'Zombie fires' in the Arctic: Canada's extreme wildfire season offers a glimpse of new risks in a warmer, drier future

Large stretches of the Arctic are carbon-rich peat bogs. As the region warms and dries, lightning strikes can spark underground fires that can burn for years.

The melting Arctic is a crime scene. The microbes I study have long warned us of this catastrophe – but they are also driving it

To fully understand the extent of climate-related dangers the Arctic – and our planet – is facing, we must focus on organisms too small to be seen with the naked eye.
