Sentences with phrase «planetary scale change»

There are probably no quantitative planetary scale changes with an effect.

Not exact matches

The effect also illustrates one proposal for so - called geoengineering — the deliberate, large - scale manipulation of the planetary environment — that would use various means to create such sulfuric acid aerosols in the stratosphere to reflect sunlight and thereby hopefully forestall catastrophic climate change.

Industrial scale «biochar» is the latest dangerous planetary geoengineering proposal to save the Earth and humanity from climate change without personal sacrifice or social change.

We have a unique opportunity at this moment in our human history, to become positive change agents on a planetary scale.

«Global climate change is a security issue on a planetary scale,» Kerry told Grist in 2007.

The Planetary Boundaries framework proposes quantitative limits for human perturbation of critical Earth system processes, and a «safe operating space» within which human activity should attempt to stay in order to avert the risk of large - scale, possibly abrupt or irreversible environmental change.

The impacts of climate change are becoming more frequent and devastating [1], and the world's leading scientists have issued stark warnings about the scale of the planetary emergency.

And although «weather improvement» is not quite the same thing as «solving» climate change — here we get to a big parallel with the more globally ambitious forms of geoengineering, especially the SRM techniques that seek to create a compensating cooling effect on a planetary scale: they are (likely) much cheaper than emissions reductions.

Professor Solomon Hsiang and colleagues described in the journal Nature in 2011 how they had investigated whether anything linked «planetary - scale climate changes with global patterns of civil conflict».

We downscale four planetary boundaries (climate change, land - system change, freshwater use and biogeochemical flows) to per capita equivalents, and compare these to footprint indicators at the national scale.

Tropospheric climate changes will also alter planetary - scale waves.

Ozone changes could affect stratospheric winds so that breaking of vertically propagating planetary - scale Rossby waves from the troposphere would be affected, this breaking could drive the downward propagation of NAM - like patterns which would ultimately be seen in the SAT.

Welcome to «geo - engineering», which holds that, rather than trying to change mankind's industrial habits, it is more efficient to counter the effects, using planetary - scale engineering.

We find that an increase in poleward heat transport by the tropical ocean results in a warming of the extra-tropics, relatively little change in the tropical temperatures, moistening of the subtropical dry zones, and partial but incomplete compensation of the planetary - scale energy transport by the atmosphere.
