The graph shows the amount and spread of ice on the surface of the ocean, called global “sea ice area” by scientists, dipping far lower than the established trends would have predicted.

The ice concentration graphs do show an overall rapid increase in ice. A few of the Great Lakes are now at normal ice coverage or even above normal ice coverage.

On a graph, the gradient is defined as being the change in the 'y' value divided by the change in the 'x' value. It defines how steep a line is. of the line is equal to the rate of reaction.
