Change in the earth's orbit?

In summary, the earth's orbit changes over time due to factors such as gravitational pull, tilt of the axis, and distribution of mass. These changes can impact climate by affecting sunlight and heat, potentially leading to ice ages. These changes occur constantly but have significant effects over long periods of time, which can be studied through various methods such as data analysis and observation.

last night i was watching a public broadcasting special about climate change, and they mentioned that 125,000 years ago there was a large peak in CO2 in the atmosphere which caused a rise in global temp. they stated that the effect was caused by a "change in the Earth's orbit around the sun."

what happened 125,000 years ago that would have caused a change in the Earth's orbit significant enough to affect the global climate? thanks.

thanks DH - that helped.
 

1. How does the earth's orbit change over time?

The earth's orbit changes over time due to various factors such as the gravitational pull of other planets, the tilt of the earth's axis, and the distribution of mass within the solar system. These changes can cause the earth's orbit to become more elliptical or circular, and can also affect the length of the earth's orbital period.

2. What is the impact of changes in the earth's orbit on climate?

Changes in the earth's orbit can have a significant impact on climate, as they can affect the amount of sunlight and heat that reaches the earth's surface. For example, when the earth's orbit is more elliptical, the earth receives more solar radiation and experiences warmer temperatures. This can lead to changes in weather patterns and affect the growth and distribution of plants and animals.

3. How often does the earth's orbit change?

The earth's orbit is constantly changing, but the most significant changes occur over long periods of time. For example, the earth's orbit goes through cycles of eccentricity, which can last for thousands of years. Additionally, the earth's tilt and precession also go through cycles that can last for tens of thousands of years.

4. Can changes in the earth's orbit cause ice ages?

Yes, changes in the earth's orbit are one of the factors that can contribute to ice ages. When the earth's orbit is more elliptical, it receives more solar radiation and can lead to warmer temperatures. However, when the orbit is more circular, the earth receives less solar radiation and can result in cooler temperatures and potentially trigger an ice age.

5. How do scientists study changes in the earth's orbit?

Scientists study changes in the earth's orbit through various methods, such as analyzing geological and ice core data, studying the movement of celestial bodies, and using computer models to simulate past and future changes. They also use tools such as satellites and telescopes to observe and measure the earth's orbit and its effects on climate and other natural phenomena.
