English: This is a key to a world map showing surface temperature trends between 1950 and 2014. Temperature trends range from -0.5 to +0.5 degrees celsius per decade, and are shown by color gradients: Cooling trend: dark to light blue; No trend: white; Warming trend: light to dark orange
Global surface temperature (GST) is the average temperature of Earth's surface. More precisely, it is the weighted average of the temperatures over the ocean and land. The former is also called sea surface temperature and the latter is called surface air temperature. Temperature data comes mainly from weather stations and satellites.
Graph showing ocean temperature versus depth on the vertical axis. The graph shows several thermoclines (or thermal layers) based on seasons and latitude. The temperature at zero depth is the sea surface temperature. The ocean temperature plays a crucial role in the global climate system, ocean currents and for marine habitats.

An ocean current is a continuous, directed movement of seawater generated by a number of forces acting upon the water, including wind, the Coriolis effect, breaking waves, cabbeling, and temperature and salinity differences. [1]
A world map is a map of most or all of the surface of Earth. World maps, because of their scale, must deal with the problem of projection. Maps rendered in two dimensions by necessity distort the display of the three-dimensional surface of the Earth. While this is true of any map, these distortions reach extremes in a world map.
This template is used to display a clickable world map to help users navigate a large list of countries by continent. Include the following where you want the map to appear: {{world image map}} The image map assumes that in-page links to all the continents exist, e.g., #Africa, and in some cases, individual countries, e.g., #Canada.
