A dynamic way of looking at global temperature is to plot it in phase space, which is usually with the position on the x axis and velocity on the y axis. Below is the phase space graph of global temperature since 1996 with temperature on the x axis and change in temperature on the y axis.
The graph of position versus velocity displays an inward spiral. In classical mechanics, this is described as an “attractor” and shows that the system is trapped in a potential well from which it cannot escape, as in this animation of a damped harmonic oscillator.
Graphs of temperature versus time show that the temperature since 1996 should be seen as a sinusoidal wave that decreases exponentially since the sudden impulse from the “El Nino of the Century” in 1997-8.
The phase diagram provides another way of showing that the global temperature has stopped warming. With average temperature acting as an “attractor”, the system has been trapped in a potential well for 15 years, that’s as good a description of “stopped” as you find in dynamics.
