Volcanic Eruptions Reduce Global Rainfall

Climate change is occurring all over the globe as 1°C increase in Earth’s temperature has led to the rise in the sea level, melting of the Arctic ice, and unseasonable heat waves and heavy snow.

Climate change is occurring all over the globe as 1°C increase in Earth’s temperature has led to the rise in the sea level, melting of the Arctic ice, and unseasonable heat waves and heavy snow. To accurately predict the artificial climate changes set off by the increase in greenhouse gases, it is important to understand the effects of natural factors such as solar and volcanic activities. A recent study has shown how global precipitation decreases when volcanoes erupt in the tropics.

Professor Seung-Ki Min and Dr. Seungmok Paik of department of environmental engineering at POSTECH and researchers from the French National Centre for Scientific Research, Zurich Institute of Technology, and Edinburgh University have released new findings that the El Niño induced by volcanic eruptions plays a key role in the decrease in global precipitation. So far, studies have shown that volcanic activity reduces precipitation across the globe, but its specific mechanism had been unclear. These research results were recently published in Science Advances, a sister journal of Science.
