The Last Ice Age and Its End

The last ice age, also known as the Pleistocene glaciation, ended around 11,700 years ago. This period of significant climate change marked the end of a prolonged period of ice sheet expansion and contraction.

Understanding the Relationship Between Orbital Changes and Ice Ages

The Earth’s orbit around the sun is not a perfect circle, which means its distance from the sun varies throughout the year. This variation affects the amount of solar energy the Earth receives, leading to changes in climate.

Understanding the Science Behind Ice Ages

Ice ages are periods of significant global cooling, resulting in the expansion of ice sheets and glaciers. The Earth’s climate is influenced by various factors, including changes in the planet’s orbit, volcanic eruptions, and human activities such as burning fossil fuels and deforestation. Scientists have identified several key factors that contribute to the onset of ice ages. • Changes in the Earth’s orbit, particularly the tilt of its axis and the shape of its orbit around the sun, play a significant role in determining the onset of ice ages.

Understanding the Impact of Human Activity on Climate Shifts

The relationship between human activity and climate shifts has long been a topic of debate among researchers. While some argue that human activity is the primary cause of climate shifts, others claim that natural factors are more significant.
