Are there British volcanoes
Climate study Iceland's volcanoes will erupt more often
Climate change will make Europe more likely to deal with ash clouds from volcanic eruptions in Iceland. British climatologists at the University of Leeds are warning against this. According to their study, more volcanic eruptions are foreseeable in Iceland in the future as the glaciers melt. "When the glaciers melt, the pressure on the earth's crust decreases. This in turn also changes the pressure conditions underground in the chambers in which magma forms," explains Dr. Ivan Savov in the magazine "Dailyscience" and explains:
Even small changes on the surface increase the likelihood that ice-covered volcanoes will become active and erupt.Dr. Ivan Savov
The background to these warnings are long-term analyzes of volcanic ash from Iceland, which were found in peat deposits and lake sediments. They date from the period 4,500 and 5,500 years ago, which after a previous cold period was characterized by strong glacier growth and weak volcanic activity. According to the researchers, Iceland is currently once again undergoing climate change: the period between 1500 and 1850 in Iceland was considered by geologists to be the "little ice age" with a cooler climate. Since then, the climate in Iceland has warmed up and caused the glaciers to melt.
And why do we care in Europe?
When it gets warmer in Iceland, not only the people of Iceland feel it. The rise in temperature triggers a series of chain reactions, warns the British researcher Graeme Swindles in "Dailyscience": "What is happening today will affect future generations, and the concrete consequences are not completely clear: ash clouds over Europe, more particles in the atmosphere and problems in air travel. " According to Swindles, it is difficult to predict whether and when people will actually feel the effects of global warming in Iceland. The connections from the past between volcanic activity and glacier thickness clearly showed that there will be more volcanic eruptions in Iceland in the future. The example of the Laki volcano in 1783 shows that eruptions can have far-reaching consequences. Its eruptions lasted several months and large parts of Europe were covered with poisonous ash and caused crop failures and mass deaths due to a "global winter".
German scientists are also observing the effects of eruptions in northern volcanoes. Scientists from Forschungszentrum Jülich and the Chinese Academy of Sciences have now used computer simulations and satellite observations to show how they influence the global climate.
