The story goes to note the cause of death is unknown – and then links the death to climate change, of course.
And this one: Disney Marathon Runner Passed Out From Heat Exhaustion Day Before Collapsing And Dying At Race
The first paragraph: “While authorities are still investigating what caused a Disney runner to die, it’s possible that heat played a factor in the young man’s death. Temperatures were in the triple digits on the day that he died. In fact, he even complained about the heat shortly before his death.”
Except those statements are not true. In fact, the run started at 5 AM when the temperature was in the low 70s. He had complained about running in the heat on days BEFORE the race.
The story says he went into cardiac arrest – which is not how heat exhaustion -> heat stroke normally work – particularly since it was only in the mid-70s at the time this occurred – a critical fact omitted from the news story.
The race began at 5 AM on September 8, 2024: Temperature was 71 degrees at race start. Most half marathon runners would be done within 2 hours, or by about 7 am – when the temperature was in the low to mid-70s, NOT TRIPLE DIGITS as reported by the media.

Temperatures only reached triple digits on September 6, two days before the race, and that was in the afternoon, long after morning events had finished.

It appears unlikely his death in mid-70s temperatures was caused by climate change. As in zero chance.
