35 years of climate change in one video

By Johnny Wood 18 November 2019 (WEF) – Q: If you subtract 95 percent from something, what’s left? A: An environmental crisis. The “something” in question is the oldest and thickest solid layer of frozen water in the Arctic Ocean, which is melting so rapidly that just 5% of its original mass remains. Scientists from the […]

(a) Estimated distances animals can travel during the Phocine distemper virus (PDV) latent and infectious period (1 week, 2 weeks, and 4 weeks) illustrating the areas where viral transmission could occur, based on median travel speeds calculated for satellite-tagged bearded seals (green circles), spotted seals (orange), Steller sea lions (blue), and northern fur seals (purple). (b) Recorded tracks of a PDV seropositive bearded seal followed in July 2009 and a seropositive northern fur seal followed in November 2010 shown with sympatric PCR positive spotted seals, ribbon seals, and northern fur seals sampled 2009–2010. Sea ice is shown at its minimum extent in September (panel a) and retreating the following July after reaching a maximum winter extent (panel b).

Deadly virus spreads among marine mammals as Arctic sea ice melts – Scientists fear the virus, once found only in European waters, could spread to the U.S. West Coast

By Sarah Gibbens 7 November 2019 (National Geographic) – When sea otters in Alaska were diagnosed with phocine distemper virus (PDV) in 2004, scientists were confused. The pathogen in the Morbillivirus genus that contains viruses like measles had then only been found in Europe and on the eastern coast of North America. “We didn’t understand how a […]
