Record highs in Alaska this week.

One data point and all but all-time ever recorded temperatures all over the state.

Has anyone here actually read or even seen a copy of the study? Or is that unnecessary?

The link provided goes to a description of the study that is about 100 words long. Other than making a statement, it really tells us very little.

To read the whole thing requires a $20 subscription.

It may well be that the study shows something completely different. As happened in the published reports of warming in Western Antarctica earlier this year.

So, anyone actually seen the study? Anyone know what it actually says?

It says Puerto Rico is doomed and so is every on it both real and fictional.

So I gather that you have not seen the report and are just commenting out your ass.

Just like JfH, most Americans aren't that concerned about global warming. But those outside the U.S. are worried.

The Chinese should be worried about that gigantic dam of theirs. If it's built like other Chinese crap, it should be busting open any day now.

You mean the latest by Rignot et al.? I saw it. I even read it. Seeing it and reading it is probably necessary to understand it, although it's not particularly difficult. I think the brief summary, while accurate enough, misses the big picture, which is not really that ice loss is greater than in the past 1,000 years but that the system, although probably at equilibrium right now (ice gain vs. ice loss), is much closer to the tipping point than previously thought. This is because much more of the melting (and, therefore, the thinning of the ice cap) appears to occur from the underside of the floating ice shelves than originally thought, perhaps more than 50% of it. The rate at which that melting occurs is determined by the temperature and currents of the water underneath the ice shelves, which are classified as "cold ice cavities" or "warm ice cavities." The warm ice cavities are experiencing a net loss of their ice, whereas the cold ones are still slightly increasing their thickness, resulting in a rough equilibrium across the entire cap. However,
Continued warming of the ocean will slowly increase ice shelf thinning, but if major shifts in sea ice cover and ocean circulation tip even large ice shelf cavities from cold to warm (35), there could be major changes in ice shelf and thus ice sheet mass balance.

In other words, rather than a slow thinning, we might see sudden fast melting from the underside of the large ice shelves. Rignot et al. don't spell out the consequences in this piece, but the potential results of the destabilizing of the large ice shelves are well known, and range from slowly disastrous to suddenly catastrophic.

Goodbye, Miami is an interesting piece from Jeff Goodell at the Rolling Stone.

"Miami, as we know it today, is doomed," says Harold Wanless, the chairman of the department of geological sciences at the University of Miami. "It's not a question of if. It's a question of when."

Gov. Rick Scott, a Tea Party Republican, says he's "not convinced" that global warming is caused by human beings. Since taking office in 2011, Scott has targeted environmental protections of every sort and slashed the budget of the South Florida Water Management District, the agency in charge of managing water supply in the region, as well as restoration of the Everglades. "There is no serious thinking, no serious planning, about any of this going on at the state level," says Chuck Watson, a disaster-­impact analyst with longtime experience in Florida. "The view is, 'Well, if it gets real bad, the federal government will bail us out.' It is beyond denial; it is flat-out delusional."

From the article, which is well worth reading:

[climate specialist] Watson recalls attending a meeting on natural-hazard-response planning in South Florida, funded by the Federal Emergency Management Agency and the state: "I mentioned sea-level rise, and I was treated to a 15-minute lecture on Genesis by one of the commissioners. He said, 'God destroyed the Earth with water the first time, and he promised he wouldn't do it again. So all of you who are pushing fears about sea-level rise, go back and read the Bible.'"


I never saw it put quite so bluntly, but there's at least half your problem. The other half of course is the carbon-based fuel industries.

It's too bad the commissioner doesn't understand that God didn't promise not to destroy parts of the Earth with water and "Miami" is not "the Earth."
