Once a generation an environmentalist dares to speak truth to power with such force that they cannot be silenced.

In Episode 4 of the How To Academy Podcast, Matthew Stadlen meets David Wallace-Wells, whose terrifying vision of unfolding climate catastrophe may just be the wake-up call we need to save the future.

Climate change is worse, much worse, than you think. The slowness of climate change is a fairy tale, perhaps as pernicious as the one that says it isn’t happening at all, and if your anxiety about it is dominated by fears of sea-level rise, you are barely scratching the surface of what terrors are possible, even within the lifetime of a teenager today.

In this podcast, David presents a sober, scientific but utterly terrifying vision of the unfolding 21st century. What will it be like to live on a pummelled planet? What will it do to our politics, our economy, our culture and sense of history? And what action can we all take, today, to minimise the damage?
