Lunchtime must-reads

Just a few today:

That's all for this afternoon. Check back tomorrow to see if Israel has a government, if Saudi Arabia decides to take its $67 bn defense budget out for a spin, or if President Trump succeeds in putting homeless people in concentration camps.

A few good reads today:

Haven't decided what to eat for lunch yet...

It's hot and wet

Two articles on current consequences of climate change. First, the Post has a long-form description of how global temperature rise is lumpy, causing localized hot spots such as the one off the coast of Uruguay:

The mysterious blob covers 130,000 square miles of ocean, an area nearly twice as big as this small country. And it has been heating up extremely rapidly — by over 2 degrees Celsius — or 2C — over the past century, double the global average. At its center, it's grown even hotter, warming by as much as 3 degrees Celsius, according to one analysis.

The entire global ocean is warming, but some parts are changing much faster than others — and the hot spot off Uruguay is one of the fastest. It was first identified by scientists in 2012, but it is still poorly understood and has received virtually no public attention.

The South Atlantic blob is part of a global trend: Around the planet, enormous ocean currents are traveling to new locations. As these currents relocate, waters are growing warmer. Scientists have found similar hot spots along the western stretches of four other oceans — the North Atlantic, the North Pacific, the South Pacific, and the Indian.

Barring some dramatic event like a major volcanic eruption — which can cause temporary global cooling by spewing ash that blocks the sun — scientists expect this to continue and steadily worsen.

Climate change has also driven a policy shift in Canada:

Unlike the United States, which will repeatedly help pay for people to rebuild in place, Canada has responded to the escalating costs of climate change by limiting aid after disasters, and even telling people to leave their homes. It is an experiment that has exposed a complex mix of relief, anger and loss as entire neighborhoods are removed, house by house.

The real-world consequences of that philosophy are playing out in Gatineau, a city across the river from Ottawa that has been hit by two 100-year-floods since 2017. Residents here are waiting for officials to tell them if the damage from the latest flood, in April, exceeded 50 percent of the value of those homes. Those who get that notice will be offered some money and told to leave.

Canada doesn't have the constitutional protections for private property that we have in the US. But the approach works; they spend a lot less on clearances than on rebuilding, especially since they only need to clear once.

Not a slow news day

Let's see, where to begin?

Finally, RawStory has a collection of responses to the President's Sharpie-altered weather map. (This is not, however, the first time the Administration has tried to make one of its Dear Leader's errors be true.) Enjoy.

Funny things

First, something legitimately funny, especially if you're Jewish:

And some things that are funny, as in, "the President is a little funny, isn't he?"

OK, that's too much funny for this morning.

Happy autumn

Summer ends in about two hours here in Chicago, after a kind of perfect late-summer day. The day is ending with a cool, gentle rain, which will clear up before dawn.

The end of August being the end of summer infused art and music for millennia before meteorologists set September 1st as the first day of autumn for statistical convenience. Maybe this is happy alignment of science and art?

Here's Dar Williams with the verdict:

Afternoon articles

Just a few for my commute home:

  • New York Times reporter James Stewart interviewed Jeffrey Epstein on background a year ago, and it was weird.
  • The Post analyzes temperature records to find which parts of the US have warmed faster than others.
  • Chemist Caitlin Cornell may have discovered an important clue about the origin of life on Earth.
  • The site of the city's first Treasure Island store, just two blocks from where I lived in Lakeview from 1994-1996, might become an ugly apartment tower unless residents can block it.
  • Seva Safris digs into the differences (for good and ill) between JSON and XML.
  • Timothy Kreider delivers a stinging rant against gun-rights advocates: "The dead in El Paso and Dayton, whether they were shopping for back-to-school backpacks or just out having beers and hoping to get laid on a Saturday night, gave their lives so that you might continue to enjoy those freedoms."

I will now return to my crash-course in matrix maths.

Lunchtime reading

Yep, one of these posts.

Back to coding...

Requiem for a glacier

Researchers from Rice University and residents of Iceland have put up a memorial to a glacier that disappeared in 2014:

The memorial is “a letter to the future.” It describes what we lost: the Okjokull glacier — and how we lost it: human-caused climate change. And yet it is hopeful, acknowledging “what is happening and what needs to be done.”

“Only you,” future visitor, “know if we did it.”

It’s a reminder of geologic times gone by, like a Mount Rushmore but for the natural landmarks we’ve lost. The plaque, dedicated to Iceland’s first glacier lost to climate change, will be installed next month in Borgarfjordur.

[A]ll of Iceland’s glaciers are projected to melt in the next two centuries. The Rice University researchers say they hope this small memorial helps create a path forward for thinking about climate change and its impact.

It was an ice thing to do as well.

Yes, the climate has changed before...just not like this

As our planet warms to global average temperatures not seen in over 125,000 years, a pair of long-range studies has concluded the unique way or climate is changing right now, as opposed to the rest of history:

“The familiar maxim that the climate is always changing is certainly true,” Scott St. George, a physical geographer at the University of Minnesota in Minneapolis, said in a written commentary about the studies. “But even when we push our perspective to the earliest days of the Roman Empire, we cannot discern any event that is remotely equivalent — either in degree or extent — to the warming over the last few decades.”

One of the studies, published in the journal Nature, shows that the Little Ice Age and other natural fluctuations affected only limited regions of the planet at a time, making modern warming the first and only planetwide warm period in the past two millennia. The other study, published in Nature Geoscience, shows that the rate of modern warming has far outpaced changes that occurred before the rise of the industrial era.

For the Nature Geoscience study, the researchers charted global temperature averages over time, and then compared the data to a set of climate simulations to figure out what might have driven the changes. Neukom and his colleagues found that the fastest warming in the last two millennia occurred during the second half of the 20th century.

The researchers also found that the main cause of temperature fluctuations changed over time. Prior to 1850, fluctuations were mainly linked to volcanic eruptions, which cooled the planet by spewing sun-blocking ash into the stratosphere; after 1850, greenhouse gas emissions took the wheel.

As if to underscore that, today London saw temperatures over 37°C while France and other parts of Europe set new all-time heat records, with a reading of 42.6°C in Paris today.
