Science is based on fact, general opinion is not. This survey doesn't say anything about global warming, if anything it shows why democracy is pretty rubbish at dealing with reality or getting anything done.
I very much doubt whether carbon taxes are any use at combatting this but if anything they are a desperate attempt to hold back our increasing demands for power as we are about to go into a period of brownouts and astronomical electricity prices thanks to political heel dragging in commisioning new power plants.
Do you know what the safest, cheapest, most environmentally friendly source of power is? Nuclear. More scientific fact overruled by general populace idiocy and paranoia.
