The biggest issue with climate change is the uncertainty associated with it. Our lack of knowledge adds on to the challenge. Whatever actions we take, we will make mistakes. It's important to learn from the mistakes and evolve. We cannot be disappointed by failure.
There is a concept called Adaptive management in environmental studies. In adaptive management, hypothesis driven experiments are designed. The results of these experiments are closely monitored. Any deviation in results from what was expected at the time of planning is considered as new learning and incorporated into the next level of experiments. Uncertainty is considered to be an opportunity to learn complex ecosystem functionality.
Climate change may be the best place to implement adaptive management due to the complex nature of climate change and its uncertainties.
