I produced this two part video podcast on the future of international assessments as part of my work for the Tyndall Centre. In the first part Tyndall Exec. Director Robert Nicholls in conversation with Prof. Bob Watson talks about the basic components of the science-policy interface that these assessments are trying to inform and influence; second, the key criteria needed to produce an influential assessment; and third, where are we today with assessments and where do we need to go from here to make needed progress? In the second part, they talk about the key things in climate assessment and related areas that are currently in progress, an assessment of where we are today — are we on track with biodiversity and climate goals? And lastly, we discuss what we need to do to address the environment and development challenges we face today in the 21st century.
