We couldn't fit all of Mark Howden's insights into our Local Environment Heroes conversation, so we're sharing his full Impact Hour talk as bonus content.

In this June Impact Hour session, Emeritus Professor Mark Howden AC takes a clear-eyed look at where we are heading on climate change — and where there are still genuine reasons for hope.

Drawing on almost 40 years working across climate science, policy, and sustainability, Mark explores current emissions trajectories and what they mean for Australia and the ACT. He also looks at the practical opportunities available to avoid the worst impacts of climate change, from renewable energy and electric vehicles to adaptation and emissions reduction.

Mark discusses climate reality, without losing sight of climate hope or the paths for change that remain within reach.

Recorded at Dissent Cafe & Bar, Canberra, in June 2026.
