Movements of the earth's crust may mean that global warming driven by greenhouse gases from power stations and vehicle exhausts isn't the only threat to life the world faces.
About 700 million years ago, global temperatures fell so low that glaciers may have reached the equator. Snowball Earth may have all but extinguished life on the planet. But the only life at the time was microbial and dispersed in the oceans.
The planet survived: volcanic eruptions may have darkened the ice and pumped more carbon dioxide and steam into the atmosphere, and the world warmed again.
But, say two Texan scientists, the frozen plane in what geologists call the Neoproterozoic era may have been precipitated at the start by the first dramatic movements in the earth's crust or lithosphere, known as plate tectonics. That is, shifts in climate and shifts in the earth's crust could be linked.
Research like this is tentative: the authors offer a hypothesis to be challenged, rather than a theory to be confirmed. But research like this is fundamental: to understand the subtleties of the present climate, now inexorably being altered by human action, it is necessary to understand change in the past as well, and to establish the principles that control the planet's overall climate history.

or maybe not
These dishonest “scientists” really demonstrate that they are both worthless and desperate for grant money to pursue their idiotic theories. I have a theory: to cleanse science of these liar vermin, stop all grants for at least two decades.
If you back off into space, the earth looks like a basketball with a layer of dew on it. The idea that the condition of the atmosphere, within a even a hundred degrees of where it is now, would effect the continental plates is idiotic.
By the way, that photo Goebbels is the creepiest thing I see every day.
-—and free Gondwana-—
Liberal cons are still banging on about that and it's been a dead letter for at least a decade. People don't like coercive indoctrination.
Climate Change! Is there anything it can’t do?
I guess they can now take mother earth to court. Hell if they can boink her she ought to be able to show up in court.

Greenhouse gas aside, a primary problem is atmospheric ash pollution. It quickly gets picked up by winds aloft and speads around the earth.
The effects of that ash lasts in the atmosphere for many years. that ash reflects sunlight and results in wide spread cooling. You have raised an interesting fact about the green house gasses that prevent the radiation of heat.
Question...... does the volcanic green house gas warming effect offset the volcanic ash cooling effect?
Then, do the volcanic emissions affect the ability of wooly worms to adjust coloration to predict the coming winter?
Volcanoes..have caused changes in the world's climate..probably more than man has.
The article is so poorly written I can’t tell if it’s saying that climate change causes tectonic shift or tectonic shift causes climate change.
The former is pile of stinking dung and the latter could not be more true.
“to understand the subtleties of the present climate, now inexorably being altered by human action, it is necessary to understand change in the past as well, and to establish the principles that control the planet’s overall climate history.”
If the climate is being “inexorably” altered by human action, why are they attempting to stop what can not be stopped?
Generally, the volcanic ash causes temporary cooling of the atmosphere. How much cooling and how long depends on the size of the eruption.
Oh, and the causes some spectacular sunsets too.
The global warming, if it actually happens, would take longer to notice but would also be of longer duration. While ash clouds like happened from Pinatubo and Krakatoa caused demonstrable short-term cooling, I don’t know of any links from large eruption to delayed long-term warming.
I recently saw an excellant You Tube production on the Krakatoa eruption.
Included were paintings by an artist who traveled the world extensively to capture the sunsets resulting from the eruption. As I recall, the effects were lingering for as long as five years.
A FReeper put me on to You Tube war videos of which there seem to be an uncountable number.
For some reson, You Tube recommended the Krakatoa piece right in the middle of some war videos. I think it was because I followed a FRee Republic link describing the Hawaii erutptions.
Alas..... they know me too well
Well, yes. Mountains, the location of mountains, the proximity of land masses to the poles, and the relation of ocean currents to land masses are all driven by plate tectonics and have a great deal to do with the weather.
And volcanoes erupting!
One of my favorite thoughts is that is as the Atlantic Rift spreads, Manhatten will be shifted westward effectively raisingthe sea level.
The tectonic shift outpaces the sealevel rice contributed by global warming. Manhatten is saved
“understand the subtleties of the present climate, now inexorably being altered by human action.”
That’s a hypothesis too.
BM’s affected by climate change.
