In the recent Climate Change debate, some of our leaders are still insisting that these are cyclical, natural changes, or that Global Warming is not real because  "God is still up there", but this is not just about saving endangered species, or consumer choices or even energy security - we must face reality.
I foresee that a decade from now - when we see all that has happened, Senator Inhofe's comments on Climate Change will be viewed as some of the most misguided statements ever made by a Senator.

Why? There was a significant development that occurred today as an 8.3 Earthquake struck Samoa and set off tsunami warnings in the South Pacific.
Comparisons were being made to the Indonesian Earthquake which was the worst earthquake ever recorded at over 9 on the Richter scale.

While the people of the South Pacific seem to have avoided the Tsunami on the scale of Indonesia, these types of earthquakes and equally dangerous volcanoes are likely to increase in frequency worldwide - the reason - Climate Change.

How can this be? Well, the Earth's tectonic plates have sensitive fault lines, which when triggered to move, cause earthquakes and volcanoes.
The Earth as a sphere 'reflects' vibration internally, so that an earthquake in the South Pacific is picked up by seismologists across the world - say in Alaska. The Indonesian quake resonated so strongly, that it set off quakes in Alaska.
(Samoa also had a 7.9 earthquake in March.)

Now, add in this to the equation.
In Greenland, and to a lesser extent, Antartica, Ice sheets and glaciers are melting and more importantly, sliding in rapid bursts. This is caused by moulins, which are holes that melting water form from the top of a glacier to the bottom. The water then lubricates and melts the underside of the glacier, causing them to detach from the bedrock - and creating a 'slip-n-slide' for glaciers that weigh in the megatons - some the size of Manhattan.

Robert Corell, chairman of the Arctic Climate Impact Assessment, said in Ilulissat yesterday: "We have seen a massive acceleration of the speed with which these glaciers are moving into the sea. The ice is moving at 2 meters an hour on a front 5km [3 miles] long and 1,500 meters deep. That means that this one glacier puts enough fresh water into the sea in one year to provide drinking water for a city the size of London for a year."
The glacier is now moving at 15km a year into the sea although in surges it moves even faster. He measured one surge at 5km in 90 minutes - an extraordinary event.

The result, each 'slide' of these multi-ton glaciers sets off an 'ice quake' that register an average of 3 to 5 on the Richter scale.
This might sound minor, but these are occurring multiple times a year.
This means that the Earth is being jolted repeatedly by these ice quakes, destabilizing faults lines which has many, many consequences.

The latest scientific discipline to enter the fray over global warming is geology.
And the forecasts from some quarters are dramatic - not only will the earth shake, it will spit fire.
A number of geologists say glacial melting due to climate change will unleash pent-up pressures in the Earth's crust, causing extreme geological events such as earthquakes, tsunamis and volcanic eruptions.
A cubic metre of ice weighs nearly a tonne and some glaciers are more than a kilometre thick. When the weight is removed through melting, the suppressed strains and stresses of the underlying rock come to life.
(from Alan Glazner, a volcano specialist at the University of North Carolina)
"When you melt glacial ice, several hundred metres to a kilometre thick . . . you've decreased the load on the crust and so you've decreased the pressure holding the volcanic conduits closed.
"They're cracks, that's how magmas gets to the surface . . . and where they hit the surface, that's where you get a volcano."

And it is not likely to slow down, but likely speed up.

...quakes ranged from six to 15 per year from 1993 to 2002, then jumped to 20 in 2003, 23 in 2004, and 32 in the first 10 months of 2005 - matching an increase in Greenland temperatures.

This trend is causing changes exponentially, - for instance, since the Arctic has opened an Ice Free passage, the Arctic is no longer a stationary sea - currents from the Pacific and the Atlantic are encroaching into the Arctic circle and creating an additional heating feedback loop - which is as equally dangerous as heating feedback loop as the loss of reflective ice.
This video highlights the feedback loop that scientists are seeing in Greenland.

And, sadly, the latest report from the IPCC reflects this exponential change, as scientists report now that even if the world's countries commit to all of the recommendations to reach by 2050 - (which the US Senate is likely to block) the Earth's temperature will rise by 6.3 degrees by 2100.

This is not good, since Scientists worldwide have agreed to survive Climate Change, we must limit the temperature rise to 2 degrees.

So, not only are we on a path that with displace as many as 75 million people by 2050, many of them Islanders, but we are also putting many more people in peril due to the threat of this increased tectonic activity.

The industrialized countries must change their polluting policies and begin to think about their responsibility for the Indonesian Earthquake that resulted in 229,866 people lost, including 186,983 dead and 42,883 missing.

These may be the first wave of people who have died in a widespread fashion from the effects of Climate Change.

There are many changes that are going to happen, and we are going to have to realize, globally, that we are all in this together.

More Tagging tips:

A tag is a way to search for this diary. If someone is searching for "Barack Obama," is this a diary they'd be trying to find?

Use a person's full name, without any title. Senator Obama may become President Obama, and Michelle Obama might run for office.

If your diary covers an election or elected official, use election tags, which are generally the state abbreviation followed by the office. CA-01 is the first district House seat. CA-Sen covers both senate races. NY-GOV covers the New York governor's race.

Tags do not compound: that is, "education reform" is a completely different tag from "education". A tag like "reform" alone is probably not meaningful.

Consider if one or more of these tags fits your diary: Civil Rights, Community, Congress, Culture, Economy, Education, Elections, Energy, Environment, Health Care, International, Labor, Law, Media, Meta, National Security, Science, Transportation, or White House. If your diary is specific to a state, consider adding the state (California, Texas, etc). Keep in mind, though, that there are many wonderful and important diaries that don't fit in any of these tags. Don't worry if yours doesn't.
