One bid for preservation initiated in 2009 by 29 scientists from around the world focused on the concept of planetary boundaries.
More acreage was converted to growing crops between 1950 and 1980, than from 1700 to 1850, and arable land is one of nine «planetary boundaries» that scientists have identified — limits past which humanity should fear to tread.
Here, we revise and update the planetary boundary framework, with a focus on the underpinning biophysical science, based on targeted input from expert research communities and on more general scientific advances over the past 5 years.
A scientific framework in support of global sustainability, emerging from Earth system science and resilience research, is the recent concept of Planetary Boundaries (Rockström et al., 2009).
In 1961, he transformed his vision that the dominant color from this perspective would be blue, and that all man - made boundaries could be overcome with this color, into his series «Planetary Reliefs.»
To me it is astonishing that both of these posts seem to take us to task for not being aware of the «planetary boundaries» research (more on that below) when the central conclusion from that work is that real boundaries need to be set in multiple dimensions — exactly what we argue.
A diagram from a 2009 analysis of «planetary boundaries» showed humans were already hitting limits (red denotes danger zones).
A diagram from a paper defining «planetary boundaries» for human activities shows areas of greatest risk in red.
6:57 p.m. Addendum For relevant work with somewhat different conclusions review the presentations from «Intensifying agriculture within planetary boundaries,» a session at the Planet Under Pressure conference in London last March.
Dynamical upward transport by convection removes excess heat from the surface more efficiently than longwave radiation is able to accomplish in the presence of a humid, optically thick boundary layer, and deposits it in the upper troposphere where it is more easily radiated to space, thereby affecting the planetary energy balance.
If one or more of these boundaries is breached, environmental trajectories that veer from their natural path could impact planetary systems so severely that the very survival of the human species would be in jeopardy.
There is also a planetary boundary layer module that evaluates the turbulent transport of heat and water vapor from the ground surface into the atmosphere.
The planetary - boundaries group, which published a sort of manifesto in 2009, argues for increased restraint and, where necessary, direct intervention aimed at bringing all sorts of things in the Earth system, from the alkalinity of the oceans to the rate of phosphate run - off from the land, close to the conditions pertaining in the Holocene.
Despite his memorable description of the worst possible outcome of the Anthropocene as being «a Frankenstein planet stitched together by geological resurrection men» (p258), Morton's sympathies seem to lie closer to the Promethean scientists who seek to manage an unavoidable (and potentially even «good») Anthropocene, than with more precautionary scientists and environmentalists who use the term as a warning — a reason for humanity to pull back from scientifically identified «planetary boundaries» and lessen our interference.
We apply a globally uniform threshold to the AGCM, and model subgrid fluctuations in wind speed using information from the AGCM's parameterizations of the planetary boundary layer, along with dry and moist convection.
Häyhä, T., Lucas, P. L., van Vuuren, D. P., Cornell, S. E. & Hoff, H. From planetary boundaries to national fair shares of the global safe operating space — how can the scales be bridged?
«Even under best - case scenario conditions,» Hickel argued, «absolute decoupling of GDP growth from material use is not possible on a global scale,» and certainly is not enough to reduce material use sufficiently to stay within planetary boundaries.
Actually, it is astonishing to me that Victor cites the planetary boundaries research in his defense, when the central conclusion of that work from a self - described «group of 28 internationally renowned scientists» is that we are already past the planetary boundary for climate!
Our current method for extracting higher yields from land involves aggressive use of chemical fertilizers and pesticides, which have already pushed us well over the planetary boundaries for biogeochemical flows.
