Climate change

The video explains how ice cores from Antarctica reveal Earth's climate history, showing natural warming and cooling cycles. It highlights the current rapid climate change, known as global warming, primarily caused by increased carbon dioxide from burning fossil fuels. This greenhouse effect is leading to rising temperatures, melting polar ice, and potential mass extinctions. The video stresses the importance of reducing carbon emissions to mitigate these effects.

What can scientists learn from analyzing ice cores from Antarctica?

• The future climate patterns

• The speed of current global warming

• The history of Earth's climate changes

• The exact temperature of the Ice Age

What is the primary cause of the current rapid increase in Earth's temperature?

• Increased solar activity

• Deforestation

• Natural climate cycles

• Rising levels of carbon dioxide

How does carbon dioxide contribute to the greenhouse effect?

• By trapping heat in the atmosphere

• By cooling the Earth's surface

• By absorbing harmful UV rays

• By reflecting sunlight away from Earth

What is a potential consequence of global warming on polar ice?

• Thicker ice layers

• Increased ice formation

• Stable ice levels

• Melting of large ice areas

What can individuals do to help reduce global warming?

• Reduce carbon dioxide emissions

• Increase fossil fuel usage

• Focus on other environmental issues

• Ignore climate change warnings
