... within the channel and mechanisms of floodplain formation and destruction are important causes. The question is which combinations of causes are (INUS) conditions for meandering. The channel-related causes are discussed first. The feedback mechanisms of the channel–floodplain complex require a systems...

... feedback loop between increasing global temperature, continental weathering rates, and CO 2 that has tended to limit Earth climate changes over geological time scales. Due to the rapid increase in atmospheric carbon concentrations, global average temperatures have increased by more than 1.2 °C since...

..., terrestrial plant environments may drive environmental change, which may, in turn, feed back on the plant community itself. One result of this plant–environment feedback over geological timescales is the convergent evolution of stable solutions to environmental problems ( Niklas 1994 , 1997...

..., in particular, the relative roles of external radiative forcing versus internal feedback processes, remain to date highly controversial. The Miocene climate optimum (ca. 16.9–14.7 Ma) represents the warmest interval of the Neogene period (e.g., Shackleton and Kennett, 1975 ; Flower and Kennett, 1994...

...) Kfs weakens the cloud albedo feedback mechanism, which increases climate sensitivity. These mechanisms offer an explanation as to why this otherwise benign mineral is correlated so strongly with mass extinction events: every Kfs-rich ejecta blanket corresponds to a severe extinction episode over...

... and effusion and seismicity rates within the plumbing system. These data document that (1) there was no direct feedback between eruptive dynamics and graben topography, and (2) graben formation is near instantaneous on tectonic time scales. These results challenge the overarching role ascribed to magma...

..., especially for winter, affected by a suite of strong feedbacks such as changes in sea-ice cover in the high latitudes. We present a synthesis of winter temperature and precipitation proxy data from the Atlantic seaboard of Europe, spanning from southern Iberia to the Arctic. Our data reveal distinct...

... events increase porosity by fracturing. The model therefore accounts for positive and negative feedbacks that modify slip behavior through the seismic cycle. The model produces temporal clustering of earthquakes in the seismic record of the Aleutian margin, which has well-documented along-strike...

... are changing rapidly, for example during the glacial–interglacial transitions of the last 1 million years, this direct relationship can appear temporarily disrupted due to the varying time-scales of the feedbacks that couple CO 2 and temperature together. CO 2 can drive climate change both as a primary...

... transfer of CO 2 to the atmosphere. Conversely, calcium sulfate deposition weakens greenhouse forcing, while the high depositional rates of evaporite giants may overwhelm the silicate weathering feedback, causing several degrees of planetary cooling. Non-steady-state evaporite dynamics and related...

... marsh area decreases the sediment availability in estuarine systems through changes in regional-scale hydrodynamics. This positive feedback between marsh disappearance and the ability of coastal bays to retain sediments reduces the trapping capacity of the whole tidal system and jeopardizes the survival...

The mass-balance constraints on the long-term carbon cycle provide a mechanism for linking how land plant evolution...

...James F. Kasting Earth's climate is buffered over long timescales by a negative feedback between atmospheric CO 2 level and surface temperature. The rate of silicate weathering slows as the climate cools, causing CO 2 to increase and warming the surface through the greenhouse effect. This buffering...

The type and amount of vegetation controls sediment export by modifying the relationship between precipitation and erosion. Vegetation also alters subsurface soil...
