I would say:
The rope dissipates energy, yes. It does so by transforming the falling climber's kinetic energy into heat energy which is lost to the environment.
Work is done by the forces generated in the rope. Work transforms the kinetic energy of the falling climber into other forms of energy. Some of this transformed energy is stored in the rope as potential energy (like a spring). Some of the energy is transformed into heat by the friction between rope fibers as well as by the breaking of chemical bonds in the rope (this is why your rope gets stiff and wears out). Eventually the stored potential energy transforms into more heat energy (as you slowly bounce to a stop) and is dissipated into the environment. Ultimately, falling increases global warming and should be avoided.
Wrong
Although not entirely... it's still wrong
The energy transferred to heat and noise and such will not make a large enough difference to make your fall noticeably softer
as Jay already said F=ma
F is the force on your body
m is your mass
a is your bodies acceleration
acceleration is the change in velocity (m/s) over time (s) which gives you m/s^2 ... (metric)
your change in velocity is constant... you're going from falling to stopped with any type of rope.
a dynamic rope will increase the time required to stop your fall...
when you divide m/s by a larger s you get a smaller F
get it??????
