Climate Hope City: how Minecraft can tell the story of climate change

On the rooftops, there are endless luscious gardens, so that the skyline of the city looks almost like the tree tops of a vast rain forest. Beneath them, lining the roads, are multi-storey farms, producing fruit and vegetables for the local populace. There are strange sail-shaped constructions that suck CO2 out of the air, and along the canals, hydrogen powered boats glide silently through crystal clear waters. This is Climate Hope City – and for now, it exists only in Minecraft.
