While volcanic ash falls on Britain, in yet another assault on reason, the Royal Society has warned :
In papers published by the Royal Society, researchers warned that melting ice, sea level rises and even increasingly heavy storms and rainfall predicted consequences of rising temperatures could affect the Earths crust.
I also watched the movies 2012 and The Day After Tomorrow, but apparently I didnt take them as seriously as some Zombieland was probably more realistic.
As the land rebounds back up once the weight of the ice has been removed which could be by as much as a kilometre in places such as Greenland and Antarctica then if, in the worst case scenario, all the ice were to melt it could trigger earthquakes. The increase in seismic activity could, in turn, cause underwater landslides that spark tsunamis. A potential additional risk is from ice-quakes generated when the ice sheets break up, causing tsunamis which could threaten places such as New Zealand, Newfoundland in Canada and Chile.
Pleeezzz . Even if these claims worth worth considering, it would take tens or hundreds of thousands of years for Greenland and Antarctica to melt.
Back in the real world we hear from the Icelandic Meteorological Service that the glacier is what is causing the ash :
Einar Kjartansson, a geophysicist at the Meteorological Office.believes the volcano has melted about 10 percent of the glacier
It still could take months for the volcano to burn through the rest of the glacier, to a point where the steam and ash would turn instead into lava, he said.
What he is saying is that the sooner the glacier melts, the sooner the volcanic hazards will subside. This must be tough to swallow for people who believe that world is better off when it is cold and icy.
When Mount St. Helens erupted, Jimmah Carter had this
idea to quench the eruption by print money and bombing
the volcano with the money.
He then wanted Mount St. Helens to be renamed the Magma Carter.
This is getting crazy.
ROFL!
This was the same group that said heavier than air machines were impossible ...
So global warming caused the volcano to erupt? Well, good. All that ash will cool things down.
We all learned just a few days ago that if you put too many Marines on an Island, it will capsize. See where I’m going here? Time to call out the Marines, have them tip the island over and extinguish the Volcano.
Scientists call for research on climate link to geological hazards

Scientists today called for wide-ranging research into whether more volcanoes, earthquakes, landslides and tsunamis could be triggered by rising global temperatures under global warming.
Significant warming of the atmosphere in the distant past can be linked to changes in geological activity, they say. Suggestions that climate change predicted for coming decades could bring similar changes remain speculative, but the scientists say there is enough evidence to take the threat seriously. Some experts have already linked current levels of global warming to rockfalls and landslides in mountain regions.
Richard Betts, a climate modeller at the Met Office Hadley Centre in Exeter, said: "This is a new area of academic research with potentially interesting implications. It was previously assumed there was no link at all between climate change and these events, but it is possible to speculate that climate change might make some more likely. If we do get large amounts of climate change in the long term then we might see some impacts."
He said there was no evidence that current levels of global warming were influencing events such as last week's earthquake in China that killed hundreds of people and the volcanic eruption in Iceland that grounded flights across Europe.
Experts say global warming could affect geological hazards such as earthquakes because of the way it can move large amounts of mass around on the Earth's surface. Melting glaciers and rising sea levels shift the distribution of huge amounts of water, which release and increase pressures through the ground.
These pressure changes could make ruptures and seismic shifts more likely. Research from Germany suggests that the Earth's crust can sometimes be so close to failure that tiny changes in surface pressure brought on my heavy rain can trigger quakes. Tropical storms, snowfall and shifting tides have all been linked to shifts in seismic activity.
I have a crazy idea,,,If a volcano decides to do anything fun, maybe we have to accept it and work around it, rather than follow this insane British insistence that the earth remain exactly as it is now!
Ice cap thaw may awaken Icelandic volcanoes

Ice cap thaw may awaken Icelandic volcanoes An aerial handout photo from the Icelandic Coast Guard shows melting ice caused by a volcanic eruption at Eyjafjalla Glacier in southern Iceland April 14, 2010. The volcanic eruption on Wednesday partially melted a glacier, setting off a major flood that threatened to damage roads and bridges and forcing hundreds to evacuate from a thinly populated area.

OSLO (Reuters) - A thaw of Iceland's ice caps in coming decades caused by climate change may trigger more volcanic eruptions by removing a vast weight and freeing magma from deep below ground, scientists said on Friday.
They said there was no sign that the current eruption from below the Eyjafjallajokull glacier that has paralysed flights over northern Europe was linked to global warming. The glacier is too small and light to affect local geology.
"Our work suggests that eventually there will be either somewhat larger eruptions or more frequent eruptions in Iceland in coming decades," said Freysteinn Sigmundsson, a vulcanologist at the University of Iceland.
"Global warming melts ice and this can influence magmatic systems," he told Reuters. The end of the Ice Age 10,000 years ago coincided with a surge in volcanic activity in Iceland, apparently because huge ice caps thinned and the land rose.
"We believe the reduction of ice has not been important in triggering this latest eruption," he said of Eyjafjallajokull. "The eruption is happening under a relatively small ice cap."
Carolina Pagli, a geophysicist at the University of Leeds in England, said there were risks that climate change could also trigger volcanic eruptions or earthquakes in places such as Mount Erebus in Antarctica, the Aleutian islands of Alaska or Patagonia in South America.
MAGMA
"The effects would be biggest with ice-capped volcanoes," she said. "If you remove a load that is big enough you will also have an effect at depths on magma production."
She and Sigmundsson wrote a 2008 paper in the scientific journal Geophysical Research Letters about possible links between global warming and Icelandic volcanoes.
That report said that about 10 percent of Iceland's biggest ice cap, Vatnajokull, has melted since 1890 and the land nearby was rising about 25 millimetres (0.98 inch) a year, bringing shifts in geological stresses.
They estimated that the thaw had led to the formation of 1.4 cubic km (0.3 cubic mile) of magma deep below ground over the past century.
At high pressures such as under an ice cap, they reckon that rocks cannot expand to turn into liquid magma even if they are hot enough. "As the ice melts the rock can melt because the pressure decreases," she said.
Looks like we are dealing with a royal batch of idiots.
Sure appears that way!
What a bunch of Royal Ashwipes. (/family friendly)
It might also be the group that said in 1889 everything that could be invented had been invented.
I think it was the head of the US patent office that said that ... wanted to close it down ...
Ah yes that’s it. A like-minded thinker obviously.
I remember seeing a poster with stuff like that on it such as a Warner Brother saying “Who wants to hear actors talk” ... and someone from IBM saying something about home computers won’t be popular or impossible ....
in yet another assault on reason, the Royal Society has warned:In papers published by the Royal Society, researchers warned that melting ice, sea level rises and even increasingly heavy storms and rainfall -- predicted consequences of rising temperatures -- could affect the Earthâs crust... As the land "rebounds" back up once the weight of the ice has been removed -- which could be by as much as a kilometre in places such as Greenland and Antarctica -- then if, in the worst case scenario, all the ice were to melt -- it could trigger earthquakes.
