climate has changed naturally over earths history.
atmospheric composition has remained constant throughout earths history.
the increase in carbon dioxide since the year 1860 is similar to past increases.
earth is currently in an interglacial period.

Explanation:

• "Climate has changed naturally over Earth’s history": Earth's climate has undergone natural changes (e.g., ice ages, warming periods) due to factors like orbital changes, solar activity, etc. → TRUE.
• "Atmospheric composition has remained constant throughout Earth’s history": Earth's atmosphere has changed (e.g., early atmosphere had little oxygen, later oxygen increased due to photosynthesis) → FALSE.
• "The increase in carbon dioxide since the year 1860 is similar to past increases": The recent CO₂ increase (since 1860) is much faster and larger than natural past increases, driven by human activities → FALSE.
• "Earth is currently in an interglacial period": Interglacial periods are warm intervals between ice ages; we are in the Holocene interglacial → TRUE.

Answer:

TRUE:

• Climate has changed naturally over Earth's history.
• Earth is currently in an interglacial period.

FALSE:

• Atmospheric composition has remained constant throughout Earth's history.
• The increase in carbon dioxide since the year 1860 is similar to past increases.
