An imminent ice-age?
“New findings point to cosmic rays and the sun — not human activities — as the dominant controller of climate on Earth,” says this article by Lawrence Solomon.
“The research, published with little fanfare this week in the prestigious journal Nature, comes from über-prestigious CERN, the European Organization for Nuclear Research, one of the world’s largest centres for scientific research involving 60 countries and 8,000 scientists at more than 600 universities and national laboratories,” Solomon continues.
CERN built the Large Hadron Collider
“CERN is the organization that invented the World Wide Web, that built the multi-billion dollar Large Hadron Collider, and that has now built a pristinely clean stainless steel chamber that precisely recreated the Earth’s atmosphere.”
In this stainless steel chamber, 63 CERN scientists from 17 European and American institutes have demonstrated that “cosmic rays promote the formation of molecules that in Earth’s atmosphere can grow and seed clouds, the cloudier and thus cooler it will be.”
Cosmic rays seed cloud formation
In other words, cosmic rays seed cloud formation, just as the Danish physicist Henrik Svensmark has long postulated.
“Because the sun’s magnetic field controls how many cosmic rays reach Earth’s atmosphere (the stronger the sun’s magnetic field, the more it shields Earth from incoming cosmic rays from space, the sun determines the temperature on Earth,” Solomon explains.
And here’s where magnetic reversals come into the picture.
You see, not only does the sun’s magnetic field shield us from cosmic rays; the earth’s magnetic field – the magnetosphere – also shields us from these energetic subatomic particles. The stronger the earth’s magnetic field, the greater the protection. The weaker the field, the less protection.
During a magnetic reversal our magnetosphere disappears
Prior to previous geomagnetic reversals, the earth’s magnetic field strength declined to about 15 percent of normal before suddenly reversing. During the reversal, scientists believe that magnetic field strength dropped to zero, thus disabling our protective shield.
With no shield, huge amounts of cosmic rays would have have rained down on our planet, thereby seeding the clouds (just as CERN suggests), leading to vast amounts of precipitation, cooler temperatures, and thence to an ice age.
Magnetic field strength is declining rapidly
The earth’s magnetic field strength has declined by about two thirds during the past 2,000 years. Unfortunately, the rate of decline is picking up. Magnetic field strength has declined about five percent in the past 100 years alone. (Not by Fire but by Ice, p 190.)
This increase in the speed of the decline is worrisome enough. But just this year, the British Geological Survey (BGS) admitted that we may now be headed for a magnetic reversal.
The South Atlantic Anomaly is growing and spreading westwards from South Africa as the Earth’s internal magnetic field rapidly weakens in this region, says the BGS. “This may be early evidence of a forthcoming reversal in the direction of the Earth’s internal magnetic field.”
The BGS is so concerned about our weakening magnetic field that they have opened an observatory on South Georgia Island to track the latest developments.
If CERN and the BGS are correct – and I think they are – then we’re in for some tough times ahead.
We need to prepare for an ice age
At least seven magnetic reversals during the past 400,000 years can be correlated with glaciation. (Not by Fire but by Ice, p 198) To think it won’t happen again just because we humans now inhabit the planet would be wishful thinking.
Forget all this talk about global warming. We need to prepare for an ice age.
