Scientists in Iceland have warned that one of Iceland's biggest volcanoes, Bardarbunga maybe about to erupt. Erupting may lead to flooding or might throw out clouds of gas which could affect large parts of Europe. Bardarbunga is on an "orange" alert, the second-highest level of danger.

This is dangerous for people and the world because it might melt the surroundings which is usually Ice,I guess. But this could be a real problem to the polar Ice caps and if it melts… It could cause sea levels to rise.
