Climate Change and Its Effects

The video discusses climate change, focusing on the carbon cycle, global temperature trends, and the impact on weather patterns and ice melting. It highlights the importance of understanding the basics to grasp climate change, the uneven warming of the Earth, and the resulting changes in weather patterns, such as increased droughts and hurricanes. The video also covers the melting of glaciers and sea ice, emphasizing the ecological impacts and the role of ice in regulating Earth's temperature.

What is the primary reason for the increase in carbon dioxide levels in the atmosphere?

• Deforestation

• Burning of fossil fuels

• Volcanic eruptions

• Solar flares

Why do scientists prefer the term 'climate change' over 'global warming'?

• To emphasize the uneven warming across the globe

• Because global warming is not happening

• To avoid confusion with weather changes

• Because it sounds more scientific

What is the significance of the anomaly in global temperature measurements?

• It indicates the difference from the average

• It shows the exact temperature

• It measures only the coldest years

• It predicts future temperatures

How does the increase in global temperature affect weather patterns?

• It reduces the frequency of storms

• It stabilizes the climate

• It leads to more droughts and rainfall

• It causes more consistent weather

What is a major effect of increased evaporation in deserts?

• More rainfall in deserts

• Decreased temperatures

• Stable desert climates

• Increased desertification

What fuels hurricanes, making them more frequent and severe?

• Mountain ranges

• Cold air currents

• Warm water

• High pressure systems

What is a significant consequence of melting glaciers?

• Decreased global temperatures

• More freshwater availability

• Rising sea levels

• Increased land for agriculture

What role does sea ice play in regulating Earth's temperature?

• It absorbs solar radiation

• It reflects solar radiation

• It decreases ocean salinity

• It increases atmospheric pressure

How does the melting of Arctic ice affect polar bears?

• It shrinks their habitat

• It expands their habitat

• It has no effect on them

• It increases their food supply

What is the impact of uneven growth in Antarctica?

• It affects marine life habitats

• It balances the melting Arctic ice

• It increases global temperatures

• It decreases sea levels
