THERMAL EXPANSION



Most materials are subject to thermal expansion: a tendency to expand when heated, and to contract when cooled. For this reason, bridges are built with metal expansion joints, so that they can expand and contract without causing faults in the overall structure of the bridge. Other machines and structures likewise have built-in protection against the hazards of thermal expansion. But thermal expansion can also be advantageous, making possible the workings of thermometers and thermostats.

So if climate chnage isn't just another cycle, how did they grow wheat in greenland 1000 years ago? Destroy our economy on the basis of ignoring the second opinion of scientists who claim it is just another climate trend or cycle, not chnage? Why is it such expert scientists are considered nutters and the doomsayer, left wing scientists right becuase it sells a lot more papers and sounds right?
