Warming debate shifts to �tipping point� Now that most scientists agree human activity is causing Earth to warm, the central debate has shifted to whether climate change is progressing so rapidly that, within decades, humans may be helpless to slow or reverse the trend.
BBC News: Rising concentrations of greenhouse gases may have more serious impacts than previously believed, a major scientific report has said.
The report, published by the UK government, says there is only a small chance of greenhouse gas emissions being kept below “dangerous” levels.
This brings up a good point on some alternative fuels to gasoline. Fortune published a piece recently arguing for the use of Ethanol. I don’t think this is our best choice. Crop production in the United States is already draining our Natural Resources faster than the enviroment can replenish them. The water supply from the Ogallala Aquifer for example is a concern for many farmers in the United States because it supplies so much (70% of all Kansas’s water) of the water used in the mid west. Groundwater depeletion and specfically depletion of the Ogallala is something we should take very seriously.
So I decided to look at the “alternative fuels” that the Department of Energy is considering to replace Oil. On their webpage they have a CGI script that will generate a table that compares the different fuel types, with a link to a PDF containing all the information you can use to do the comparison. Methanol sounds like the best from the choices they have.
