This challenge is critical to achieving Cardano's mission, since contributing to addressing climate change is tied to Cardano's mission as a world changer. Therefore, based on the given information, I strongly agree with this proposal's alignment, I can rate the alignment of this proposal with a score of 5.

In my opinion, Cardano's mission has as central to its goals, the transformation of the world in to a better place. Central to achieving this goal is taking on Climate Change. Using the issues around energy consumption, and Cardano's 'low energy profile' as a Proof of Stake blockchain, and building in projects that help align to the goals of professionalism, transparency, honesty and integrity, should be central to Cardano's mission, and I think they are. This will help to insure Climate issues are part of those goals. The Challenge Setting will also attract both a lot of creative builders, and voters into the ecosystem.

A Climate Change dedicated Challenge might indeed incentivize further development on impactful real world use cases in innovative ways. We have seen during past funds many Climate Change related proposals scattered through different challenges and in my view some very good ideas didn't obtain enough attention to develop and be fruitful. We can ascertain community willingness in putting forward creative proposals addressing human activity and climate. Furthermore, community interest in proposing Climate themed solutions will enable a diverse evolution of developer and open source app ecosystem with global impact. We have seen already in past funds an array of proposals related to waste management, circular economies, sustainable housing, animal conservation, farming and so on. Climate Change affects everyone and everything on the planet. In conclusion I shall pose the question : How is this challenge not critical to achieve Cardano's mission?

Cardano's ecosystem and blockchain technology lack meaningful connections to the real world. As a result of this challenge, we may be able to bridge the gap between decentralized finance and campaigns to combat climate change and bring tremendous value and good publicity to the cause. Having an understanding of how climate change impacts Cardano and its users would be helpful to guide proposers.

Proposers define success measures that are simple, quantitative, and auditable. In this way, the community will know how close or far a certain initiative is to success. In this regard, I agree that the success criteria and suggested metrics are appropriately defined to track progress in addressing the challenge.

Suggested metrics are logical and measurable to measure progress in addressing the challenge, except one that is quite unclear/hard to measure ["Is your proposal financially sustainable after funding?"]. Therefore, based on the given information, I still agree with this proposal's verifiability, I can rate the verifiability of this proposal with a score of 5

It is my humble opinion that the success criteria and suggested metrics are set to measure in addressing the challenge. I am in no way an expert in the field of Climate Change science, but, I feel the PSMs (Proposal Success Metrics) are, although a bit broad, sufficient in setting a frame or set of expectations for measurable KPIs. I might like to see, however, some hints or suggestions to quantify things like 'How big is the awareness that will be created'. But I guess it is more for the proposers who have problems to solve and submit to the Climate Change Challenge, to come up with those details, right?! (based on specifics in their projects!).

I believe Key Metrics could have been more developed and detailed such as: organizations engagement, local communities involvement, partnerships, population numbers, waste management volumes, carbon credits, geographical areas coverage, and so on. The Proposal Success metrics are listed in questions "how big.." . These are non quantifiable measures causing difficulty on auditability, however Challenge team could revisit those metrics further down the line, once proposal get voters approval.
