Climate Change and Its Impacts

The video explores Earth's climate history, highlighting temperature changes from the age of dinosaurs to the present. It discusses the role of greenhouse gases, particularly CO2, in climate change and the resulting impacts on global weather patterns. The video emphasizes the importance of reducing CO2 emissions and adopting sustainable practices to mitigate climate change effects.

What natural evidence do scientists use to estimate ancient climate trends?

• Ocean currents and tides

• Volcanic eruptions and earthquakes

• Fossil fuels and minerals

• Ice cores and tree rings

What was the general trend in global temperatures between 1880 and 1940?

• Temperatures fluctuated around a stable average

• Temperatures consistently decreased

• Temperatures remained constant

• Temperatures consistently increased

Which greenhouse gas is primarily responsible for the recent rise in global temperatures?

• Carbon dioxide

• Methane

• Nitrous oxide

• Ozone

What is the greenhouse effect?

• The process of plants growing in a controlled environment

• The trapping of heat in the Earth's atmosphere by greenhouse gases

• The reflection of sunlight by the Earth's surface

• The absorption of carbon dioxide by oceans

What is one predicted consequence of climate change on polar regions?

• Melting ice caps

• Increased snowfall

• Formation of new glaciers

• Decreased sea levels

How has climate change affected weather patterns?

• Weather patterns have become more extreme and unpredictable

• Weather patterns have remained unchanged

• Weather patterns have become less severe

• Weather patterns have become more predictable

What is one way communities can adapt to climate change?

• Adopting sustainable habits and technologies

• Ignoring the changes

• Moving to urban areas

• Relying solely on government intervention

What is a recommended approach to reducing CO2 emissions?

• Increasing fossil fuel usage

• Promoting plant-based diets and low-carbon transportation

• Building more coal power plants

• Encouraging deforestation

Why is it important to limit the increase in global average temperature?

• To allow communities time to adapt to environmental changes

• To prevent the extinction of all plant species

• To stop all natural disasters

• To ensure the survival of only marine life

What is a challenge in changing societal behaviors to reduce CO2 emissions?

• The simplicity of current technologies

• The abundance of renewable energy sources

• The complexity of altering existing systems

• Lack of awareness about climate change
