Cambio climático

The video discusses the history of climate changes, highlighting how the Earth's climate has naturally fluctuated over thousands of years. It explains the current rapid warming trend known as global warming, primarily caused by increased carbon dioxide from burning fossil fuels. This greenhouse effect is leading to significant environmental impacts, such as melting polar ice and rising sea levels. The video emphasizes the urgency of addressing global warming by reducing carbon emissions to prevent further environmental damage.

What evidence do scientists use to study past climate changes?

• Ocean currents

• Ice cores

• Tree rings

• Fossil records

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

• Solar flares

• Volcanic eruptions

• Natural climate cycles

• Increased carbon dioxide from human activities

How does carbon dioxide contribute to global warming?

• It increases the Earth's albedo

• It absorbs heat and prevents it from escaping the atmosphere

• It reflects sunlight away from Earth

• It cools the Earth's surface

What is one potential consequence of global warming mentioned in the video?

• Increased biodiversity

• Rising sea levels

• Decreased rainfall

• More frequent earthquakes

What can individuals do to help reduce global warming?

• Increase fossil fuel consumption

• Cut down more trees

• Use more plastic products

• Reduce carbon dioxide emissions
