What to include

  • Distinguish weather and climate by place and period.
  • Calculate a fictional anomaly series and bounded endpoint rate.
  • Compare independent indicators without deleting gaps or discrepancies.
  • Trace incoming solar and outgoing infrared pathways.
  • Explain mitigation and adaptation mechanisms and limits.
  • Write a sourced brief separating real background from practice data and complete changed cases.

Review and revise

Use these criteria to check your work and choose what to improve.

  • Method: applies the course-specific rules to the supplied cases with visible intermediate work.
  • Accuracy: results agree with the stated facts, units, boundaries and independent checks.
  • Reasoning: explains why the result follows and identifies a limitation or unresolved question.
  • Transfer: completes changed cases and revises the final project when a relevant assumption changes.
Three ideas to help you along the way
Three useful ideas

The rules behind the steps.

01

Read the specific conditions

Weather describes short-term atmospheric conditions; climate describes longer-term patterns and variation over a defined region and period, often using 30-year summaries. One unusually cold day does not determine a long-term trend. Local records and global averages answer different questions.

02

Connect the mechanism

A stronger climate assessment uses multiple records measuring different parts of the system, such as surface temperature, ocean heat, ice and sea level. Converging indicators can support a shared explanation, while their units and mechanisms differ. A single invented exercise record is not itself real-world evidence.

03

Explain evidence and limits

A sound brief separates actual sourced scientific background, labeled practice calculations and a bounded local question. Explain uncertainty without treating every uncertainty as absence of knowledge. Sources support the claims they actually address; a global trend does not alone identify the cause of one local event.

What do these words mean?
Key words

Key terms worth knowing.

Weather
Short-term atmospheric conditions at a place.
Climate
Longer-term patterns and variation over a defined place and period.
Anomaly
Difference from a stated baseline average.
Greenhouse effect
Atmospheric absorption and emission of infrared energy that changes heat transfer.
Mitigation
Action addressing climate-change causes such as emissions.
Adaptation
Adjustment addressing impacts and vulnerability.
