Climate Change and Its Effects

The video explores the effects of climate change, focusing on global warming, its impact on weather patterns, ecosystems, and sea levels. It discusses ocean acidification due to increased CO2 and the concept of positive feedback loops, which exacerbate climate change. The video highlights the urgent need to address these issues to mitigate further environmental damage.

What is the primary cause of the planet's warming as discussed in the video?

• Increased solar activity

• Volcanic eruptions

• Release of extra greenhouse gases

• Deforestation

How might climate change affect rainfall patterns?

• All regions will experience droughts

• Rainfall will remain constant everywhere

• Some areas will have more rain, others less

• Rainfall will only increase in polar regions

What is one way that ecosystems are adapting to climate change?

• Marine life is moving to freshwater

• Crops like sunflowers are replacing traditional ones

• Animals are migrating to urban areas

• Forests are expanding into deserts

What happens to sea levels when ice in mountain glaciers melts?

• Sea levels decrease

• Sea levels remain unchanged

• Sea levels fluctuate

• Sea levels rise

Why does melting Arctic ice not contribute to sea level rise?

• It evaporates before reaching the ocean

• It turns into water vapor

• It is already floating and displaces its own volume

• It is absorbed by the land

What effect does increased carbon dioxide have on ocean water?

• It makes the water more alkaline

• It has no effect on the water

• It makes the water more acidic

• It increases the water's temperature

What is a consequence of ocean acidification on marine life?

• Marine plants are unaffected

• Coral reefs are dying

• Coral reefs are thriving

• Fish populations are increasing

What is an example of a positive feedback loop in climate change?

• Melting ice leads to more heat absorption

• Melting ice reflects more sunlight

• Ice melting leads to more ice formation

• Ice melting has no effect on temperature

What happens when methane is released from melting northern marshy regions?

• It reduces greenhouse gases

• It has no effect on the atmosphere

• It contributes to further warming

• It cools the atmosphere

What is the overall impact of global warming as summarized in the video?

• It has no significant impact

• It is causing more storms, floods, and droughts

• It is beneficial for all ecosystems

• It only affects polar regions
