Understanding Milankovic Cycles and their Impact on Earth's Climate
TLDR Milankovic cycles, which include variations in the Earth's tilt, axial procession, and orbital eccentricity, have a significant impact on the long-term climate of the Earth, including the patterns of ice ages and the amount of sunlight that falls on the northern hemisphere. However, they are not responsible for recent climatic changes observed in the last several decades.
Timestamped Summary
00:00
Milankovic cycles can interact with each other and affect the long-term climate of the Earth.
01:29
Milankovic cycles involve understanding the different cycles that the Earth goes through, including the tilt of the Earth known as obliquity, which wobbles between 22.1 degrees and 24.5 degrees over a 41,000 year cycle.
02:54
The Earth goes through cycles of axial procession and orbital eccentricity, which affect the tilt of the Earth's axis and the shape of its orbit around the sun.
04:21
Mula Ten Milankovic discovered that cycles of axial tilt, eccentricity, and precession closely follow the patterns of ice ages and affect the amount of sunlight that falls on the northern hemisphere.
05:44
The amount of sunlight falling on the northern hemisphere in the summer is crucial for ice accumulation and melting during ice ages.
07:02
Milankovic cycles are not responsible for recent climatic changes measured over the last several decades.
08:19
The Earth's spinning and orbit are constantly changing, with cycles within cycles.
