“Social tipping points” in a dryland pastoral system in Namibia

Pastoralism
Critical transitions in ecosystems occur when a “tipping point” is crossed, resulting in an abrupt shift to a new stable state that is almost impossible, to reverse.

Environmental tipping points and food system dynamics: Main report [PDF]

, 2017
First paragraph: Environmental tipping points occur when there are step changes in the way the biophysical world works – whether loss of soil fertility, collapse of a fishing stock, or sudden changes in weather patterns, such as those that caused ...

Systemic contributions to global catastrophic risk

Global Sustainability
Non-technical summary We live in a time of significant global risk. Some research has focused on understanding systemic sources of this risk, while other research has focused on possible worst-case outcomes.

ESD Ideas: Climate tipping is not instantaneous – the duration of an overshoot matters [PDF]

Earth System Dynamics
Climate tipping points are not committed to occur automatically upon crossing critical thresholds in global warming, as is often assumed. Instead, it is possible to temporarily overshoot a threshold without causing tipping, provided the duration of the ...

The implications of overshooting 1.5 °C on Earth system tipping elements—a review

Environmental Research Letters
Due to insufficient emission reductions in recent years, it is increasingly likely that global warming will exceed the 1.5 °C temperature limit in the late 2020s or 2030s.

The “NO” tipping point [PDF]

Blood, 2007
[Comment on Hsu et al, page 3088][1]Pulmonary hypertension in sickle cell anemia, an important risk factor for early mortality, may be caused by intravascular hemolysis leading to decreased NO bioavailability.

“History in a bottle”: tipping dynamics in packaging systems – the case of how a bottle reuse system was established and then undone [PDF]

Earth System Dynamics
In this paper, we investigate the initially successful transition from regional bottle reuse for mineral water to a widespread bottle reuse system in Germany, along with its subsequent destabilisation into a single-use recycling paradigm, and what this ...

The interaction of solar radiation modification with Earth system tipping elements [PDF]

Earth System Dynamics
The avoidance of hitting tipping points has been invoked as a significant benefit of solar radiation modification (SRM) techniques; however, the physical science underpinning this has thus far not been comprehensively assessed.
