Social Studies: Climate Change: Evidence and Policy Worksheet

Question 1

Define climate change in your own words. Then explain the difference between weather and climate.

Accepted Answer

Climate change is a long-term shift in average temperature, precipitation, and other patterns in Earth's climate system. Weather describes short-term conditions such as today's temperature or a storm this week, while climate describes average patterns over many years or decades.

Question 2

List two types of evidence scientists use to show that Earth's climate is warming. For each one, explain what it shows.

Accepted Answer

Scientists use long-term temperature records and ice core data as evidence. Temperature records show that average global temperatures have increased over time, and ice cores show past atmospheric conditions, including greenhouse gas levels, that help compare current warming to earlier periods.

Question 3

A graph shows atmospheric carbon dioxide rising from about 315 parts per million in 1960 to over 420 parts per million today. What conclusion can you draw from this trend, and why does it matter for climate policy?

Accepted Answer

The graph shows that atmospheric carbon dioxide has increased substantially over time. This matters for climate policy because carbon dioxide is a greenhouse gas that traps heat, so rising levels support policies aimed at reducing emissions and limiting future warming.

Question 4

Explain how the greenhouse effect works. Then describe how human activities can strengthen it.

Accepted Answer

The greenhouse effect happens when gases in the atmosphere trap some of the heat that Earth radiates back into space. Human activities such as burning fossil fuels, cutting forests, and some agricultural practices increase greenhouse gas concentrations, which strengthens this heat-trapping effect.

Question 5

Identify one economic impact and one social impact of climate change on a community. Explain each with a specific example.

Accepted Answer

One economic impact is damage to infrastructure from stronger floods or storms, which can force a city to spend large amounts on repairs. One social impact is displacement of residents after repeated disasters, which can interrupt schooling, employment, and access to healthcare.

Question 6

Compare mitigation and adaptation. Give one example of each climate policy.

Accepted Answer

Mitigation means reducing the causes of climate change, while adaptation means adjusting to its effects. An example of mitigation is a policy that expands renewable energy use, and an example of adaptation is building seawalls or improving flood drainage systems.

Question 7

A city is choosing between two policies: Policy A gives tax credits for solar panels, and Policy B updates building codes to require better flood protection. Which policy is mainly mitigation, which is mainly adaptation, and why?

Accepted Answer

Policy A is mainly mitigation because it encourages cleaner energy and can lower greenhouse gas emissions. Policy B is mainly adaptation because it prepares buildings and residents for the impacts of flooding that are already happening or becoming more likely.

Question 8

Why do climate change policies sometimes create political disagreement? Give two reasons based on social studies themes such as economics, government power, or public values.

Accepted Answer

Climate policies can create political disagreement because people may disagree about the economic costs and benefits of regulations, taxes, or energy transitions. They may also disagree about how much power governments should have to set rules, how quickly changes should happen, or which values should guide decisions.

Question 9

Describe one reason why international cooperation is important in addressing climate change.

Accepted Answer

International cooperation is important because greenhouse gas emissions and climate impacts cross national borders. If countries work together on emissions goals, technology sharing, and finance, they can have a greater overall effect than acting alone.

Question 10

Read this claim: 'Climate policy should focus only on the future, not on current inequalities.' Write a short response agreeing or disagreeing and support your answer with one reason.

Accepted Answer

A strong response would disagree and explain that current inequalities matter because low-income communities and some nations often face greater risks and have fewer resources to recover from climate impacts. Effective climate policy should consider both future protection and present-day fairness.

Question 11

What is one role citizens can play in shaping climate policy in a democracy? Explain how that action can influence decision-makers.

Accepted Answer

Citizens can vote for candidates and ballot measures that support their climate policy priorities. Voting can influence decision-makers because elected officials respond to public opinion and may change laws, budgets, or regulations based on voter preferences.

Question 12

A state government is deciding whether to invest public money in public transit, wildfire prevention, and coastal protection. Choose one of these and argue why it should be a priority using evidence-based reasoning.

Accepted Answer

A strong response will choose one option and support it with evidence-based reasoning. For example, coastal protection could be a priority if rising sea levels and stronger storms threaten homes, roads, and businesses, while public transit could be prioritized if the state needs to reduce emissions and improve transportation access.
