Under a White Sky: The Nature of the Future

Under a White Sky: The Nature of the Future by Elizabeth Kolbert

Humans of gone to great effort to engineer nature to their designs. While this has often worked well in the short term, the long term is quite a different story. There are many cases of plants or animals that were introduced to help with a local issue, only to have caused even greater issues. People have also built many structures to combat one problem only to have another problem surface. The water control structures in Louisiana have helped prevent floods (when they work). Yet, the floods are what deposited sediment to keep the land.

After discussing the many unintended consequences of engineering the planet, the book pivots to climate change. We have spewed so much carbon into the atmosphere that we are impacting the climate. By some accounts, even if we stop all carbon emissions we are still on a bad path. That leaves reducing carbon in the air as a potential solution. How could that go wrong? The book first explores various carbon sequestering schemes in a positive light. Then puts on the cautious hat. Humanity does not have a good record looking at all the long-term consequences and impacts of the big projects. Alas, we are still continuing down the route. Will switching to electric cars really make a difference when the freeways themselves are impacting ecosystems? Could carbon captures just encourage more bad behavior? Or will it lead to a negative feedback loop in the other direction? Climate change does not have easy solutions.
