An environmental gradient, or climate gradient, is a change in abiotic (non-living) factors through space (or time). Environmental gradients can be related to factors such as altitude , depth, temperature , soil humidity and precipitation .
A gradsect or gradient-directed transect is a low-input, high-return sampling method where the aim is to maximise information about the distribution of biota in any area of study. Most living things are rarely distributed at random , their placement being largely determined by a hierarchy of environmental factors.
Indicator value is a term that is used in the ecology of plants for two different indices. The older usage of the term refers to Ellenberg's indicator values from 1974, which are based on a simple ordinal classification of plants according to the position of their realized ecological niche along an environmental gradient.

An automated prognostic chart of the 96-hour forecast of 850 mbar geopotential height and temperature from the Global Forecast System. Atmospheric models are computer programs that produce meteorological information, including prognostic charts, for future times at given locations and altitudes. [10]
The path or series of states through which a system passes from an initial equilibrium state to a final equilibrium state [1] and can be viewed graphically on a pressure-volume (P-V), pressure-temperature (P-T), and temperature-entropy (T-s) diagrams. [2] There are an infinite number of possible paths from an initial point to an end point in a ...
Climate drawdown refers to the future point in time when levels of greenhouse gas concentrations in the atmosphere stop climbing and start to steadily decline. [1] Drawdown is a milestone in reversing climate change and eventually reducing global average temperatures. [2]
In mid December, in France’s foreign ministry, Bouverot, faced an unusual dilemma. Across the table, a South Korean official explained his country’s eagerness to join the summit.
This composite of a conventional line chart superimposed on a warming stripe graphic illustrates year-by-year correlation of data points and coloured stripes. [ 21 ] "I wanted to communicate temperature changes in a way that was simple and intuitive, removing all the distractions of standard climate graphics so that the long-term trends and ...
