@getjonwithit Fascinating, from your summary it sounds similar to neuro-symbolic architecture. Thank you

New paper! What if you could guarantee (using a mix of formal verification and PDE theory) that a neural network would *always* give you the correct answer, even when making inferences arbitrarily far away from the training data? Introducing BEACONS. arXiv link below. (1/15)

@KHayhoe Fantastic achievement. Now let’s operationalise that. Make it the decision support tool for industry and government.

@ajw42 That is a good summary of the last 20 years of my research career. I was one of the very first to evaluate regional impacts under both a higher and lower scenario explicitly to motivate policy to avoid the risks of the higher scenario. And we did! library.ca.gov/wp-content/upl…

If I were polling people on the likelihood of blowing past the Paris targets, I wouldn't ask climate scientists: I'd poll CEOs, elected officials, and leaders, at every scale. I'd ask WHY they felt that way. And I'd want those answers shared. For more: linkedin.com/feed/update/ur…

The western Canadian province of Alberta on Tuesday declared an early start to wildfire season as a result of an unusually dry and mild winter, allowing the government to put more money and resources into tackling blazes. reut.rs/3I7bzRv reut.rs/3I7bzRv

@KHayhoe I understand, we are hosting a panel discussion and I was going to ask if you wanted to participate.

@ajw42 No, I am not attending this COP.

@KHayhoe Just wondering if you will be at COP in December?

@ajw42 I apologize, I didn’t recognize your name & didn’t read your bio before responding!

@KHayhoe No worries, thank you again. I have some ideas on how to operationalise climate modeling for decision support systems that could build upon the STAR-ESDM methodology. It would be great to have your input

@KHayhoe Thank you, I am up to speed in the field and actively build upon it. As a start up we are siloed at the moment but contribute to academia through publications and open source where we can. Thanks again for the link

@ajw42 So, the article is the traditional peer reviewed submission, written for specialists so it doesn’t give much background. If you want to understand the field, I highly recommend cambridge.org/core/books/dow…

@KHayhoe @ClimateOfGavin Thanks for the article! May I ask you some questions about it once I have read through it?

@ClimateOfGavin totally agree, but there's a step missing - bias correction and downscaling. many take it for granted but it's not that easy! essopenarchive.org/doi/full/10.22…

@ClimateOfGavin Yes to all the above and that something we are Riskthinking.ai are currently working on.

@PhysInHistory @shanwhiz this is for you

Within Vancouver, there is a place called Gastown. Why does it have that name, and what is the story behind its famous steam clock? Let's dive into the history of Gastown, Vancouver's oldest neighbourhood! Long before there was a Gastown, the local Indigenous Peoples used the area as a portage route between Burrard Inlet and False Creek. At high tide, they could paddle between the two bodies of water. They called the area Lekleki, meaning "grove of beautiful trees". Gastown was named for "Gassy" Jack Deighton, a Yorkshire seaman and barkeep who came to the area in 1867. He ran the Globe Saloon in New Westminster and realized that his customers walked five hours in some cases to get a drink as they could not drink on mill property. After leaving an American in charge of his saloon while he was out of town, he came back to find it was bankrupted by a July 4 celebration. So, he loaded a canoe with a barrel of whiskey, two hens, his dog and supplies. With $6 in his pcoket, he and his family went to Burrard Inlet. According to legend, in exchange for building him a saloon, he offered mill workers whiskey. That first saloon was a 12x24 foot shack but it was up and running within 24 hours. He was well-known for talking at length, which was called "gassing". As a result, the area around his saloon became known as Gassy's Town. That later became, Gastown. When the Hastings Mill sawmill and seaport were built, Gastown quickly grew to become the centre of trade for the area. It also developed a reputation for being a rough and tough place as off-work loggers and fishermen came in to blow off some steam. Of the 10 buildings in Gastown in 1875, four were saloons. On March 1, 1870, to give the area a more respectable name, Gastown became Granville. Everyone who lived in the area still called it Gastown though. With some rough characters in the area, that also meant a jail was needed. The first jail was built around the 1880s, and was a two-cell building made of logs. For decades, Gastown was referred to as skid-row. This phrase may have come from the practice of sending greased logs down the streets to the mill for processing. In the 1960s, the Gastown area was scheduled for demolition to build a freeway. A campaign was led by the business community, property owners and political protesters to save the area. It was around this time that the name Gastown came back into popular use. The revitalization and gentrification of Gastown began in large part thanks to Henk F. Vanderhorst, a Dutch immigrant who opened the Exposition Gallery on Water Street. The most famous aspect of Gastown is the steam-powered clock. This was built in 1977 to cover a steam grate as a way to harness the steam and prevent people from sleeping on the spot in cold weather. Today, it is a major tourist attraction. Its cobblestone streets are also quite new, built following efforts to save the area from demolition. In 2009, Gastown became a National Historic Site of Canada.

@ScottDuncanWX @McgowanHamish and this is winter!

Record-breaking winter heat in the Southern Hemisphere. Perth airport in Western Australia 🇦🇺 just recorded its hottest winter day on record (records go back 79 years here). Cape Town Observatory, South Africa 🇿🇦 records its hottest August day on record with 32.9°C. Records here go back 63 years here.

@CraigBaird You publish a book on this it would be wonderful anthology.

After several weeks, I've reached the end of my Indigenous Peoples history posts. I covered every nation I could. If I missed any, let me know. Hope everyone enjoyed it!

@CraigBaird This is the best account on twitter, thanks Craig!

This is a great example of how to view shifting climate risk. Thanks @RARohde
