Geological archives may predict our climate future
By analyzing 56-million-year-old sediments, a UNIGE team has measured the increase in soil erosion caused by global warming, synonymous with major flooding.

Throughout the past 500 million years, our planet has experienced a total of five mass extinctions. One of these—the Permo-Triassic mass extinction event—led to the demise of roughly 90% of Earth's species.

Modeling of Earth's response to global warming has suggested dry regions will become more arid and wet regions will experience more precipitation, with an uneven distribution of moisture in the atmosphere. With enhanced seasonality, ...
Monsoons are seasonal climate conditions resulting from changes in wind that bring extreme drought or rain, depending upon the time of year. Those occurring in south Asia and east Asia are affected by a combination of atmospheric ...

The Eocene (symbol EO) Epoch, lasting from about 56 to 34 million years ago (55.8±0.2 to 33.9±0.1 Ma), is a major division of the geologic timescale and the second epoch of the Paleogene Period in the Cenozoic Era. The Eocene spans the time from the end of the Palaeocene Epoch to the beginning of the Oligocene Epoch. The start of the Eocene is marked by the emergence of the first modern mammals. The end is set at a major extinction event called Grande Coupure (the "Great Break" in continuity), which may be related to the impact of one or more large bolides in Siberia and in what is now Chesapeake Bay. As with other geologic periods, the strata that define the start and end of the epoch are well identified, though their exact dates are slightly uncertain.
The name Eocene comes from the Greek ἠώς (eos, dawn) and καινός (kainos, new) and refers to the "dawn" of modern ('new') mammalian fauna that appeared during the epoch.
