Thank you so much. I once again want to thank our witnesses for coming today.
I know it has been a long couple of hours, especially for you, Mr. DeMarco, and I just have a final question to wrap up.
I want to thank you for coming and speaking to this very important report about lessons learned. I think it's very clear that all of us, all countries in the world, and all of us individually as people and citizens of the world, and all industries and sectors are going to have to do their part if we're going to be successful in mitigating the damage of climate change. We have a lot of catching up to do and we need to get on with it.
So I am wondering, Mr. DeMarco, if you could indicate which of these eight lessons are going to be easier to implement and which of them will be the most challenging. Thank you.
