Let's evaluate each statement one by one:
1. **Earth is currently in an interglacial period.** - **True**. The Earth is currently in the Holocene epoch, which is an interglacial period that began approximately 11,700 years ago after the last glacial period.
2. **Climate has changed naturally over Earth's history.** - **True**. The Earth's climate has indeed changed naturally over millions of years due to factors like volcanic activity, variations in solar radiation, tectonic plate movements, and orbital changes (Milankovitch cycles).
3. **Atmosphere composition has remained constant throughout Earth's History.** - **False**. The composition of the Earth's atmosphere has changed significantly over geological time due to processes such as photosynthesis, volcanic activity, and the evolution of life.
4. **The increase in carbon dioxide since the year 1860 is similar to past increases.** - **False**. The rate of increase in carbon dioxide levels since the Industrial Revolution (around 1860) is unprecedented on geological timescales. While there have been past increases in CO2, the current rate is significantly faster and tied to human activities.
So, to summarize:
1. True
2. True
3. False
4. False
