A trove of material from the first SFI Global Sustainability Summer School is available for free to the public online. The scientists highlighted the following conclusions on climate and energy: Scientific evidence that our release of greenhouse gases risks dangerously warming the climate is incontrovertible. The technologies needed to start solving the problem exist today and many are ready for large-scale implementation, though a full solution will require a major commitment to further research and innovation. These low-carbon technologies represent a large economic opportunity, but the ordinary course of innovation and technological diffusion is too slow to meet the challenge of addressing climate change. Large-scale government intervention is therefore needed to accelerate this process.
