i've researched this topic previously and have seen all sides, but one of the more interesting theories, and one that makes the most sense to
me(because the earth has warmed and cooled many times long before the industrial revolution) is this site that tells of a very large amount of
volcanic activity in the oceans leading to warming oceans and increased precipitation .. like the record snowfalls in the west this year and the east
heres some quotes from it..
Exploring the ocean floor in an area known as the Mariana Trench, the researchers “found bubbles of liquid carbon dioxide being released into the
sea, enlarging up to a thousand times and turning to gas as they drifted upward.”
"March 14, 2005 - Hundreds of underwater volcanoes are erupting all over the world, especially around the Ring of Fire, reports the India Daily.
Underwater volcanoes are erupting in Australia, Greece, New Zealand and many other countries including the American Northwest, which is experiencing
an unprecedented level of underwater volcanism.
Andaman Nicobar Island is experiencing underwater volcanism in both the Indian Ocean and the Bay
of Bengal .
20 April 2005 - New evidence confirms that sea levels have risen and fallen much more quickly and frequently than previously believed. A new method of
dating dead corals reveals a long record of repeated rises and drops in sea level of 6 to 30 meters over just thousands of years.
That's too fast to be explained by regular shifts in the Earth's orbit that are usually considered responsible for the ice ages, as well as the loss
or gain of water from the oceans"
12 Dec 05 - An enormous hydrothermal "megaplume" found in the Indian
Ocean serves as a dramatic reminder that underwater volcanoes likely play an important role in shaping Earth's ocean systems
The plume, which stretches some 43.5 miles long, appears to
be active on a previously unseen scale.
"This thing is at least 10 times—or possibly 20 times—bigger than anything of its kind that's been seen before,"
Researchers also announced newly discovered deep-sea hydrothermal fields in the Arctic Ocean and the south Atlantic .
The appearance of hydrothermal vents around the world suggests that they are a far more common part of the ocean system than once believed and could
be a major influence on circulation patterns and ocean chemistry. (read: gulf stream)
Hydrothermal vents are volcanic hotspots that emit gasses(c02 and mineral-enriched water as hot as 760°F (400°C).
Megaplumes like the one found in the Indian Ocean are probably caused by undersea volcanic eruptions, though scientists aren't yet certain.
"Once formed they can possibly hang around for years," Murton said. The heat from such events could have a dramatic effect on ocean circulation,
which plays a role in determining Earth's climate.
"A normal hydrothermal vent might produce something like 500 megawatts, while this is producing 100,000 megawatts. It's like an atom bomb down
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
As the oceans warmed, evaporation increased. The excess moisture then fell to the ground as giant blizzards, giant storms and floods, and a new ice
this is a relativily interesting theory, and seems to coincide with some other aspects of ice ages previously discussed
like ocean tempuratures and ocean levels rising at the same points in time as c02 and air temps increase.
by looking at this graph..
and comparing it to this one
