There has long been debate about the role of Earth’s orbit in driving global climate cycles. As most people know, 90,000 of every 100,000 years have been ice ages in patterns.
Scientists have long been aware that the waxing and waning of massive Northern Hemisphere ice sheets results from changes in the geometry of Earth’s orbit around the Sun.
A new study has been able to pinpoint exactly how the tilting and wobbling of the Earth as it orbits around the Sun has influenced the melting of ice sheets in the Northern Hemisphere over the past 2 million years.
