Understanding the Problem
For a medium-depth understanding of the science behind Climate Crisis and Peak Oil, take a look a recent paper by Celine McElvery of Hollis, NH: An Overview of Global Challenges: A look at Climate Change & Peak Oil and the Potential Implications for the Global Economy & Social Justice. A second paper Sustainable Solutions: A Path to a Brighter Future presents an overview of possible approaches to counter these challenges.
For a shorter version, please take a look at Harvard Local's page on understanding the key challenges we face.
A presentation given by Mark Archambault of Nashua, NH, for the StepItUp2007 November rally in Mason, NH, entitled Peak Oil, Climate Change and Sustainability: Meeting the mega-challenge of the 21st century provides a graphic overview of the problems we are facing.
