This is what the Siberians call a "drunken forest". Permafrost that has not melted provides a solid foundation that holds trees upright. When permafrost melts, as it has here, the layer of loose soil deepens and trees lose their foundations, tipping over at odd angles.
As fall gets going and winter looms, snow is sure to come. And sure as the snow will fall there will be those who confuse or conflate the freezing temperature of water with record cold and proclaim global warming solved. Here's the reality:
Several feet underneath much of Alaska is a layer of soil known as the permafrost, which as the name implies, is permanently frozen throughout the year — or at least it used to be. Over the last fifty years, Alaska has warmed twice as fast as the lower 48 and ground temperatures have been steadily increasing since the 1970s. Some models predict that by mid-century one-third of Alaska’s permafrost will have thawed and that by 2100, two-thirds will be gone.

While homeowners in parts of Alaska groan over cracked driveways and sinking decks, and the state grimaces at the expense of insulating its roads from the thawing ground, many tribal villages are sinking into the messy business of attempting to relocate.

  • We now know rogue planets exist, and because of the chaotic way solar systems are thought to form, they could well outnumber stars in our galaxy. The regular planets in our own solar system get weirder everyday.
  • Comet ISON has a 50/50 chance of surviving, and a past comet may have lit Egypt on fire millions of years ago.
  • Alzheimer's is one of the most brutal, dreaded fates we face collectively and individually. But we are learning about the molecular physiology of the disease, and this new drug is among those that could render the condition treatable in the next few years:
    In tests on mice, the Medical Research Council showed all death from prion disease could be prevented. "This finding, I suspect, will be the turning point in the search for medicines to control and prevent Alzheimer's disease."
  • It's taken almost a year of working out and dieting, but check out the emerging six-pack on my 51 year-old bod. It might look OK, but I just barely escaped a cancer diagnosis this week and I'm not completely out of the woods. Per usual, now I'm being threatened with losing my employer group health insurance. Our healthcare system is insane, inexcusable, and anyone who runs against improving it is immoral at best.

More Tagging tips:

A tag is a way to search for this diary. If someone is searching for "Barack Obama," is this a diary they'd be trying to find?

Use a person's full name, without any title. Senator Obama may become President Obama, and Michelle Obama might run for office.

If your diary covers an election or elected official, use election tags, which are generally the state abbreviation followed by the office. CA-01 is the first district House seat. CA-Sen covers both senate races. NY-GOV covers the New York governor's race.

Tags do not compound: that is, "education reform" is a completely different tag from "education". A tag like "reform" alone is probably not meaningful.

Consider if one or more of these tags fits your diary: Civil Rights, Community, Congress, Culture, Economy, Education, Elections, Energy, Environment, Health Care, International, Labor, Law, Media, Meta, National Security, Science, Transportation, or White House. If your diary is specific to a state, consider adding the state (California, Texas, etc). Keep in mind, though, that there are many wonderful and important diaries that don't fit in any of these tags. Don't worry if yours doesn't.
