Volcanos Happen, Then Global Cooling?
Volcano Eruption in Iceland Could Cause Gobal Cooling
March 25th, 2010
Digital News Report – Scientists are uncertain what the effects of the eruption of a volcano in Iceland will have on the world, but there are worries of global cooling if an event occurs. Last Christmas geologists started noticing deep earthquakes and the expansion of the earth’s crusts near the Eyjafjallajökull glacier and volcano.
Now the volcano is spewing and burping lava at the surface. Steam and ash are being expelled form the open hole in the earth and scientists worry that if the volcano grows larger it could melt the glacier.
The bigger danger is that this eruption could trigger a major eruption of Katla, a neighboring volcano with a much larger magma chamber. Geologists believe that in the past the Evjafaillaiokull eruption was a precursor to larger eruptions by Katla.
Katla could spew much more ask and sulfur into the atmosphere causing the northern hemisphere to become bitterly cold.
