The 2019-2020 fires in Australia are associated with a slow history of human activity.

> Three hours north, in Sydney, the air quality was worse than in Jakarta. [....]
> There is no doubt that the fires are growing more ferocious. Even without the changing climate, it would be inevitable; 250 years of land mismanagement have changed the way in which Australia’s bushland reacts to a spark.

> ... a fascinating study by Javier Miranda, principal economist at the U.S. Census Bureau; Benjamin Jones, professor at the Kellogg School of Management at Northwestern University; and Pierre Azoulay, professor at MIT’s Sloan School of Management and research associate at the National Bureau of Economic Research. They took a detailed look at the demographics of successful entrepreneurship. The results were so conclusive as to debunk the myth of the young startup founder. They paint a portrait that is much more consistent with your own intuition from experience.

> They conclude: “The mean age at founding for the 1-in-1,000 fastest growing new ventures is 45.0. The findings are similar when considering high-technology sectors, entrepreneurial hubs, and successful firm exits. Prior experience in the specific industry predicts much greater rates of entrepreneurial success.”

"Sleep fragmentation, microglial aging, and cognitive impairment in adults with and without Alzheimer’s dementia" | Science Advances | Dec. 2019 at advances.sciencemag.org/conten doi:10.1126/sciadv.aax7331

As a mature adult, is a bad cycle of sleeping poorly impacting your cognitive function?

> Dr. Lim, an associate professor of neurology at the University of Toronto ... suggest[s] microglia play a role in the link between poor sleep and cognitive impairment and dementia. Microglia normally help fight infections and clear debris from the brain. But dysfunction of microglia appears to be involved in the development of Alzheimer’s disease, Dr. Lim said. [....[

> Dr. Liu-Ambrose, the Canada research chair in physical activity, mobility and cognitive neuroscience at UBC, said good-quality sleep is believed to allow the brain to clear itself of toxic beta-amyloid protein, the buildup of which is one of the characteristics of Alzheimer’s disease. And, she said, there is also good evidence to suggest an accumulation of beta-amyloid can further contribute to disrupted sleep.

> “It’s a vicious cycle,” she said.

Declarations of sapiosexuality may describe individuals seeking partners for intellectual intercourse.

> A self-described “sapiosexual," someone who is primarily attracted to intelligence over physical appearance, Van Dusen says she now screens her dates for post-secondary education. [.....]

> Many sapiosexuals acknowledge the term can come off elitist, but in the often superficial world of online dating, they say, identifying as such helps them foreground their interests to potential partners. Sex researchers point out there is a difference between a sexual preference and a sexual orientation.

> There is almost no academic research on sapiosexuality, says Dr. Lucia O’Sullivan, a psychology professor and sexuality researcher at the University of New Brunswick. But, she says, there are plenty of studies that show most people value intelligence in romantic partners.

In the Canadian press, this is attributed to inverted yield curve, resulting from the trade war.

> Anyone buying that bond is willingly buying an investment that's guaranteed to lose money, but investors are more than happy to buy it up - because the fear is that alternative investments will fare even worse. [....]
> Those negative yields are filtering down into the economy in some truly jaw-dropping ways. A Danish bank this week started offering a negative yielding mortgage ...

There's something seriously wrong in the global financial markets, when banks are offering mortgages at zero or negative rates.

> Jyske Bank, Denmark's third largest, has begun offering borrowers a 10-year deal at -0.5%, while another Danish bank, Nordea, says it will begin offering 20-year fixed-rate deals at 0% and a 30-year mortgage at 0.5%.
> Under its negative mortgage, Jyske said borrowers will make a monthly repayment as usual – but the amount still outstanding will be reduced each month by more than the borrower has paid.

Extreme weather conditions could lead to disruption in regional food supplies, says an IPCC report published in August 2018.

> It is projected that for every degree of global warming, the world's yield of wheat will fall six per cent, corn by 7.4 per cent, and rice and soybeans both by a little more than three per cent each. Together those four crops account for two-thirds of the calories consumed by people, and with the population growing by 80 million people each year on average, the world needs to produce more food, not less.

"Canadian food supplies at risk if climate change not slowed: UN report" | Mia Rabson (The Canadian Press) | Aug. 8, 2019 at ctvnews.ca/sci-tech/canadian-f

> Cynthia Rosenzweig, a senior research scientist at the NASA Goddard Institute for Space Studies in New York City and one of the coordinating lead authors of the IPCC report, said much of the world relies on trade to access food, which increases global vulnerability if food production is affected across several regions at the same time.

While we should be satisfied with "making do", we should also appreciate that it's human nature to be (sometimes) frivolous.

> Making do is a deeply pragmatic philosophy. It means asking of our things the only question we should ever ask of them: “Can you fulfill your intended use for me?” [....] Taken literally, it simply means making something perform – making it do what it ought to do. [....]
> The challenge, of course, is that making do is at odds with human nature. As products of evolution, we are predisposed to seek novelty, variety and excess; now, we hunt for bargains, not mastodons. [....]
> In other words, to be frivolous is to be human. To aspire to pure pragmatism – to own only necessities – is misguided.

Agriculture responds to climate change, with chicken farmers switching to ducks, and shrimp fisherman switching to crabs.

> The advantages of ducks for farmers such as Akter [in Bangladesh] are several. Chickens catch infections much more easily than ducks do when they get wet, too hot, or too cold, Helal Uddin, the BRAC agriculturalist who first came up with the duck program, told me. [....]
> Nor is it just ducks. In the southwest of Bangladesh, crab fattening is on the rise. Its proponents hope crabs, which sell at high prices—especially the meatier ones—can form part of a new coastal economy, stemming the tide of migration to the cities.

Single Large or Several Small (SLOSS) sees a systems approach where individuals care for their property in a way that benefits all.

> ... while emphasizing connectivity may help threatened species be more resilient, Dr. Fahrig says that it should not be taken as a reason to disregard small pockets of nature that are not connected to anything. On the contrary, such places could be more important than their size and isolation suggest because they offer a final redoubt for some populations of plants and animals in a particular region.
> To some extent, this runs contrary to the emphasis on protecting large, undivided natural spaces. The debate is known by its acronym, SLOSS, for “single large or several small.” Dr. Fahrig maintains that while it’s always better to conserve more habitat than less, it needn’t be all in one place and there may be no lower threshold for what size of area matters.

Fit the people around an organization; or an organization around the people? Working backwards, say @MitroffCrisis + , from current concrete choices to uncertain futures, surfaces strategic assumptions in a collective decision, better than starting with an abstract scorecard to rank candidates.

Our house is on the edge of a flood plain. We know this, because the end of our street in Toronto Riverside was at Lake Ontario, before landfill in the early 1900s. Not everyone knows about what's under the place where they live.
