What is Climate Change? Crash Course Geography

The video discusses the loss of glaciers due to climate change, focusing on Okjokull Glacier in Iceland. It explains the differences between climate change and global warming, highlighting the role of human activities in recent warming trends. The video explores how proxy data, like ice cores, help understand past climates and the causes of climate change, including natural and human-induced factors. It emphasizes the unequal impact of climate change on different regions and the shared responsibility to mitigate its effects. The video concludes with a call to action for individuals, corporations, and governments to reduce emissions and adapt to changing climates.
