Let's break down each statement one by one:

1. **Earth is currently in an intergalactic period**: **False**. Earth is not in an "intergalactic period." It is in the Milky Way galaxy and is not experiencing any recognized "intergalactic" stage.

2. **Climate has changed naturally over Earth's history**: **True**. The climate has undergone significant natural changes over geological time due to various factors such as volcanic activity, changes in solar radiation, plate tectonics, and natural variations in greenhouse gases.

3. **Atmosphere composition has remained constant throughout Earth's history**: **False**. The composition of Earth’s atmosphere has changed considerably over geological time due to biological processes, volcanic activity, and other factors. For example, the levels of oxygen and carbon dioxide have varied widely.

4. **The increasing carbon dioxide since the year 1860 is similar to the past increase**: **False**. While carbon dioxide levels have fluctuated in the past, the rapid increase seen since the Industrial Revolution (around 1860) is much more pronounced and is mainly attributed to human activities, such as burning fossil fuels and deforestation, rather than natural processes.

In summary:
1. False
2. True
3. False
4. False
