Amazon rainforest sees biggest spike in deforestation in more than a decade – “Forests fall, indigenous leaders are killed, and environmental laws are shattered”

By Colin Dwyer 18 November 2019 (NPR) – Picture, for a second, just how vast New York City is. All told, including Staten Island, the Bronx and every block in between, the massive metropolis takes up more than 300 square miles. Now, try to picture a hunk of land more than 12 times that size. That’s […]

(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 […]

More than 11,000 scientists issue warning of climate emergency – “An immense increase of scale in endeavors to conserve our biosphere is needed to avoid untold suffering due to the climate crisis”

5 November 2019 (BioScience) – Scientists have a moral obligation to clearly warn humanity of any catastrophic threat and to “tell it like it is.” On the basis of this obligation and the graphical indicators presented below, we declare, with more than 11,000 scientist signatories from around the world, clearly and unequivocally that planet Earth […]

Greater Sydney dam levels on 17 November 2019. Dams in greater Sydney are currently at 46.6 percent capacity. According to the NSW water authority, they are on track to hit 40 percent, which means Level 2 water restrictions would be imposed by February 2020 or March 2020. Since June 2019, the greater Sydney area in New South Wales state has been under Level 1 water restrictions, which limit water usage in filling pools or running hoses unattended. It is the first time the restrictions have been implemented since 2003, during a drought that lasted until 2009. If dam levels drop just a few percentage points in greater Sydney, residents could face even harsher water restrictions. Graphic: WaterNSW

Dangerous air pollution in India forces Delhi schools to close for 2nd time in 2 weeks – “I cannot play outside because the air is too toxic to breathe”

DELHI, 15 November 2019 (CBS News) – The air pollution in India’s capital got so bad again this week that the government was forced to close schools. It was the second time in two weeks. The air has been choked with a concentration of noxious pollutants about 10-times higher than what’s considered safe by the […]

Arctic shifts to a carbon source due to winter soil emissions – “The warmer it gets, the more carbon will be released into the atmosphere from the permafrost region, which will add to further warming”

By Samson Reiny 8 November 2019 (NASA) – A NASA-funded study suggests winter carbon emissions in the Arctic may be adding more carbon into the atmosphere each year than is taken up by Arctic vegetation, marking a stark reversal for a region that has captured and stored carbon for tens of thousands of years. The […]

Just 15 years of post-Paris emissions to lock in 20 cm of sea level rise in the year 2300 – “Emissions today will inevitably cause seas to rise a long way into the future. This process cannot be reversed. It is our legacy for humankind.”

5 November 2019 (PIK) – Unless governments significantly scale up their emission reduction efforts, the 15 years’ worth of emissions released under their current Paris Agreement pledges alone would cause 20 cm of sea-level rise over the longer term, according to new research published today in the Proceedings of the National Academy of Sciences (PNAS).
