Stark differences in climate impacts between 1.5 and 2 degrees of warming
A difference of just half a degree of global warming, from 1.5 to 2 degrees Celsius, would mean that an additional 5 million people worldwide will have the land where their homes are located be permanently submerged underwater, according to a new study published in the journal Environmental Research Letters.
Historians to climate researchers: Let’s talk
Ours is not the first society to be confronted by massive environmental change. Over the course of history, some societies have been destroyed by natural disasters, like Pompeii, while others have learned how to accommodate floods, droughts, volcanic eruptions and other natural hazards. The key is how a society plans for and interacts with the stress from nature, say Princeton University historians John Haldon and Lee Mordechai.
So close, yet so far: Making climate impacts feel nearby may not inspire action
Jonathon Schuldt, assistant professor of communication at Cornell University, says it is possible to make faraway climate impacts feel closer. But that doesn’t automatically inspire the American public to express greater support for policies that address it. The paper appeared in the Journal of Environmental Psychology.
Arctic sea ice becoming a spring hazard for North Atlantic ships
More Arctic sea ice is entering the North Atlantic Ocean than before, making it increasingly dangerous for ships to navigate those waters in late spring, according to new research.
Glacier mass loss: Past the point of no return
Researchers from the Universities of Bremen and Innsbruck show in a recent study that the further melting of glaciers cannot be prevented in the current century — even if all emissions were stopped now. However, due to the slow reaction of glaciers to climate change, our behavior has a massive impact beyond the 21st century: In the long run, five hundred meters by car with a mid-range vehicle will cost one kilogram of glacier ice. The study has now been published in Nature Climate Change.
Thawing permafrost produces more methane than expected
In a seven-year laboratory study, Dr. Christian Knoblauch from Universität Hamburg’s Center for Earth System Research and Sustainability (CEN) and an international team have shown, for the first time, that significantly more methane is produced by thawing permafrost than previously thought. The findings, published in Nature Climate Change, make it possible to better predict how much greenhouse gas could be released by the thawing of the Arctic permafrost.

Why union members earn higher wages than their non-union colleagues
Craig McMillan et al
Over recent decades in Australia union membership has fallen from 40% of the workforce in 1990 to 15% in 2016 and so unions might seem less relevant in making a difference to what we earn. But our research finds that union members do earn higher wages per hour than non-union members.
