Which is least likely to cause changes in global climate? A. a tsunami event B. excessive use of fossil fuels that release several tons of greenhouse gases C. a large meteorite hitting Earth D. a chain of volcanic eruptions

. a tsunami event<br /><br />Tsunamis are large ocean waves usually caused by underwater earthquakes or volcanic eruptions. While they can cause significant local destruction and loss of life, they do not have a direct impact on global climate. In contrast, the other options listed (excessive use of fossil fuels, a large meteorite impact, and volcanic eruptions) can all contribute to changes in global climate through mechanisms such as greenhouse gas emissions or atmospheric dust and aerosols that affect solar radiation.
