The variability of climate extremes is important! We need to adapt to what there is and what is to come.
The amount of human impact / agency on climactic conditions beyond regional studies, are guesses based upon modeling simulations. Those simulations are extremely complex and routinely negate the findings of one another. I had to do this type of work in graduate school, it's surprising to say the least. Much more work is needed.
So I would be cautious in our opinions for or against human agency as a very high impact variable. There is no sense in taking an extreme position one way or the other. There is a need for as much research as possible.
What makes the most sense:
- Adapt to the environment we have and we think we will have in the next 5 years.
- Continue to do the science necessary to answer these questions the best we can without politics or prejudgement.
