It is way past time to look a all implications of climate change. Production and use of fossil fuels are just one part of a very complicated global system. As a retired earth scientist I am increasingly concerned that despite some hopeful forecasts we are way past the tipping point - we cannot stop this. Governments world wide need to look at what needs to be done to prepare for the worst in terms of extreme weather, wide spread drought, and disruption of the ocean ecosystems. A complete ban on expansion of development on ocean front areas would be one place to start.
