Text reads: 'It's spooky season here in Europe, and that means that ghost stories and folklore make their way into the light, but what happens if you are a professional 'hauntologist'?! Simon Clark spoke with Elizabeth Case, a researcher who studies the 'ghosts' of glacial landscapes. "Itโ€™s not all metaphorical: glaciers haunt from far away in time and space. Most people wonโ€™t go to Antarctica or Greenland; their interaction with ice is through sea level." Elizabeth comments. "Glaciers bring the past into the present by responding to climate over multiple timescales: long-melted glaciers haunt us, as terraformers that shaped the land." Read the full interview here. We also learned about how climate models are uncovering the shadows of past eruptions in a blog by Asmae Ourkiya on a recently published study on the Samalas volcanic eruption of 1257 in Indonesia, and the massive impact it had on global climate.
