If the oceans warm sufficiently through global warming, the methane on the ocean floor may become unstable, instigating a potentially catastrophic positive feedback to global warming (between the Triassic and Jurassic periods, about half of all life on earth went extinct, probably due to this drastic and sudden climate change).
The main focus of this research is to reduce the risk of a catastrophic response of a feedback control system when some of the feedback data from the system sensors are not reliable, while maintaining a reasonable performance of the control system.
It causes irreparable harm to senior citizens and the fear of falling reduces senior citizen mobility drastically, creating a feedback loop that can be catastrophic.
Even a slight disturbance of specific pathway intermediates, such as seen in the Pex11beta knockout mouse, could trigger a catastrophic regulatory response that escalates by inappropriate activation of feedback loops.
Across all, positive feedback mechanisms shift seemingly stable system phenomena towards complexity and catastrophic, far-from-equilibria conditions (Thom 1977; Cambel 1993; Arthur 1994a, b;).
Scientists describe "catastrophic climate change" as the point at which the earth warms enough to trigger feedback cycles that will contribute to runaway warming.
A meter measuring the phase shift across this interphase is analogous to a thermometer reporting the temperature, thereby providing feedback for rapid corrections of any operating conditions that might lead to the catastrophic destruction of the cell.
Another example is the gene regulatory feedback loop required for endoderm specification in echinoderms, which encodes several transcription factors whose inactivation has catastrophic effects on the entire body plan [ 17, 22].
The strong positive bioclimatic feedback lends strong evidence that TC effects can be largely beneficial for some species, which refutes some generalist catastrophic assessments about TC on ecosystems [42], [43].
A catastrophic, terrible loss.
