Climate change is not just threatening our planet, but also our minds. In my WhoWhatWhy podcast, I examine the hidden mental health crisis triggered by climate change with neuroscientist-turned-environmental-journalist Clayton Page Aldern.

Aldern takes us on an eye-opening journey through cutting-edge research, exposing the ways our changing environment is physically altering our brains and behavior. From cognitive impairment sparked by rising temperatures to the psychological aftermath of natural disasters, he paints a haunting portrait of a crisis that has been largely ignored.

A Rhodes scholar who holds advanced degrees in neuroscience and public policy from the University of Oxford, Aldern is a research affiliate at the Center for Studies in Demography and Ecology and the author of the new book The Weight of Nature: How a Changing Climate Changes Our Brains.
