Land rising above the sea 2.4 billion years ago changed planet Earth
Chemical signatures in shale, the Earth's most common sedimentary rock, point to a rapid rise of land above the ocean 2.4 billion years ago that possibly triggered dramatic changes in climate and life.

Study gives first proof that the Earth has a natural thermostat
New data provides the first proof that the Earth has a natural thermostat which enables the planet to recover from extremes of climate change - but the recovery timescales are significant. This work is presented today at ...

Weathering of rocks a poor regulator of global temperatures
A new University of Washington study shows that the textbook understanding of global chemical weathering—in which rocks are dissolved, washed down rivers and eventually end up on the ocean floor to begin the process again—does ...

Battered Earth revived by mineral weathering after mass extinction
Earth's bedrock was severely beaten by hothouse climate conditions during one of the planet's mass extinctions some 200 million years ago. But the process also allowed life to bounce back.

Climate cycles may explain how running water carved Mars' surface features
Dramatic climate cycles on early Mars, triggered by buildup of greenhouse gases, may be the key to understanding how liquid water left its mark on the planet's surface, according to a team of planetary scientists.

Weathering of rocks by mosses may explain climate effects during the Late Ordovician
During the Ordovician period, the concentration of CO2 in the earth's atmosphere was about eight times higher than today. It has been hard to explain why the climate cooled and why the Ordovician glaciations took place. A ...

Chemical weathering controls erosion rates in rivers
Chemical weathering can control how susceptible bedrock in river beds is to erosion, according to new research. In addition to explaining how climate can influence landscape erosion rates, the results also may improve scientists' ...

Weathering and river discharge surprisingly constant during Ice Age cycles
Over geologic time, the work of rain and other processes that chemically dissolve rocks into constituent molecules that wash out to sea can diminish mountains and reshape continents.
