Tell me can volcanic eruptions affect climate?
Submitted by: MuhammadLarge volcanic eruptions can cause global climate change and even be responsible for mass extinctions.
Major eruptions in Kamchatka Peninsula, Russia have a disproportional effect on global climate, due to the low troposphere elevation at these latitudes, and the ease of dispersal of ash, aerosol, and gas.
Most mass extinctions during the last 500 million years coincide with eruptions of large igneous provinces. The Cretaceous-Tertiary extinction was synchronous with the Deccan flood volcanism.
There is a positive feedback between glacial variability and atmospheric CO2 concentrations: deglaciation increases volcanic eruptions, raises atmospheric
CO2, and causes more deglaciation. Conversely, waning volcanic activity during an interglacial could lead to a reduction in CO2 and the onset of an ice age.
