Climate change in China

Definitions

P

Particulates

Tiny pieces of solid or liquid matter, such as soot, dust, fumes, or mist, that can be suspended in the atmosphere.

Photosynthesis

The process by which green plants use light to synthesise organic compounds from carbon dioxide and water. In the process oxygen and water are released. Increased levels of carbon dioxide can increase net photosynthesis in some plants. Plants create a very important reservoir for carbon dioxide.

Precautionary Approach

The approach promoted under the Framework Convention of Climate Change to help achieve stabilisation of greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous interference with the climate system. The ‘precautionary principle’ is often used to describe a strategy which is based on the argument that the potential price of not taking action can outweigh the cost of taken an action, even when scientific uncertainty exists about the need and likely outcome.
