What is a probable cause of global climate change?

Earth's orbit
Human activities
Changes in solar activity
Volcanic eruptions

The correct answer is: Human activities

Climate change, also known as global warming, is the long-term increase in Earth's average surface temperature. This is caused by the accumulation of greenhouse gases, such as carbon dioxide, which trap heat in the Earth's atmosphere. These gases are primarily generated by human activities such as burning fossil fuels, deforestation, and agriculture. While Earth's orbit, changes in solar activity, and volcanic eruptions can also contribute to changes in global climate, they are not the primary cause of the current rapid warming trend.
