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.

More reactions to the UK ambassador's departure

Unlike the Woody Donald Trump thrust into the Court of St James's, the UK's ambassador to the US, Sir Kim Darroch, has been a model of Britain's diplomatic civil service. Even his leaked cables (ask: who benefited from the leaks?) show a certain level of restraint that, as a professional diplomat, he didn't need to show.

Contrast that with the behavior of our diplomats overseas, let alone the guy who appointed them:

In Berlin, one U.S. ambassador openly undermines the government; another in Amsterdam became a laughingstock for refusing to answer journalists’ questions, and yet another in Jerusalem openly shows bias in Israeli-Palestinian negotiations. From Kenya to New Zealand, the ambassadors appointed by Trump have offended their hosts.

Ultimately, the rot comes from the top.

It took mere hours for Richard Grenell, the U.S. ambassador to Germany, to offend his hosts in May with a tweet that appeared to give an order: “German companies doing business in Iran should wind down operations immediately.” A month later, Grenell gave an interview with the conservative news site Breitbart in which he said he wanted to “empower” hard-right conservatives in Europe.

Meanwhile, David M. Friedman, the U.S. ambassador to Israel and Trump’s former lawyer, often appears much too cozy with his host government — and only interested in talking to one set of people in the Israeli and Palestinian territories. ... Along with Trump’s decision to move the U.S. Embassy to Jerusalem, the closure of its consulate in East Jerusalem and much more, it was yet another sign that the United States had picked a side.

The UK knows a thing or two about squandering good will in the world. And they still haven't completely recovered, despite (or perhaps because of) how much Russian money has flowed into London. So here we are, bankrupting ourselves diplomatically nearly everywhere we go. It's not so far from where we are today to two vast and trunkless legs of stone standing in the desert.

Sadiq Khan on Trump

I mentioned earlier that President Trump had insulted the Mayor of London. Here's what Khan wrote to make Trump so angry:

Praising the “very fine people on both sides” when torch-wielding white supremacists and antisemites marched through the streets clashing with anti-racist campaigners. Threatening to veto a ban on the use of rape as a weapon of war. Setting an immigration policy that forcefully separates young children from their parents at the border. The deliberate use of xenophobia, racism and “otherness” as an electoral tactic. Introducing a travel ban to a number of predominately Muslim countries. Lying deliberately and repeatedly to the public.

No, these are not the actions of European dictators of the 1930s and 40s. Nor the military juntas of the 1970s and 80s. I’m not talking about Vladimir Putin or Kim Jong-un. These are the actions of the leader of our closest ally, the president of the United States of America.

I am proud of our historic special relationship, which I’m certain will survive long after President Trump leaves office. The US is a country I love and have visited on many occasions. I still greatly admire the culture, the people and the principles articulated by the founding fathers. But America is like a best friend, and with a best friend you have a responsibility to be direct and honest when you believe they are making a mistake.

History teaches us of the danger of being afraid to speak truth to power and the risk of failing to defend our values from the rise of the far right. At this challenging time in global politics, it’s more important than ever that we remember that lesson.

Spot on.

Where plaid comes from

A farmer in Scotland tweaks American tourists:

A cheeky farmer is winding up American tourists by spray-painting her sheep tartan – and claiming it’s caused by the animals drinking popular Scottish soft drink, Irn-Bru.

Owner Maxine Scott, 62, used her skills with a spray-can to brighten up ewes April and Daisy.

Scott puts up a sign pretending that the sheep turn bright orange naturally and that their fleeces are then used to make tartan wool for kilts and blankets.

The sheep live on Auchingarrich Wildlife Centre, Comrie, Perthshire, and are decorated using marker spray, used by farmers to identify sheep during lamb numbering.

I wonder what clan they're in?

The UK's reputation in Europe

Whether you prefer "shooting oneself in the foot" or "circular firing squad" as your metaphor, the UK's flailing with just a week left to go before crashing out of the EU has disappointed many people in Europe:

For politicians, diplomats and officials across the continent, the past two-and-a-half years of the Britain’s fraught, seemingly interminable and increasingly shambolic departure from the EU have proved an eye-opener.

Some have responded with humour. Nathalie Loiseau, France’s Europe minister, said recently that if she had one, she would call her cat Brexit: “It wakes me up miaowing because it wants to go out. When I open the door, its sits there, undecided. Then it looks daggers at me when I put it out.”

Others have found it harder to laugh. To the shock of many, ;Brexit has revealed a country they long looked up to locked in a narrative of its own exceptionalism, talking mainly to itself, incoherent, entitled, incapable of compromise (with itself or its neighbours), startlingly ignorant of the workings of an organisation it has belonged to for nearly 50 years, and unrealistic.

Only, Britain has been here so many times before. Crashing out of India so hard that the country hasn't had a day of peace in 70 years? Check. Getting rolled by the Soviets after putting a Soviet spy in charge of rooting out Soviet spies? Check. Appeasing a fascist regime bent on European hegemony? Check.

And now, it seems, Russia has rolled them again, as no country stands to gain more from Brexit than they. And still they're flailing about, going through the worst Constitutional crisis (self-inflicted!) since the 17th Century.

It's really sad.

Once is accident, twice is conspiracy...

The House of Commons voted 391-242 this evening to reject PM Theresa May's slightly-revised Brexit deal, further throwing the country's prospects after March 29th into chaos:

Because of this defeat, tomorrow Commons will vote on whether to leave the EU without a deal, and if that vote fails, there will be a vote Thursday on whether to extend Article 50. If that vote fails...holy mother forking shirtballs, the UK is forked.

Chicago's sinking, but don't worry

Wherever a landmass had several kilometers of ice on top, it deformed. Glaciers covered much of North America only 10,000 years ago. Since they retreated (incidentally forming the Great Lakes and creating just about all the topography in Northern Illinois), the Earth's crust has popped back like a waterbed.

Not quickly, however.

But in the last century, Chicago has dropped about 10 cm while areas of Canada have popped up about the same amount:

In the northern United States and Canada, areas that once were depressed under the tremendous weight of a massive ice sheet are springing back up while others are sinking. The Chicago area and parts of southern Lake Michigan, where glaciers disappeared 10,000 years ago, are sinking about 10 to 20 cm each century.

One or 2 millimeters a year might not seem like a lot, but “over a decade that’s a centimeter. Over 50 years, now, you’re talking several inches,” said Daniel Roman, chief geodesist with the National Oceanic and Atmospheric Administration. “It’s a slow process, but it’s a persistent one.”

While Chicago’s dipping is gradual, this dynamic could eventually redefine flood plains and work against household sewer pipes that slope downward to the sewer main.

The same phenomenon has affected the UK as well. Scotland is popping up and England is sinking, as are other pairs of regions similarly glaciated. (Sterling, however, has a long way to go...)

London sets record for warmest day in winter

The UK Met has kept temperature records since 1910, and in all that time, London has never experienced a warmer day in winter than yesterday:

Temperatures in Kew Gardens, south-west London, reached 21.2°C, breaking the record for the warmest February day. The Met Office defines winter from the beginning of December to the end of February, so Tuesday’s sunny spell is also a winter record.

The record had already been broken on Monday, when temperatures exceeded 20°C during winter for the very first time. This week’s unseasonably warm weather differs dramatically from the beginning of the month, when sub-zero temperatures were recorded across the country.

The previous winter record had been 19.7°C in Greenwich, south-east London, in 1998.

“The average temperature for this time of year is 9°C in London and 9°C in north Wales, so what we’re seeing is Δ9°C degrees above average,” said Martin Bowles, a Met Office meteorologist.

Bowles said: “We can’t blame climate change directly because we’re talking about weather, not the climate. But it is a sign of climate change. There’s been a gradual increase of temperatures over the last 30 years so the extreme weather has also been increasing.”

Parts of Britain on Tuesday were hotter than Malibu, Athens, Crete and Barcelona.

The warmest day I ever experienced in London was in August, 2009, when the temperature hit 31°C. Yesterday was almost that warm, and August is still six months out.

Can't wait to see what the summer is like.

My next side-trip from London

...will be to Bletchley Park:

The National Museum of Computing is a must-see if you are ever in the UK. It was a short 30ish minute train ride up from London. We spent the whole afternoon there.

There is a rebuild of the Colossus, the the world's first electronic computer. It had a single purpose: to help decipher the Lorenz-encrypted (Tunny) messages between Hitler and his generals during World War II. The Colossus Gallery housing the rebuild of Colossus tells that remarkable story.

We saw the Turing-Welchman Bombe machine, an electro-mechanical device used to break Enigma-enciphered messages about enemy military operations during the Second World War. They offer guided tours (recommended as the volunteers have encyclopedic knowledge) and we were able to encrypt a message with the German Enigma (there's a 90 second video I made, here) and decrypt it with the Bombe, which is effectively 12 Engimas working in parallel, backwards.

I wanted to understand the computing power these systems had then, and now. Check out the website where you can learn about the OctaPi - a Raspberry Pi array of eight Pis working together to brute-force Engima. You can make your own here!

Yes, there's a Raspberry Pi Enigma-cracker. If only we'd had one in 1940...
