Understanding Global Warming

The Earth's climate has fluctuated over millions of years, but recent human activities have accelerated global warming. The burning of fossil fuels has increased greenhouse gases, enhancing the greenhouse effect and causing temperatures to rise. Evidence includes record warm years and shrinking Arctic ice. If fossil fuel use continues, temperatures could rise significantly, leading to severe environmental consequences. However, reducing emissions and conserving energy can mitigate these effects.

What has been the trend in Earth's temperature over the last century?

• It has remained constant.

• It has decreased slightly.

• It has risen unusually fast.

• It has fluctuated randomly.

What major event marked the beginning of significant fossil fuel use?

• The Agricultural Revolution

• The Renaissance

• The Industrial Revolution

• The Information Age

How do greenhouse gases affect the Earth's temperature?

• They have no effect on temperature.

• They absorb all sunlight, causing darkness.

• They trap heat, warming the Earth.

• They cool the Earth by reflecting sunlight.

Which year was reported as the warmest in measured history?

• 2005

• 1998

• 2010

• 2015

What has happened to the Arctic sea ice over the last 30 years?

• It has disappeared completely.

• It has decreased by 10%.

• It has remained the same.

• It has increased by 10%.

What is a potential consequence of rising global temperatures?

• Stable weather patterns

• More frequent hurricanes

• Decreased sea levels

• Increased polar ice

How can individuals help reduce the impact of global warming?

• By conserving energy at home

• By increasing greenhouse gas emissions

• By using more fossil fuels

• By cutting down more trees

What is one way governments can help mitigate global warming?

• By increasing greenhouse gas emissions

• By cutting greenhouse gas emissions

• By promoting fossil fuel use

• By ignoring climate change

What could happen to animals that cannot adapt to changing climates?

• They will thrive and multiply.

• They could face extinction.

• They will migrate to colder regions.

• They will evolve new traits instantly.

What is a simple action consumers can take to help the environment?

• Drive more miles each week

• Use more energy-intensive appliances

• Use energy-efficient light bulbs

• Leave lights on when not needed
