Question

Large volcanic eruptions send dust and ash into the stratosphere after these eruptions global air temperature are often

Answer 1

Global air temperatures often decrease after large volcanic eruptions due to the haze-effect cooling, which is caused by volcanic ash and sulfuric oxides blocking solar radiation and leading to cooler temperatures for a period of a few years.

Step-by-step explanation:

After large volcanic eruptions, global air temperatures are often cooled. This cooling effect, known as haze-effect cooling, results from the dispersal of volcanic ash, dust, and sulfuric oxides into the stratosphere, where they block incoming solar radiation. Notable historical examples include the eruptions in Iceland in 1783 and the Krakatoa eruption in 1883, which cooled global temperatures and disrupted weather patterns. While the volcanic particles contribute to short-term climate changes over a period of several years, they do not result in long-term changes since they remain in the atmosphere for much shorter periods than greenhouse gases (GHGs).

Answer 2

The global air temperature increases after the volcanic eruptions. It has also been observed that this increase in air temperature causes lowered winter seasons, acid rain, haze, dust, and ash. This causes problems in breathing and other disorders in humans as well as animals.
