Final answer:
Particles ejected into the atmosphere by a volcanic eruption can cool the climate through haze-effect cooling, resulting in lower global temperatures.
Step-by-step explanation:
Particles ejected into the atmosphere by a volcanic eruption can cool the climate. This is because volcanic eruptions release gases and solids, such as sulfur dioxide and ash, that can block out sunlight. This phenomenon, known as haze-effect cooling, can lead to lower global temperatures for one or more years. An example of this occurred in 1783 when volcanic eruptions in Iceland caused a haze-effect cooling, resulting in some of the lowest average winter temperatures on record.
