Earth’s Magnetic Field Decaying at an Alarming Rate

"A new paper in PNAS, and a Commentary about it by John Tarduno in the same issue of PNAS, provide an up-to-date look at the problem from the secular long-ages viewpoint. Basically, in the first paper, Trindade et al studied stalactites in a South American cave looking for clues to variations in the geomagnetic field. Secular geophysicists have identified a “South Atlantic Anomaly” (SAA) in geomagnetic measurements, “the position of the weakest geomagnetic field on Earth.” They suspected that variations in the SAA might have been recorded in the speleothem data. Here’s what they say about their work. Notice that they acknowledge a “fast decay” the the magnetic field’s strength."

“He considered the various proposals for maintaining the field, but none of them work, he concluded”

Tax it.

Global warming’s fault.

RE: Earth’s Magnetic Field Decaying at an Alarming Rate

Is this also Anthropogenic like Global Warming? /sarc

Fig. 3. Continuous magnetic results and comparison with geomagnetic models. Shown are radiometric ages (U-Th), magnetic declination, MAD, magnetic inclination, and relative paleointensity for specimens from Alho 31 (dark green) and Alho 06 (dark blue). Paleomagnetic results are compared with global geomagnetic field models for the Pau D’Alho cave location. CALS3k.4e (light blue) stands for “Continuous model from Archeomagnetic and Lake Sediment data” for the last 3 ka (17). Model ARCH3k.1 (orange) stands for “Archeomagnetic data” for the last 3 ka (17). Model HFM.OL1.A1 stands for “Holocene Field Model” (18). This last model accounts for archaeomagnetic, lava flows, and sedimentary data covering the past 10 ka and is less sensitive to outliers than CALS3k.4e yielding more stable estimates. From 1840 to 1990 CE, the three geomagnetic models are constrained by the gufm1 model (6). Also shown are the high-quality South American archeointensity data from bricks, ceramics, tile, and historic basalts for the last 700 y (pink squares and error bars); these data were relocated to the Pau d’Alho location for comparison (13).

From the Trindade et al article.

It’s because we’re using up all the electrons with our personal devices.

Mag Field Decay exacerbates Climate Change
Climate Change causes Mag Field Decay

I’ll bet on: Industrialized Western Governments raise taxes to solve Mag Field Decay.

[SkyDancer]

I just knew that global warming must have something to do with it.

[Yo-Yo]

further proof of Anthropogenic Climate Change.

Nothing to worry about. Global warming will cure it.

Geologic record shows numerous such changes over the very long term. Magnetic poles wander, weaken, strengthen, and flip. The current weakening does not bode well for us, but historically does point to a flip in the making.

As with “climate change”, beware those who decry global changes based on a few mere centuries of data.

Why would God create a magnetic field that would go away killing billions of people and animals?

[dhs12345]

Just when everyone got used to smartphones for navigation.

[Attention Surplus Disorder]

Damn that Trump!

[dhs12345]

Time for another mass mutation of species.

[Rurudyne]

We’re also propagating morons, a particle type in dark matter.

More fun than a flood?
