The imminent dangers of climate change have attracted considerable attention from the scientific community in recent years. Researchers from a wide variety of backgrounds have begun to examine the causes and potential effects of climate change from biological, economic, and other perspectives. The climate change debate has also evolved considerably in recent years. While disagreements about the existence of climate change were much more common several decades ago, today most recognized contemporary scientists agree on its existence (“Fifth Technical Summary of the Assessment Report,” 2014). . Furthermore, the idea that climate change is non-existent is widely seen as an outright denial of reality, while current dialogue in the scientific world dwells on the severity of its consequences. The scientific community has also reached consensus that current human activity is unsustainable, although the time frames for the most disastrous and irreversible effects vary. On the contrary, the shift to the sustainability debate has raised many more questions, not to mention many different definitions of sustainability. . Naturalists today debate the establishment of "ecological limits," while social scientists debate the feasibility of making necessary adjustments to human behavior through existing social institutions. One such debate takes place in the context of transportation, where participants focus on the question of how to meet humanity's mobility needs while reducing greenhouse gases and other emissions. There are many different viewpoints in this discussion, from broader perspectives on the need for transportation as a whole, to more focused perspectives on potential combinations of transportation... middle of article. ."
