Climate Change and Its Impacts

The video discusses climate change, its detection, and historical context. It covers methods like oceanic deposits and ice core analysis to study past climates. The impact of solar activity and other factors on climate is explored, along with historical and recent climate changes. The role of greenhouse gases and human activities in recent climate change is highlighted.
