Climate change is now an inevitable result of human activities. The effects of planetary warning are already beginning to be experienced across the globe. Changes and intensifications in weather patterns and rising sea levels are causing wildfires, flooding, and other disasters. Future effects are likely to include crop failure or displacement, mass migration, and catastrophic damage to ecosystems. One of the most significant questions facing humanity is: what should be done? What are going to be the most effective ways to respond to this planetary-scale and complex challenge? Is it possible to mitigate against some of the worst effects of climate change? Or, should we instead focus on ways of adapting ourselves to the inevitable changes that are now sweeping across the earth? Should we expect technology to save us from climate change? What other approaches to the problem are possible? And, perhaps most importantly, how are we going to be able to mobilize the required resources to take any steps at all?
How should we best respond to the problem of a warming planet?
