Scientists have long debated what causes glacial/interglacial cycles, which have occurred most recently at intervals of about 100,000 years. A new study reported in the March 24 issue of Nature finds ...

Milutin Milankovitch hypothesized that the timing of glacial transitions has been controlled by the orbital parameters of the Earth, which suggests that there may be some predictability in the climate ...

A research team, composed of climatologists and an astronomer, have used an improved computer model to reproduce the cycle of ice ages (glacial periods) 1.6 to 1.2 million years ago. The results show ...

Marine scientists have discovered that what was once thought to be a single sea slug species is actually at least 75 distinct species that were shaped over millions of years by repeated Antarctic ...

Beginning around 2.5 million years ago, Earth entered an era marked by successive ice ages and interglacial periods, emerging from the last glaciation around 11,700 years ago. A new analysis suggests ...

These ancient cores may contain clues about an unexplained change in Earth’s glacial-interglacial cycles, and could shed light on how human-generated emissions will shape our planet’s future. Reading ...

The study of paleoclimate dynamics and glacial cycle mechanisms seeks to understand how Earth’s climate has varied over geological time and what drives the alternation between ice‐age (glacial) and ...

Giant viruses defy microbiological norms Lead author Laura Perini and her team at the Department of Environmental Science at ...

A research team, composed of climatologists and an astronomer, have used an improved computer model to reproduce the cycle of ice ages (glacial periods) 1.6 to 1.2 million years ago. The results show ...

Proxy data – indirect records of the Earth’s climate found in unlikely places like coral, pollen, trees, and sediments – show interesting oscillations approximately every 100,000 years starting about ...
