Toy gyroscopes can do all kinds of interesting tricks. The most mysterious one, precession, seems to defy gravity. By definition, precession refers to a change in the orientation of the rotational ...

Glacial cyclicity of the Earth has often been considered on 100,000 year timescales, particularly for the Late Pleistocene (~11,700 to 129,000 years ago) swapping between periods of extensive polar ...

The Earth’s climate is a dynamic entity, continuously evolving over billions of years with alternating periods of extreme heat and cold. Recent scientific studies indicate that the Earth is subtly ...

Scientists have finally put to bed a long-standing question over the role of Earth’s orbit in driving global ice age cycles. In a new study published today in the journal Science, the team from ...

According to our best understanding of Earth’s climate, the global average temperature has increased significantly over the past ~140 years: the amount of time for which a reliable, direct temperature ...

A: Astronomers call the wobble of Earth’s axis precession. While most of us are familiar with our planet’s primary motions — rotation (spinning once a day) and revolution (orbiting the Sun once a year ...

Climate can change fast, even when the planet looks stable. Earth has flipped into new patterns within decades in the past. During the last Ice Age, Greenland warmed by as much as 16°C over short ...

Earth’s magnetic field is generated by fluid motions in the outer core. This geodynamo has operated for over 3.4 billion years. However, the mechanism that has sustained the geodynamo for over 75% of ...
