Despite this conceptual slippage, considerations of known Earth system interactions across scales suggest the need for "extreme caution in approaching or transgressing any individual planetary boundaries." [3] Another example has to do with coral reefs and marine ecosystems: In 2009, researchers showed that, since 1990, calcification in the ...
A convective planetary boundary layer is a type of planetary boundary layer where positive buoyancy flux at the surface creates a thermal instability and thus generates additional or even major turbulence. (This is also known as having CAPE or convective available potential energy; see atmospheric convection.) A convective boundary layer is ...
The Doughnut, or Doughnut economics, is a visual framework for sustainable development – shaped like a doughnut or lifebelt – combining the concept of planetary boundaries with the complementary concept of social boundaries. [1] The name derives from the shape of the diagram, i.e. a disc with a hole in the middle.

Planetary science – The study of planets (including Earth), moons, and planetary systems (in particular those of the Solar System) and the processes that form them. Planetary geology – study of the geology of astronomical objects apparently in orbit around stellar objects; Selenography – study of the surface and physical features of the Moon
Vertical profiles of mean variables in convective boundary layer. Adapted from Stull 1988 An Introduction to Boundary Layer Meteorology page 13 (1) The Surface layer is a very shallow region close to the ground (bottom 5–10% of CBL). It is characterized by a superadiabatic lapse rate, moisture decrease with height and strong wind shear. [2]
Breaking Boundaries tells the story how humans are pushing Earth beyond the boundaries that have kept the planet stable for 10,000 years, following scientific journey of Rockström and his team's discovery of the nine planetary boundaries.
As new forms of planetary consciousness emerge, we must reassert that humans remain the architects of meaning and moral compass. Ethical Scaffolds for an Expanding Complexity
