Description:
PUBLISHED
Volcanic eruptions are an awe-inspiring example of a natural driver of environmental change. At the local scale, erupted lava, ash and gases can have a drastic impact on the environment, with sometimes severe impacts on ecosystems, human health and economies. Global scale impacts can be produced by major volcanic eruptions, like those of Mt. Pinatubo (1991), or Tambora (1815). Such large-scale effects are due primarily to the injection of sulfur into the stratosphere, resulting in the formation of sulfate aerosols. The primary impact of these aerosols is a decrease in global temperature; however, the aerosols can also affect atmospheric circulation and precipitation patterns, leading to complex regional-scale climate impacts. Information on the climate anomalies resulting from volcanic eruptions in the Earth?s past therefore provides important insights for understanding the global and regional climate responses to external forcing agents. This in turn informs predictions of future climate change, such as that due to projected increases in anthropogenic greenhouse gases. Volcanically induced climate changes also provide valuable test cases for understanding the impact of climate variability on society.
