Climate change is natural

Post  smelly-bandit on Wed Jan 31, 2018 3:57 pm

The Earth has a fierce molten core that generates a magnetic field capable of defending our planet against devastating solar winds.


The protective field extends thousands of miles into space and its magnetism affects everything from global communication to power grids.


But this magnetic field, so important to life on Earth, has weakened by 15 per cent over the last 200 years. 


And this, scientists claim, could be a sign that the Earth’s poles are about to flip.


In a new report, Daniel Baker, director of the Laboratory for Atmospheric and Space Physics at the University of Colorado, Boulder, claims there are signs of a reversal.


He says if this reversal happens, it is likely to render some areas of the planet 'uninhabitable' by knocking out power grids.

His comments were made in an in-depth Undark report written by Alanna Mitchell, who has a new book about the topic titled 'The Spinning Magnet: The Electromagnetic Force that Created the Modern World and Could Destroy It',

Mitchell writes: 'The dangers: devastating streams of particles from the sun, galactic cosmic rays, and enhanced ultraviolet B rays from a radiation-damaged ozone layer, to name just a few of the invisible forces that could harm or kill living creatures.'

Historically, Earth’s North and South magnetic poles have flipped every 200,000 or 300,000 years.

However a flip is currently overdue as the last one was about 780,000 year ago. 

The latest satellite data, from the European Space Agency’s Swarm trio which monitors the Earth's magnetic field, suggests a flip may be imminent.

The satellites allow researchers to study changes building at the Earth’s core, where the magnetic field is generated.

Their observations suggest molten iron and nickel are draining out of the Earth’s core - a 'restless activity' that suggests field is preparing to flip.

If a switch happens, we would be exposed to solar winds capable of punching holes into the ozone layer.

Would this be because of Brexit? The sky about to fall after all?

Of course the poles have flipped many times over geological time.

Yes and like a Yellowstone eruption its way over due, - apparently.

Yeah but overdue means thousands of years in the making

The world has looked after itself for the better part of a bit.

Yes, it has looked after itself. Storms take some land and build it up somewhere else, rivers change course, wetlands become dry and vice versa, animals move to other areas, as did early humans I suppose. Once we decided to build permanent settlements its increasingly became a problem until our settlements are so vast and our population so great we can't just get out of the way and we've hemmed in wildlife so that they have no where to re locate and are dying out. We are making such a mess of things.

Mostly due to over population,  especially our little island !

If tsunamis were regular occurances along the northern Pacific coast and now long overdue,  so too a Yellowstone eruption and pole shits are also overdue among other geological events, does that mean human activity has actually altered things to prevent them?

about every 600000 years or so. Last one about 600000 years ago.

about 600000 has a large margin of error

it could our by a couple of thousand of years and still be "about to blow"

either way , no amount of taxing the poor to feed the rich will change a damn thing
