Images of Melt: Earth's Vanishing Ice Midnight Iceberg The midnight sun glows off an iceberg in Disko Bay, Greenland. Icebergs calving into the sea are a major source of Greenland's ice loss. Meltwater Stream A stream of meltwater flows across the ice surface in Greenland. Doomsday Clock Set At 100 Seconds To Midnight, Issuing Dire Warning Of Apocalypse Topline: The Doomsday Clock was set 100 seconds to midnight Thursday⁠—20 seconds closer than its previous time⁠—indicating that the world is closer to the apocalypse than it has been since the Bulletin of Atomic Scientists began tracking it over 70 years ago. During a Thursday press conference at the National Press Club in Washington, D.C., former California governor Jerry Brown, Mary Robinson, the former president of Ireland, and former UN secretary general Ban Ki-moon unveiled the clock’s new time.Rachel Bronson, the group’s president and CEO, said, “Today we feel no more optimistic” about the world’s outlook, and that the current environment is unstable due to inaction on climate change and a precarious nuclear landscape, and urged the world’s leaders to act on these two issues, or else disaster will occur.“If decision makers fail to act, citizens around the world should echo the words of climate activist Greta Thunberg and say, ‘How dare you?’”

‘The devastation of human life is in view’: what a burning world tells us about climate change I have never been an environmentalist. I don’t even think of myself as a nature person. I’ve lived my whole life in cities, enjoying gadgets built by industrial supply chains I hardly think twice about. The Uninhabitable Earth: David Wallace-Wells on the horrors of climate change “It is, I promise, worse than you think.” That was was the first line of David Wallace-Wells’s horrifying 2017 essay in New York magazine about climate change. It was an attempt to paint a very real picture of our not-too-distant future, a future filled with famines, political chaos, economic collapse, fierce resource competition, and a sun that “cooks us.”

People who think their opinions are superior to others are most prone to overestimating their relevant knowledge and ignoring chances to learn more By guest blogger Tom Stafford We all know someone who is convinced their opinion is better than everyone else’s on a topic – perhaps, even, that it is the only correct opinion to have. Maybe, on some topics, you are that person. What's in your water? Researchers identify new toxic byproducts of disinfecting drinking water Mixing drinking water with chlorine, the United States' most common method of disinfecting drinking water, creates previously unidentified toxic byproducts, says Carsten Prasse from Johns Hopkins University and his collaborators from the University of California, Berkeley and Switzerland. The researchers' findings were published this past week in the journal Environmental Science & Technology. "There's no doubt that chlorine is beneficial; chlorination has saved millions of lives worldwide from diseases such as typhoid and cholera since its arrival in the early 20th century," says Prasse, an assistant professor of Environmental Health and Engineering at The Johns Hopkins University and the paper's lead author. "But that process of killing potentially fatal bacteria and viruses comes with unintended consequences. The discovery of these previously unknown, highly toxic byproducts, raises the question how much chlorination is really necessary."

The Greek Island That Became an Open-Air Prison for Refugees Samos, Greece When Leila, an elegant Afghan woman of 34, goes to bed, she squashes up beside her husband on the narrow bottom mattress of a bunk, while her teenage daughter and 11-year-old son share the bed above. Eighteen inches away, another family is crushed together on another bunk, and down the row stretch 20 more.

Non-survivable humid heatwaves for over 500 million people – Climate Guide Researchers at MIT warn that if climate change remains unchecked (Business As Usual-scenario = RCP 8.5) over half a billion people will, from 2070 onwards, experience humid heat waves that will kill even healthy people in the shade within 6 hours. The Wet Bulb Temperature (WBT) would exceed 35°C (95°F), at which the body – of any mammal – cannot cool itself, overheats and shuts down. Three regions were studied: China (2018), South Asia (2017) and the Persian Gulf (2015). The researchers predict (at RCP 8.5) WBT exceeding 35°C about once every decade for the Northern Plains in China (400+ million people), at locations in the Chota Nagpur plateau, northeastern India, and Bangladesh in South Asia (70+ million people).
