Position Paper 1: Global Climate Change – Is climate change a natural phenomenon or caused by man? There has been some discussion and debate over the causes of global climate change and particularly‚ the causative forces that have contributed to the measured increase in the mean atmospheric temperature over the last several decades. Many researchers and climatologists have concluded‚ using climate modeling systems that the main cause is anthropogenic (man caused). Other researchers have

telecommunication systems. The familiar light bulb gives off light through incandescence‚ a phenomenon in which the heating of a wire filament by an electric current causes the wire to emit photons‚ the basic energy packets of light. LEDs operate by electroluminescence‚ a phenomenon in which the emission of photons is caused by electronic excitation of a material. The material used most often in LEDs is gallium arsenide‚ though there are many variations on this basic compound‚ such as aluminum gallium

Incompatibilism v. Compatibilism There are two prevailing incompatibilist views concerning free will‚ hard Determinism or Libertarianism. The former asserts that if determinism is true‚ then free will is nonexistent and humans are essentially robots following a path determined for us from our past and natural laws. The latter denies that determinism is true and thus appears to introduce randomness as an explanation to account for free will. Compatibilists claim that free will and determinism can
