I wrote a term paper on global warming once. Granted, it was 15-20 years ago, but I found out that, if past trends repeat, right now the Earth is nearing the end of a 10,000 year warming cycle and is about to plunge into another ice age.
Also, at one point in the past the average temp on Earth was some 14 degrees warmer than now, while scientists are going berzerk 'cause the average temp raised one degree in the last hundred years.

Cylinders are the reason for the hydraulic circuit. They take the fluid power delivered from the pump and magically change it into mechanical power. There are many types of cylinders that one might run across on a farm scenario. Each one could take a chapter in
