You are somehwat correct. First of all we have the earth's mantle and crust. The plates ride on the outer core which is liquid hot iron.

Not quite accurate. The plates which make up the crust move over the mantle, which is solid but due to the heat is quite ductile and has very slow moving convection currents, which cause the plates to move.

The plates do not ride over a molten core.

You are correct. I am used to oversimplying for some lay people I talk to. Should not on this forum.

Quite agree BFTV. Just to add the strong and rigid plates ride on a relatively weak viscous asthenosphere and move relative to each other over the Earth's surface. As BFTV mentioned the plate movement is driven by mantle convection the main mechanism by which heat, derived from radioactive decay, is transferred from the Earth's deep interior to the surface. This being the case I'm at a loss to know what gravity has to do with it.

Earth's Energy Budget Remained Out of Balance Despite Unusually Low Solar Activity

A new NASA study underscores the fact that greenhouse gases generated by human activity -- not changes in solar activity -- are the primary force driving global warming.

Quote

"The fact that we still see a positive imbalance despite the prolonged solar minimum isn't a surprise given what we've learned about the climate system, but it's worth noting because this provides unequivocal evidence that the sun is not the dominant driver of global warming," Hansen said.

Rightly or wrongly, I have little faith in anything which has James Hansen in the mix.

Oh I don't know, The Muppets were alright. Or was that Henson? "Muppet" springs to mind, either way.

I am a fan of the impacts of our electromagnetic field on a person but on a planet? I'd tend to think that heating of the crust , and thermal expansion (as we saw in the French Nuke power stations in 03') , puts more of a stress along fault planes than our electromagnetic field?

To me the field is far to subtle a beastie to impact the masses involved in earthquakes?

Now the workings of a Human brain (the electro-chemical exchanges) and a fluctuating electromagnetic field cycling across the spectrum.........

No,silly! I was perusing the NW climate change forum and saw Hansen mentioned. J - AGW is a panto which has had an extraordinarily long run but the final curtain is due to fall.

Extreme Downpours Could Trigger Earthquakes

Can severe weather trigger earthquakes?

Discovery.com, Dec. 12, 2011

Monsoons, hurricanes and other extreme weather events may trigger earthquakes when faults are ready to rumble.

The new research presented this week at the American Geophysical Union's annual meeting in San Francisco does not suggest that all earthquakes are caused by storms or that all storms cause quakes. But by identifying some of the many conditions that put stress on faults, the new work may help scientists better forecast future tremors.

Experts hope to develop more accurate ways to warn the public before massive devastation ensues.

"There's a holy grail for any geophysicist being able to one day predict earthquakes," said Thomas Ader, a graduate student in geophysics at the California Institute of Technology in Pasadena. "All we're doing now is trying to understand, after earthquakes happen, why they happened."

And the nutters have been saying that the world is getting warmer and we're all doomed etc for much,much longer. Most everyone in the real world is bored to death of it. Maybe you're right Pete,and that this charade still has legs. I mean how many other myths have stood the test of time and endured for centuries?

[Gray-Wolf]

<sup>The trend is for a warming world and at a time when cold drivers should be placing us on the negative side of the average global temp? The folk in denial told us to wait for the cold (throughout the noughties) and we waited. all that occured was the world warmed up some more??

seems these 'nutters' have a better feel for the climate than these denialist 'realists' that have things all upside down.

To cap it all we are now told that the second decade of this century will see the cold set in with other of that denomination alredy telling us we must wait until 2020 for the 'cooling' to set in???

I'll stick my neck out here and predict that with the demise of the cold drivers influence we will see global temps increase faster, from now on, than they did in the noughties and that the next El-Nino (sometime in the next 18 months) will push global temps to a new record high. I also predict that the methane releases over the coming 5 years will influence climate.

There!, I said it.</sup>

Yep.. You said it...... Thing is though, even the main boffins have admitted that this pause wasn't expected and even they are predicting some cooling... Are you saying that they are wrong? Where's the proof? Surely we must believe them as they aren't wrong. At all. End of..... You denier you.

I'm still running with the predictions I read in the mid noughties (esp. from MetO?) which conceded that natural variability would lead to a slow down in temp rises but that , by 2015, temps would ,once again, speed up there warming trend to a rate beyond the 80's rate of warming.

I can see that the PDO-ve has peaked and so would expect this to now drop away as an influence (the background warming will 'swamp' the signal so we can expect a shorter phase of -ve but a longer phase of 'null' plots) and we are now expecting a La Nina. Though moderate (and in a PDO-ve phase which tends to moderate the Nino's) the last Nino was only trumped .in it's effects on global temps. by the 98' Super Nino so it seems logical that ,during the waning of PDO-ve, the next one will break the global temps of 98'.

Heightened global temps is not what we need with the Siberian shelf deposits becomeing more unstable and land based permafrost melt producing ever more 'lakes' producing methane.

This years Sea Ice melt seasson is nearly upon us so we'll have our 'early season fun there,by which time the ENSO forecasts will show the next Nino and we'll have more of an idea as to what summer will bring us all this year.

Sombre,leaden skies with suppressed temps,howling winds and Biblical rains with any luck. That would be nice in itself but we really do need something,anything to sabotage the borefest of the bloody Olympics. I wish it was September. There's a song in there,somewhere.

A group of Russian scientists plumbing the frozen Antarctic in search of a lake buried in ice for tens of millions of years have failed to respond to increasingly anxious U.S. colleagues -- and as the days creep by, the fate of the team remains unknown

"No word from the ice for 5 days," Dr. John Priscu -- professor of ecology at Montana State University and head of a similar Antarctic exploration program -- told FoxNews.com via email.

The team from Russia's Arctic and Antarctic Research Institute (AARI) have been drilling for weeks in an effort to reach isolated Lake Vostok, a vast, dark body of water hidden 13,000 ft. below the ice sheet's surface. The lake hasn't been exposed to air in more than 20 million years.
Priscu said there was no way to get in touch with the team -- and the already cold weather is set to plunge, as Antarctica's summer season ends and winter sets in.
