The issue of climate change is suddenly a hot topic again.
The reason? The government needs money.
The rare northeastern Superstorm Sandy and a Democratic victory in the presidential election put global warming back into the picture.
Now a carbon tax is being discussed as one possible revenue answers in this looming budget crisis. People would pay a tax whenever they use fossil fuels, such as coal, natural gas or oil.
These are fuels that produce heat-trapping carbon dioxide.
The Conservative American Enterprise Institute held an all-day discussion about the carbon tax Tuesday.
Meanwhile, former Republican Congressman Bob Inglis said such a thing may be inevitable.
Wednesday, former vice president Al Gore launched a 24-hour online talkfest about global warming and natural disasters.
