According to NASA’s Space Weather website the sun is in the middle of a solar minimum, with 266 sunspot-free days last year – the lowest for nearly a century.
5 Jun 09 – “Undersea volcanic activity triggered a mass extinction of marine life and buried a thick mat of organic matter on the sea floor about 93 million years ago, which became a major source of oil,” says a recent article in Science Daily.
As you already know if you’ve read Magnetic Reversals and Evolutionary Leaps, I think that oil was created in our very own skies. It was created, not as a result of the volcanic activity, but coincident with it.
U of A scientists Steven Turgeon and Robert Creaser say that the lava that erupted into the water “altered the chemistry of the sea and possibly of the atmosphere.”
I agree. In addition, I think that lava would have temporarily heated the seas.
Turgeon and Creaser found specific isotope levels of the element osmium, an indicator of volcanism in seawater, in black shale-rocks containing high amounts of organic matter-drilled off the coast of South America and in the mountains of central Italy.
Yes, black shales can contain huge amounts of carbon.
Here’s a quote from Magnetic Reversals and Evolutionary Leaps:
“A visitor center in Parachute, Colorado, tells of a homesteader who built a black shale fireplace in his new home, only to watch his house burn to the ground after lighting a fire for his housewarming party.”
I might also mention that black shales are 550 percent more radioactive than other sedimentary rocks. I think that’s proof, all by itself, that there were much bigger forces than mere volcanic activity going on at the time.
An odd side-effect of the underwater volcanic eruptions, say the two U of A scientists, “was that temperatures and carbon dioxide levels on the Earth’s surface actually dropped.”
All of that red-hot lava (2,150F hot) pouring into the seas leads to excess evaporation, which leads to more precipitation, which – if it falls in the winter – leads to an ice age and thence to lower CO2 levels.

Speculation raged across the internet yesterday after an article in the journal Science told of diamonds drizzling to the earth by the ton, supposedly caused by a comet exploding in mid-air.
14 Jul 09 – After reading your book Magnetic Reversals and Evolutionary Leaps I am just blown away! It has to be one of the greatest books ever written.
Or evidence of thousands of Tunguska-like explosions in the sky?
“The oil and gas that fuels our homes and cars (supposedly) started out as living organisms that died, were compressed, and heated under heavy layers of sediments in the Earth’s crust,”
“Earth’s north magnetic pole is racing toward Russia at almost 40 miles (64 kilometers) a year,” says this article in National Geographic News.
“A magnetic reversal would likely have a devastating effect on planet Earth and, frankly, I don’t want to be around when it occurs.” – Alan Caruba
“It’s completely accepted in science that cosmic rays can – and do – alter DNA,” says Andrew Collins in this short video.
I just want to add my voice to those of your many other admiring readers.
