A volcanic eruption is essentially the only natural way for short-lived – less than a few years – gases like sulfur dioxide and water vapor to make it into the stratosphere.
The conversion of sulfur dioxide to sulfuric acid, which condenses rapidly in the stratosphere to form fine sulfate aerosols. A volcanic winter is a reduction in global temperatures caused by droplets of sulfuric acid obscuring the Sun and raising Earth's albedo (increasing the reflection of solar radiation) after a large, sulfur-rich, particularly explosive volcanic eruption.
After a volcanic eruption, evaporation over ocean will lower, because it is largely determined by the ocean surface temperature change. The quick response of evaporation to the surface cooling and the delayed response of river runoff to the associated lower precipitation lead to an increased sea level.
As the planet warms, the impacts of eruptions could get a lot worse, disrupting global temperatures and precipitation for years to come. Climate change might make effects of major volcanic ...
External forcings include natural phenomena such as volcanic eruptions and variations in the sun's output. [11] Human activities can also impose forcings, for example, through changing the composition of Earth's atmosphere .

A related phenomenon driven by climate change is woody plant encroachment, affecting up to 500 million hectares globally. [218] Climate change has contributed to the expansion of drier climate zones, such as the expansion of deserts in the subtropics. [219] The size and speed of global warming is making abrupt changes in ecosystems more likely ...
The scientific consensus is that the main cause of the extinction was the flood basalt volcanic eruptions that created the Siberian Traps, [64] [65] which released sulfur dioxide and carbon dioxide, resulting in euxinia (oxygen-starved, sulfurous oceans), [66] [67] elevated global temperatures, [68] [69] [70] and acidified oceans.
