While it's nice to think that everyone should bear responsibility for this crisis, only governments have the power to effect meaningful change, and therefore bear the most responsibility. Yes, people can change lightbulbs, add insulation and make other meaningful changes, and businesses can try to be as green as possible, but the reality is that we live in a capitalist world and that means that combatting climate change must make economic sense, and the biggest single source of CO2 is coal used for electricity production. Only government can do anything to rapidly (i.e., over 20-30 years) change this. Changing energy sources of energy isn't extremely difficult. We've done it before, when it was done either for convenience or economy. Most of you are probably aware that most homes were heated using coal before WWII, and earlier in our history wood was used. Now almost no one uses coal or wood at home. That conversion away from coal was done because of government stimulation of the electric and oil business. (The conversion from wood to coal took over 100 years - we can't take that long to change now.) Think the Rural Electrification Administration, the TVA, and oil subsidies. Government stimulated, and the result was a cleaner, more pleasant way to heat homes and a very robust economy. The task is no different now, and the results would be even better, except the vested interests are fighting to keep their coal and oil profits.
