The only guarantee of the pa`s institutional effectiveness (e.g. B by removing barriers to transparency) may not be sufficient to achieve its objectives. Here we identify an intermediate channel that influences national and non-governmental action or environmental efficiency. The PA is consistently presented as a significant normative change, in which (all) nations agree on the urgent nature of the climate problem and recognize the need for collective action that goes beyond the pure state. In addition, it institutionalizes new elements such as loss, damage and human rights, broadens the way the climate problem is addressed and opens new doors to measures to combat climate change such as human rights conflicts or the need for orderly migration procedures that go beyond the Refugee Convention. The PA thus sends a signal to both private and public actors, helping to spread new ideas, set a common direction and maintain the momentum and support the fight against climate change. To support this approach, the PA establishes a number of processes that enable experimentation and learning, contribute to the dissemination of good practices and find innovative solutions to the climate problem. While this process of feedback and learning remains flawed and underdeveloped, one of the PA`s main successes is to create a platform for the exchange of experiences and ideas. As such, it increases the importance of climate change worldwide, helps reverse the global attitude towards the fight against climate change, and helps disseminate solutions thus facilitating the rapid transformations needed to achieve the PA`s goals.
Thus, the AP can develop over time in order to offer a future platform for the creation of the ambition still missing but necessary. In 2006, Spash was appointed Chief Executive Officers` Science Leader at CSIRO, the Australian Authority responsible for scientific research of the Australian Federal Government. Following the completion of a critical document on the Emissions Trading Scheme, which had already been peer-reviewed, the Agency intervened and insisted on substantial changes.  CSIRO`s behavior has given rise to controversial debates within the scientific community and Nature has reported in detail on the conflict.   As a result of the controversy, Spash left the Agency at the end of 2009.  In 2009, a new policy framework, the Copenhagen Accord, was signed. Although the parties recognized the need to limit global warming to < 2°C in order to avoid dangerous climate change, they did not agree on a clear path to a legally binding treaty to succeed the Kyoto Protocol, whose first commitment period would end in 2012. A consensus would not be reached until 2015, when a new partially legally binding treaty – the Paris Climate Agreement – will finally be signed that will oblige all parties to limit global warming to "well below 2°C". .
