Study findings suggest that switching from coal to natural gas would do little for global climate

Green Car Congress

The study will appear next month in the peer-reviewed journal Climatic Change Letters. It would be many decades before it would slow down global warming at all, and even then it would just be making a difference around the edges. —Tom Wigley. However, the effects of natural gas on climate change have been difficult to calculate.
