How gravity causes a perfectly spherical ball to roll down an inclined plane is part of the elementary school physics canon.

Earth's last ice age ended around 11,700 years ago and a new study predicts the next one should be 10,000 years away. But the researchers say record rates of fossil fuel burning that are increasing ...

New findings indicate that Mars' past conditions may have supported microbial life. Research draws parallels with extremophiles—microorganisms that thrive in extreme environments on Earth ...

Natural cycles in Earth's rotational axis and its orbit around the sun drive climatic changes, and now researchers have matched up specific points in those cycles to the timing of ice ages.

Earth's history is a roller-coaster of climate fluctuations, of relative warmth giving way to frozen periods of glaciation before rising up again to the more temperate climes we experience today.

A new study published last week is giving us a better idea. The research builds on previous hypotheses theorizing that Ice Ages occur on a predictable timeline that relates to the geometry of ...

Transitions between glacial and interglacial periods matched up with small variations in the shape of the Earth's orbit of the sun — how the Earth ‘wobbles' in space — and the angle of the ...
