Time-lapses 🎥 taken from space can help track how Earth’s polar ❄️ regions are changing, watching as glaciers retreat and accelerate and ice sheets melt over decades. #AGU19 #AGUCryo

Thanks to @USGS/@NASA_Landsat’s 🛰 long data record, we can watch Alaskan glaciers ❄️ shift and flow every year since 1972. Columbia Glacier, which was relatively stable in the 1970s, has since retreated rapidly as the climate continues to warm 🌡.
@USGS @NASA_Landsat The Malaspina Glacier has pulsed and spread and pulsed. The flashes 💥 and imperfect frames result from the need for cloud-free images 📷 from each year, and the technology limitations of the early generation satellites.
