Roundup: Snowmaking Guns, Antarctic Ice, and Black Carbon

Ski Resort’s New Snowmaking Guns 

Describing a major ski resort in British Columbia, Canada: “De Jong says that after commercial operations end in July, four snowmaking guns and other infrastructure will be installed. It is expected to be used beginning in October. ‘If the pilot project is conclusive, this unique project will become a significant addition to Whistler Blackcomb’s list of adaptations to ensure long-term resilience against climate change,’ he said.”

Sudden and Rapid Ice Loss Discovered in Antarctica

“Several massive glaciers in the southern Antarctic Peninsula suddenly started to crumble in 2009, a new study reports today (May 21) in the journal Science. ‘Out of the blue, it’s become the second most important contributor to sea level rise in Antarctica,’ said lead study author Bert Wouters, a remote sensing expert and Marie Curie Fellow at the University of Bristol in the United Kingdom.”

“We analyzed refractory black carbon (rBC) in an ice core spanning 1875–2000 AD from Mt. Muztagh Ata, the Eastern Pamirs [of western China], using a Single Particle Soot Photometer (SP2)…. Mean rBC concentrations increased four-fold since the mid-1970s and reached maximum values at end of the 1980s. The observed decrease of the rBC concentrations during the 1990s was likely driven by the economic recession of former USSR countries in Central Asia. Levoglucosan concentrations showed a similar temporal trend to rBC concentrations, exhibiting a large increase around 1980 AD followed by a decrease in the 1990s that was likely due to a decrease in energy-related biomass combustion. The time evolution of levoglucosan/rBC ratios indicated stronger emissions from open fires during the 1940s–1950s, while the increase in rBC during the 1980s–1990s was caused from an increase in energy-related combustion of biomass and fossil fuels.”
