Grasping time and glacier instability
Concept of time
In the real world we can move spatially forward or backwards, but time only moves in one direction: forward. A video of an event played backwards would seem unrealistic. This real world asymmetry of time is what is known as the “arrow of time”, the notion that time moves in only one direction. And surprisingly enough there is no simple explanation for this.
This talk will explore the different arrows of time, the possible explanations and the concept of time itself, which intertwines with our very concept of consciousness.

The Greenland and Antarctic ice sheets are two massive glaciers resting on the biggest island on Earth and on one whole continent. They store water equivalent to 65 meters of sea level rise. In the last two decades, they have contributed to 1.2 mm of sea level rise per year, in response to atmospheric and ocean warming. In this presentation, I will address these questions: Why and how are they melting? How much will they melt in this century and beyond? How stable are these glaciers? Which observational and modeling tools do we use to research on these ice sheets? How can we protect them?
