While the Milankovitch Cycles operate on timescales far longer than human lifespans, their effects are always at play.

Climate change deniers inaccurately claim that Earth's rapidly rising temperatures are the mere product of natural cycles. Scientific experts have long explained that, although Earth does experience ...

We live in a rapidly warming world. Immense volumes of human-generated greenhouse gases are nudging Earth’s climate to a warmer and warmer state, further changing our planet as sea levels rise, living ...

Ancient horsetail plants produce water with unusual oxygen isotopes, offering scientists a new tool to reconstruct Earth’s climate history and understand humidity patterns from millions of years ago.

Coccolithophores, tiny planktonic architects of Earth’s climate, capture carbon, produce oxygen, and leave behind geological records that chronicle our planet’s history. European scientists are ...

A view of one part of the Paleontology collection in the Museum of Natural History, arranged by the addition of representative specimens from other parts of the three floors of fossils in the East ...

A 60-million year old fossil palm leaf from Alaska. A new study by researchers including Isabel Montañez at UC Davis has produced the most accurate chart to date of how Earth's temperature has changed ...

Over the last 485 million years, Earth has been both a lot colder and a lot hotter than once thought. A new temperature timeline that combines geologic data with computational simulations reveals a ...

A new study offers the most detailed glimpse yet into how Earth's surface temperature has changed over the past 485 million years. The data show that Earth has been and can be warmer than today -- but ...

New reconstructions of 540 million years of climate history show the planet tumbling between icehouse and hothouse states, revealing how rare and vulnerable our temperate moment is. Some 4 billion ...

Global warming, with its long summers and increasing number of droughts, is introducing a new climate in the Amazon ...
