Climate Change and Its Impacts

Human activities are increasing Earth's temperature through the greenhouse effect, primarily due to the burning of fossil fuels, which has raised CO2 levels significantly since the industrial revolution. This has led to climate change, affecting oceans, weather, food sources, and health. Ice sheets are melting, causing sea levels to rise, and extreme weather events are becoming more frequent. Climate change also impacts human health by increasing smog levels, leading to respiratory and cardiovascular diseases. However, by transitioning to renewable energy sources, we can mitigate some of these effects.

What is the primary cause of the greenhouse effect?

• Solar flares

• Ozone layer depletion

• Greenhouse gases trapping heat

• Deforestation

Since the industrial revolution, by how much has the CO2 level increased in the atmosphere?

• By a third

• By a quarter

• By double

• By half

What is one of the major consequences of ice sheets melting?

• Decrease in global temperatures

• Rise in sea levels

• Increase in forest areas

• Reduction in air pollution

How does climate change affect weather patterns?

• It stabilizes global temperatures

• It makes weather more predictable

• It reduces the frequency of storms

• It causes more extreme weather events

What challenge does climate change pose to agriculture?

• More frequent droughts

• Easier pest control

• Increased crop yields

• Longer growing seasons

What health issues can be exacerbated by increased smog levels?

• Diabetes

• Asthma and lung cancer

• Arthritis

• Vision problems

What is the effect of higher temperatures on smog levels?

• Smog levels decrease

• Smog levels remain the same

• Smog levels increase

• Smog levels are unaffected

What is a significant way humans can combat climate change?

• Increasing fossil fuel usage

• Transitioning to renewable energy

• Building more factories

• Cutting down more forests

Which renewable energy sources are mentioned as alternatives to fossil fuels?

• Hydropower and biomass

• Nuclear and geothermal

• Coal and natural gas

• Solar and wind

What is the role of humans in addressing climate change?

• Humans should ignore it

• Humans can combat it by reducing emissions

• Humans can only adapt

• Humans have no role
