China's snow..decoupling is an issue..

Physics
In physics, decoupling is the general phenomenon in which the interactions between some physical objects (such as elementary particles) disappear.
Biology
In biology, decoupling (used interchangeably with uncoupling) refers to the separation of the energy stored in the ion gradients inside mitochondria from the synthesis of ATP
[edit] Mathematics
In mathematics, decoupling refers to the rearrangement of systems of equations so that they are independent of each other.
Economics
In economics, decoupling refers to the lessening of correlation or dependency between variables. It is often used in the context of economic production and environmental quality. In this context, it refers to the ability of an economy to grow without corresponding increases in environmental pressure. In many economies increasing production (GDP) would involve increased pressure on the environment. An economy that is able to sustain GDP growth, without also experiencing a worsening of environmental conditions, is said to be decoupled. Exactly how, if, or to what extent this can be achieved is a subject of much debate.
