Not by fire but by Ice

Here's an important study showing that
El Niño activity correlates with ice ages.
(Meyerson, Mayewski, et al., Annals of Glaciology 35: 430-436.)
The authors found that a shift toward cooler conditions during the Little Ice Age was concurrent with an increase in the frequency of El Niño events. This is contrary to what is generally predicted by climate models, where cooling leads to less El Niño activity and warming leads to more.

The findings were harmonious with the historical El Niño chronology of both South America and the Nile region, which depict "increased El Niño activity during the period of the Little Ice Age and decreased El Niño activity during the Medieval Warm Period.

This goes along with what I have been saying for years - that today's increase in El Niño activity is the precursor to an ice age.

We’ve forgotten that this isn’t the first time our seas have warmed. Sea temperatures also shot upward 10º to 18ºF just prior to the last ice age.

As the oceans warmed, evaporation increased. The excess moisture then fell to the ground as giant blizzards, giant storms and floods (Noah's Deluge type floods), and a new ice age began.

The same thing is happening today.

It’s not global warming, it’s ocean warming, and humans have nothing to do with it. Our seas are being heated, I believe, by underwater volcanism. Here’s why:

We are living in a period of vastly increased volcanism, said Dixy Lee Ray in her 1993 book Environmental Overkill, the greatest in 500 years.
Eighty percent of all volcanism (say experts at NOAA) occurs underwater.
Therefore, underwater volcanism should also be the greatest in 500 years.
Our seas, heated by underwater volcanism, are leading us directly into the next ice age . . . and we don’t even know it.
That's what El Niño is all about. Warmer seas send excess moisture into the sky, leading to increased precipitation.
Worldwide flood activity is the worst since before Christopher Columbus. In Poland, it's the worst in several thousand years. In the U.S., precipitation has increased 20 percent just since 1970. This is no coincidence.
When that precipitation begins falling in the winter, you have the makings of an ice age.
