-resolution map of the so called ‘geothermal heat flux’ at the base of the Antarctic Ice Sheet.”

“Magnetic measurements mainly collected by aircraft reveal the ‘hot spots’ under the West Antarctic Ice Sheet and on the Antarctic Peninsula. These areas are the most rapidly changing areas of the Antarctic Ice Sheet.” (Italics added.”

“The new study from BAS uses over 50 years of magnetic measurements that were collected from thousands of hours flying over the continent. Warmer rocks lose their magnetic properties, and so the team was able to use the loss of magnetism in certain areas to calculate an estimate of the geothermal heat flux.”

You’d think a discovery such as this would make it clear that geothermal activity is melting the ice. But oh, no, the BAS has other ideas.

Even though “the most rapidly changing areas of the Antarctic Ice Sheet” (areas where the ice is melting) are located in the same areas as the geothermal hotspots, the BAS seems unable to grasp that there may be a cause-and-effect relationship.

“The ice loss we’ve seen in recent decades is actually the result of changes in air and ocean temperatures,” says BAS Science Director and glaciologist Professor David Vaughan.

Uh huh. I wonder if Professor Vaughn also thinks El Niño (which warms the Pacific Ocean) is caused by humans.

  1. What is strange is that the measured heat differential is “near” the volcanoes they have mapped. Incredible!!! they can point it out on paper but mentally cant tie one event to the other.

  2. This just proves that they are lying to the public and are hoping someone from the IPCC comes up with some plausible talking points. I can’t wait to hear their latest nonsense.

  3. Not a lot of other ways to get melting when it’s consistently below average temperatures, and it’s not most of the continent.

  4. This is quite strange, it needs to be mentioned:

    On the pretty popular Italian weather site, meteolive.it, looks like they have just discovered Robert Felix’s famous book “Not by fire but by ice” and yesterday they made a post about it.

    The post is very good and well written but what is strange is that by reading it you got the impression Felix’s book has just been translated and published in Italian! Here the link:

    PS: it also looks like some Italian warmists have not appreciated too much this post and taken the chance to provide some salty comments about it….

  5. My suggestion is to take these scientists and drop them directly onto the lava being emitted from live volcanoes in Hawaii.
    Then let them claim that their feet are burning and all the air around them is unbearably hot because of global warming– not because of molten lava.

  6. What’s really odd, is that the worlds primary CO2 sensor is parked in the middle of a major Volcanic island chain, smack in the middle of the Pacific upwelling zone of all that cold water, heavily laden with CO2, before it warms and releases much of its CO2 payload before the warm water makes its journey back to the North Atlantic as part of the surface overturning current, a journey of a thousand years before returning to the same position.
    A thousand years ago, the climate was warmer than now and for a much longer period, than this brief spike in contrived temperatures.

    https://en.wikipedia.org/wiki/Thermohaline_circulation.
    Wind-driven surface currents (such as the Gulf Stream) travel polewards from the equatorial Atlantic Ocean, cooling en route, and eventually sinking at high latitudes (forming North Atlantic Deep Water). This dense water then flows into the ocean basins. While the bulk of it upwells in the Southern Ocean, the oldest waters (with a transit time of around 1000 years)[3] upwell in the North Pacific.[4] Extensive mixing therefore takes place between the ocean basins, reducing differences between them and making the Earth’s oceans a global system. On their journey, the water masses transport both energy (in the form of heat) and matter (solids, dissolved substances and gases) around the globe. As such, the state of the circulation has a large impact on the climate of the Earth.

  7. According to the legend on the map, it was produced by taking only 4 measurements. At least I can only find 4 measurement symbols on the map. Most of it then, was computer modeled. Funny how you can make definitive statements about a whole continent with only 4 measurements.
