Question
Which of the following is responsible for the
anthropogenic climate change phenomenon?Solution
The phenomenon of anthropogenic climate change refers to the changes in Earth's climate system that are primarily caused by human activities. While natural factors such as volcanic eruptions, variations in Earth's orbital characteristics (Milankovitch cycles), and variations in solar output can influence climate, the main driver of current climate change is the increased concentration of greenhouse gases in the atmosphere due to human activities.
