Study finds human influence in the Amazon's third 1-in-100 year drought since 2005 | John Abraham
Deforestation and climate change appear to be amplifying droughts in the Amazon
If you are like me, you picture the Amazon region as an ever lush, wet, tropical region filled with numerous plant and animal species. Who would imagine the Amazon experiencing drought? I mean sure, if we think of drought as “less water than usual,” then any place could have a drought. But what I tend to envision with respect to drought is truly dry.
People who work in this field have a more advanced understanding than I do about drought, how and why it occurs, its frequency and severity, and the impact on natural and human worlds. This recognition brings us to a very interesting paper recently published in Scientific Reports, entitled Unprecedented drought over tropical South America in 2016: significantly under-predicted by tropical SST [sea surface temperature]. So, what did this paper show?

Why do endangered right whales keep dying off the coast of Canada?
Researchers are racing for answers after at least 10 deaths of north Atlantic right whales, marking the deadliest year since tracking began
Researchers are scrambling to figure out why one of the world’s most endangered whale species is dying in “unprecedented” numbers, after at least 10 north Atlantic right whales have been found floating lifelessly off the coast of Canada.
The first whale carcass was reported in early June. Within a month, another six reports came in, leaving researchers reeling. This week, after several carcasses washed up on the shores of western Newfoundland, Canadian officials confirmed that the number of whale deaths had risen to at least 10, making 2017 the deadliest year for the marine mammal since researchers began tracking them in the 1980s.

Inscrutable all-seeing dragonfly overhead
Hamsterley Forest, Weardale Their visual sensitivity challenges us and their ability to track small fast objects is unparalleled
Much of Hamsterley forest lay in deep shadow and the scent of conifer resin hung in the still air between the spruces. No one had passed this way this morning; there were intact spiders’ webs stretched across the path high above Spurleswood beck.
And there we found a female golden-ringed dragonfly, Cordulegaster boltonii, clinging to rushes, still grounded by the lingering chill of the night. It’s the largest and, with its jet-black and yellow markings, the most startling, dragonfly species in the north Pennines.
