Let's break down each statement:
1. **Earth is currently in the evening intergalactic period** - **False**. The term "evening intergalactic period" does not reflect any scientifically recognized period in Earth's history. Earth is currently in the Holocene epoch, which is part of the Quaternary period.
2. **Climate has changed naturally over Earth history** - **True**. Earth's climate has changed naturally over geological time scales due to various factors, including volcanic activity, changes in solar radiation, and variations in Earth’s orbit.
3. **Atmosphere composition has remained constant throughout Earth history** - **False**. The composition of Earth's atmosphere has changed significantly over geological time, influenced by factors such as volcanic activity, the evolution of life, and the carbon cycle.
4. **The increasing carbon dioxide since the year 1860 is similar to the past increase** - **False**. While CO2 levels have fluctuated in the past, the current rapid increase in atmospheric CO2 since the Industrial Revolution is unprecedented in the context of Earth's recent geological history, particularly in terms of the rate of increase.
So, the answers are:
1. False
2. True
3. False
4. False
