Surpising Inner Earth Discovery

Ancient rises in sea levels and global warming are partially attributable to cyclical activity below the earth’s surface, researchers from New York University and Ottawa’s Carleton University have concluded in an analysis of geological studies.

However, the article’s authors, NYU’s Michael Rampino and Carleton University’s Andreas Prokoph, note that changes spurred by the earth’s interior are gradual, taking place in periods ranging from 60 million to 140 million years—far less rapidly than those brought on by human activity.

Their analysis appears in Eos, a newspaper published by the American Geophysical Union.

Rampino and Prokoph’s analysis considers long-term fluctuations in global climate, diversity of marine organisms, and sea level changes, aiming to identify a unifying cause for these changes. While much scientific study has centered on phenomena above the earth’s crust, less attention has historically been paid to changes deep inside our planet.

In recent years, however, researchers have examined the upwelling of mantle plumes—the rising up of heated rocks from earth’s mantle that reach the earth’s surface. These plumes have a notable impact on one geologic occurrence: the eruption of large igneous provinces (LIPs), which are large accumulation of rocks formed from congealed lava.

In their analysis of recent scientific findings, Rampino and Prokoph observe that mantle plumes coincide with cyclical surface changes, suggesting that the plumes themselves may be cyclical in nature. For example, Prokoph’s previous research has found that many geological changes had cycles of 60 and 140 million years and suggested the cyclical uprising of these plumes to form hotspots—areas on the earth’s surface where volcanic activity has endured.

More broadly, the researchers write, mantle plumes push up against the earth crust, shifting water to continents, thereby producing sea-level rise, and precipitating volcanic activity, which produces additional CO2, leading to a warmer climate.

“Mantle plumes appear to show regular cycles,” Rampino explained. “So what’s remarkable is there is a strong indication of a connection between changes on the earth’s surface—such as volcanic activity and rising sea levels—and what’s occurring deep inside the earth. This suggests a fascinating and powerful union between below-surface geological events and changes in our climate.”

      Apparently the inner Earth may be a lot more volatile than previously thought. Thanks for the posting.

    • wizard

      What a load of crap.
      There is no molten core in the center of the earth.
      It is hollow, same a s the sun, hollow.

        The only thing that is hollow is your Head moron .

      • rakia

        It’s hard to know what’s true and not true when they lie about everything. Gotta see for yourself( with your own eyes) to know the truth

    • fuzzy696

      MILLIONS and MILLIONS of years……anyone think we,ll be here to witness this,time to take a journey to the center of the earth…..loved both versions of the books.

    • ps

      The Earth is Hollow.

      • JD

        so is your head. it’s called gravitational force, look it up.

    • Idiot Proof

      Hollow Earth…When the nuke at the bottom of the ocean was set off, about 50 or so miles off the Japanese coast, that was the actual cause of the tsunami two years ago, (the quake was HAARP induced), the planet rang like a bell, with vibrational ripples for at least 5 minutes. A solid sphere could not possibly react in that manner…

    • anonymoustache

      How does anyone know what is inside the earth when there is no actual data that goes much beyond the crust?

      IT’S ALL SPECULATION!

    • Anonymous

      Really? The earth isn’t hollow??? Who knew???

    • Pix

      Erm, CO2 causes GW has been disproven. By the fact that CO2 levels are at an all time high but the mean temperatures have been falling for the past 2’000 years.

      Amazing how only the warming aspects are mentioned, the hottest day, the longest warm spell, but they conveniently forget to mention we’ve also been experiencing the coldest temperatures. That we are in an interglacial period, and at the end of one at that, within the coldest part of an ice age.

      rubbish. the earth is hollow. like the moon, and the planets. . this is disinformation probably coming from a 6th grade science book.

    • Joerg Klaemt

      After reading these Articles I am beginning to believe that the Effect of Chemtrails and Haarp is already taking effect.
      Or is your Elite controlled schooling system failing you in the Americas?

    • pastorpatriot

      Actually it is not hollow it is plasma. The idea that the core of the earth is molten anything is pure bs. Molten metal cannot hold or produce a magnetic charge. Stop believing these overeducated morons and use some common sense.

      You may like to learn some real truths if you study the works of Eric P Dollard. or N Tesla.
      Even he knew and accepted Einsteins theory and conclusion of the Speed of light Its value being 299,792,458 metres per second or 186,282 miles per second.
      You claim radio Waves are faster? Radio Waves are reflected and absorbed,therefore you can not transmit a Signal THROUGH the earth period.
      If you are talking about Neutrinos than you are not speaking about Radio Waves.
      What country provided your Schooling?

      plasma core is a definite posiibility, but I think the purpose of this article is to let people know that the earth is changing, BUT, it blames the increase in changes on humans. This is to distract people from the rarely talked about idea that the sun is changing the earth and all the planets within the solar system.

    • YouGottaBeKidding

      Loosen up that tin foil hat Bubba! It’s squeezing your brain! :lol: :lol: :lol: :lol:

    • Louis

      Scientists theorize that there is more water inside the earth than there is on its surface.

    • wizard

      No its fact. You can send radio signals through the earth. They travel faster than light. Besides molten iron does not produce magnetic flux. You may like to learn some real truths if you study the works of Eric P Dollard. or N Tesla
      We live in an electric universe.
