By Jennifer Chu 20 September 2017 (MIT News) – In the past 540 million years, the Earth has endured five mass extinction events, each involving processes that upended the normal cycling of carbon through the atmosphere and oceans. These globally fatal perturbations in carbon each unfolded over thousands to millions of years, and are coincident […]
By Ben Panko 7 September 2017 (Smithsonian) – What if the world’s parasites suddenly went extinct? Given how much work we’ve put into combating malaria-carrying mosquitoes and horrifying Guinea worms, it sounds like a reason for celebration. But think twice: Actually, losing these much-despised mooches, bloodsuckers and freeloaders could have disastrous consequences for the environment […]
By Peter Brannen 11 July 2017 (The Atlantic) – “Who you with?” “I’m a science journalist,” I said, jolted from my reverie on the shoulder of I-68 in Maryland, where a crowd of geologists had gathered on a field trip to poke at some rocks revealed by the highway department’s dynamite. The rocks, slate gray […]
By Malia Wollan 18 July 2017 (The New York Times) — It was a freakishly warm evening last October when a maintenance worker first discovered the water — torrents of it, rushing into the entrance tunnel of the Svalbard Global Seed Vault, a storage facility dug some 400 feet into the side of a mountain […]

12 May 2017 (University of Exeter) – Dramatic drops in oceanic oxygen, which cause mass extinctions of sea life, come to a natural end – but it takes about a million years. The depletion of oxygen in the oceans is known as “anoxia”, and scientists from the University of Exeter have been studying how periods […]
By Clive Hamilton4 May 2017 (The Guardian) – After 200,000 years of modern humans on a 4.5 billion-year-old Earth, we have arrived at new point in history: the Anthropocene. The change has come upon us with disorienting speed. It is the kind of shift that typically takes two or three or four generations to sink […]
WEST LAFAYETTE, Indiana, 3 March 2017 (Purdue University) – New research findings show that as the world warmed millions of years ago, conditions in the tropics may have made it so hot some organisms couldn’t survive. Longstanding theories dating to the 1980s suggest that as the rest of the earth warms, the tropical temperatures would […]
By Alex Dale15 February 2017 (BirdLife International) – A new study suggests that half of all threatened terrestrial mammals, and a quarter of threatened birds, are already being negatively impacted by climate change. Could it prove the tipping point? Scepticism of climate change may be on the rise in some political circles, but there’s no […]
10 February 2017 (Stockholm Resilience Centre) – A paper recently published in the journal The Anthropocene Review puts the current rate of change of Earth’s life support system in the context of the last 4-billion-year evolution of the biosphere. The paper, which is written by the centre’s Owen Gaffney and senior research fellow Will Steffen, […]
