Debate Opening Statement Can we change our impact on the rate of global warming? There are all these campaigns for us to combat global warming and reduce our emissions‚ we have all the science to maybe not stop it but effectively reduce it to stable conditions. It is evident that the temperatures and sea levels are rising and this proves global warming is out there; but it still doesn’t make a difference we still do nothing because Global warming is irreversible; we are so deep

Chapter 19 Nuclear Energy 19.1 Energy in your life Almost everything around us uses electricity and in order to power these devices‚ we must generate it. To create electrical energy‚ we must create thermal energy. Several techniques include using coal‚ natural gas‚ or nuclear thermal to create heat. Once heat is created‚ it is used to vaporize water and use the steam to propel a piston which turns an electric generator. Alternative energy sources include wind‚ solar‚ and micro hydro. 19.2 Nuclear
