<\/p>\n<\/p>\n
Good morning from Japan, where my son and I have been traveling the past two weeks. We landed in Tokyo amid 102.4-degree heat (39.1\u00b0C), which almost made it kokushobi or a \u201ccruelly hot day\u201d\u2014a designation introduced in April to warn the public when temperatures rise above 40 degrees Celsius. There\u2019s also the torrential rainfall this summer, including last week\u2019s historic downpour in Chiba Prefecture that stranded travelers, disrupted power, and killed at least 8 people. But Japan is not just a nation having another frighteningly hot summer\u2014it has become one of the world\u2019s most advanced climate-adaptation labs, one U.S. leaders and companies may look to as temperatures climb here.<\/p>\n
It\u2019s a tough battle, even in a country that\u2019s long been used to dealing with earthquakes, eruptions, tsunamis, typhoons, heat waves and floods. Almost every Japanese household has access to air conditioning while only a fifth of European households do, which a new Swiss Re report warns has left much of the continent ill-equipped to handle the shock of current heat waves.<\/p>\n
One challenge for Japan is changing office culture, which has long expected men to dress in suits while women are expected to wear stockings and formal skirts. Despite a city government campaign to encourage workers to wear polo shirts and shorts to the office this year amid record-breaking heat and the Iran energy crisis, I saw plenty of men in jackets and ties.<\/p>\n
The government strengthened workplace heatstroke-prevention rules last year, requiring employers to have reporting, cooling and medical-response procedures in place. And employers are stepping up. Contractor Obayashi Corp. shifted construction work from 7 a.m. to 1 p.m. at heat-exposed sites this summer, instead of the usual 8 a.m. to 5 p.m. schedule. Seibu Railway has installed air-conditioned rest areas with refrigerators, and companies are issuing cooling garments, salt tablets, fans, and heat-monitoring devices. And Japan\u2019s growing use of robots in agriculture to supplement its shrinking population of farmers carries the added advantage of creating workers immune to heat.<\/p>\n
Of course, rescheduling work hours or sports tournaments, much like shifting crops or fishing practices amid warming oceans, doesn\u2019t address the fundamental issues contributing to more extreme weather or reduce the overall risks. Allianz estimates countries like France, Italy and Spain could face cumulative heat-related GDP losses of up to 7% by 2030.<\/p>\n
While the business case for dealing with climate change is obvious, the growing impact coincides with silence from the private sector, especially in the U.S. Maybe that\u2019s because of the rollback of climate-change policies in Washington, a backlash against ESG or sensitivity about the growing emissions toll of AI. Japan didn\u2019t feel it could afford to wait for the world to agree on climate change before adapting to it. The question for U.S. business leaders is, how much heat can they take before they start to do the same?<\/p>\n

There isn\u2019t just one AI bubble<\/p>\n
The question of whether AI is a bubble is the wrong one, Dhaval Joshi argues. The right question is: which AI bubble is popping today? Rather than your classic idea of one giant bubble building until it implodes, this is rather a rapid-fire sequence of bubbles popping and inflating in a rolling pattern. Investors are misjudging, and then correcting, who or what will actually capture AI\u2019s value.<\/p>\n
Trump\u2019s immigration plan may be backfiring<\/p>\n
In 2024, he pledged to bring back the American Dream. Removing immigrants \u201ctaking jobs from American workers and driving down their wages\u201d was a key part of the plan. But Mark Zandi, chief economist at Moody\u2019s, recently noted foreign-born unemployment fell below native-born unemployment in October 2025, based on analysis of a 12-month moving average of seasonally unadjusted data.<\/p>\n
Amodei sees crisis of trust<\/p>\n
Anthropic CEO Dario Amodei acknowledged the public has a negative view of AI, which he considers a big problem, but didn\u2019t place the blame on himself or any other individual AI executive. \u201cI think it is fundamentally a crisis of trust. I think that ordinary people don\u2019t trust companies, governments, or the tech industry and always suspect that we are cooking up some new way to screw them over.\u201d\u00a0<\/p>\n
The markets<\/p>\n

South Korea\u2019s KOSPI was shut for a national holiday. China\u2019s CSI 300 was up 1.61%. Hong Kong\u2019s Hang Seng was up 1.34%. India\u2019s NIFTY 50 was down 0.09%.
