The year 2016 saw the largest number of refugees since World War Two and the worst bleaching ever recorded in the Great Barrier Reef. The dissolution of coral reefs globally may be an apt metaphor for the foundations of civil society and their fragility: slow erosion punctuated by sudden, catastrophic failure.

Bushfire threatens a structure in Tasmania, 21 January 2016. The fires destroyed vegetation that is unique to Tasmania, including iconic alpine species, such as the Pencil Pine and cushion plants, as well as temperate rainforests. The fires burned up large areas of organic soils, on which the unique Tasmanian vegetation depends. It is extremely unlikely burnt areas with the endemic alpine flora will ever fully recover.

Homecoming begins for residents of fire-ravaged Canadian city – ‘It is not a clean, safe, normal environment that you’re walking into’, Unusual heat wave fuels fire at Fort McMurray Photographer Sebastian Copeland was trekking in the Canadian Arctic when he came across this distressing sight of a polar bear's emaciated corpse on a patch of rocky ground. The animal starved to death as a result of climate change which have caused the ice to retreat, making it impossible to hunt seals. Photo: Sebastian Copeland

Sebastian Copeland was trekking in the Canadian Arctic when he came across a polar bear’s emaciated corpse surrounded in molted fur on a patch of rocky ground. Mr. Copeland believes it serves as a graphic illustration of the plight facing polar bears as the sea ice retreats, making it harder to hunt seals and forcing them further inland for food.

In speaking with the locals in Kaktovic, they've noted that it's been an unseasonably warm winter, and that the ice will be late in forming this year. This will have an impact on the local polar bear population, when it comes time to hunt seals for their food in the winter months. Photo: Patty Waymire / National Geographic Your Shot

22 April 2016 (mongabay.com) – The quest for gold has been stripping rainforest from around rivers in the Amazon Basin, with not even protected areas immune from mining. The situation has gotten so out of hand that the Peruvian government launched an intervention in January, destroying a slew of mining equipment and more than a thousand gallons of fuel in the southern part of the country in effort to stamp out production. But recent satellite and aerial data show this hasn’t had the intended effect, with a big recent uptick in mining-related deforestation along the Upper Malinowski River inside Tambopata National Reserve.
