“By 2100, the ice sheet will shrink to the size it was during the last time the world was hotter than today.”
“The Greenland ice sheet is on track to lose mass at about four times the fastest rate observed over the past 12,000 years. At its current trajectory, such melting would dump huge quantities of freshwater into the sea, raising global sea levels and disrupting ocean currents, scientists concluded in new research Wednesday.
The new findings, published in the journal Nature, warn that the only way to avoid a drastically accelerated meltdown of the massive ice sheet in coming decades is for the global community to curtail emissions of greenhouse gases in the near-term.
Greenland is already the largest contributor to sea level rise, though Antarctica has the potential to increase sea levels even more. As sea levels creep upward, coastal storms including hurricanes and nor’easters become more destructive. Recent trends in more frequent “sunny day flooding” at high tide in places such as Annapolis, Md.; Norfolk; Charleston, S.C.; and Miami is also linked to sea level rise.”
“A company operating one of the world’s largest zinc mines in Northwest Alaska said thawing permafrost linked to global warming forced an expenditure of nearly $20 million on water storage and discharge management.
Teck Resources Ltd. says permafrost thaw in the watershed surrounding the massive Red Dog Mine is releasing higher natural levels of dissolved minerals and other particles into streams, Alaska’s Energy Desk reported Tuesday.”

“The intensifying rivalry over sea routes and mineral resources in the Arctic, itself a consequence of the climate emergency, has caused alarm over its environmental impact.
“Even during a pandemic and nationwide protests against state violence, the Trump administration is still finding new ways to exploit the climate crisis. He is truly the worst president for the planet we’ve ever had,” Charlie Cray, a senior researcher for Greenpeace USA, said.
“There are so many ways our tax dollars could be used to support Arctic communities. Helping out the oil industry and the military with a new fleet of icebreakers is definitely last on the list.”
Polar military experts are also sceptical over the urgency of the “icebreaker gap” with Russia.
“Icebreakers – even if armed – don’t really address some of the most commonly cited challenges that China and Russia might pose for the United States in the Arctic,” Paul Avey, assistant professor for political science at Virginia Tech university, argued. “This isn’t to say icebreakers can play no role in competition. But in narrow defence terms, I think that the best way to address China and Russia in the Arctic – and Antarctic – is to focus on issues in eastern Europe and the western Pacific.”

In those early months, I, along with most of the rest of the country, was using “surge capacity” to operate, as Ann Masten, PhD, a psychologist and professor of child development at the University of Minnesota, calls it. Surge capacity is a collection of adaptive systems — mental and physical — that humans draw on for short-term survival in acutely stressful situations, such as natural disasters. But natural disasters occur over a short period, even if recovery is long. Pandemics are different — the disaster itself stretches out indefinitely.
“The pandemic has demonstrated both what we can do with surge capacity and the limits of surge capacity,” says Masten. When it’s depleted, it has to be renewed. But what happens when you struggle to renew it because the emergency phase has now become chronic?
By my May 26 psychiatrist appointment, I wasn’t doing so hot. I couldn’t get any work done. I’d grown sick of Zoom meetups. It was exhausting and impossible to think with the kids around all day. I felt trapped in a home that felt as much a prison as a haven. I tried to conjure the motivation to check email, outline a story, or review interview notes, but I couldn’t focus. I couldn’t make myself do anything — work, housework, exercise, play with the kids — for that whole week.
Or the next.

I know depression, but this wasn’t quite that. It was, as I’d soon describe in an emotional post in a social media group of professional colleagues, an “anxiety-tainted depression mixed with ennui that I can’t kick,” along with a complete inability to concentrate. I spoke with my therapist, tweaked medication dosages, went outside daily for fresh air and sunlight, tried to force myself to do some physical activity, and even gave myself permission to mope for a few weeks. We were in a pandemic, after all, and I had already accepted in March that life would not be “normal” for at least a year or two. But I still couldn’t work, couldn’t focus, hadn’t adjusted. Shouldn’t I be used to this by now?
“Why do you think you should be used to this by now? We’re all beginners at this,” Masten told me. “This is a once in a lifetime experience. It’s expecting a lot to think we’d be managing this really well.”
It wasn’t until my social media post elicited similar responses from dozens of high-achieving, competent, impressive women I professionally admire that I realized I wasn’t in the minority. My experience was a universal and deeply human one.”
