Climate Change
What is it?
Greenhouse gases absorb outgoing infrared radiation. Human-driven increases strengthen the greenhouse effect, altering temperature, rainfall, oceans and species distributions.
In simple words
- Greenhouse gases absorb outgoing infrared radiation. Human-driven increases strengthen the greenhouse effect, altering temperature, rainfall, oceans and species distributions.
- Understanding climate change connects structure, mechanism and biological outcome. It helps explain how a change at one level can affect the whole organism, population or environment.
- A complete answer on climate change links the starting condition to its mechanism and outcome.
Important terms
Climate change: Greenhouse gases absorb outgoing infrared radiation. Human-driven increases strengthen the greenhouse effect, altering temperature, rainfall, oceans and species distributions.
Mechanism: Start with the trigger or starting condition, follow the biological structures and signals in order, and finish with the response or product. For climate change, the central relationship is: Greenhouse gases absorb outgoing infrared radiation. Human-driven increases strengthen the greenhouse effect, altering temperature, rainfall, oceans and species distributions.
Biological significance: Understanding climate change connects structure, mechanism and biological outcome. It helps explain how a change at one level can affect the whole organism, population or environment.
What you should learn
- Define climate change in accurate biological language.
- Explain the mechanism or relationship involved in climate change.
- Apply climate change to a comparison, prediction or Federal Board exam question.
Examples
- Identify the starting condition
- Name the active structure or molecule
- Trace the direction of change
CORE CONCEPT

Full school-level explanation
Greenhouse gases absorb outgoing infrared radiation. Human-driven increases strengthen the greenhouse effect, altering temperature, rainfall, oceans and species distributions.
Build the idea from concept to mechanism:
WHAT — CLIMATE CHANGE
Greenhouse gases absorb outgoing infrared radiation. Human-driven increases strengthen the greenhouse effect, altering temperature, rainfall, oceans and species distributions.
WHY — Why it matters
Understanding climate change connects structure, mechanism and biological outcome. It helps explain how a change at one level can affect the whole organism, population or environment.
HOW — How to explain it
Start with the trigger or starting condition, follow the biological structures and signals in order, and finish with the response or product. For climate change, the central relationship is: Greenhouse gases absorb outgoing infrared radiation. Human-driven increases strengthen the greenhouse effect, altering temperature, rainfall, oceans and species distributions.
CORE CONCEPT
Greenhouse gases absorb outgoing infrared radiation. Human-driven increases strengthen the greenhouse effect, altering temperature, rainfall, oceans and species distributions.
Remember
- climate change
- accurate biological link
Examples
- Identify the starting condition
- Name the active structure or molecule
- Trace the direction of change
- State the final outcome
