Tough to tell exactly what you’re referencing, but you might be thinking about the Paleocene–Eocene thermal maximum, which was a natural increase in carbon in the atmosphere that led to higher temperatures. So, in some ways very similar to what we’re seeing now, but if my understanding is correct, even the PETM which was “dramatic” on a geological timescale took thousands of years to ramp up, and played out over 200,000 years. What we’re seeing now is happening much quicker, and is highly correlated with human influence.
Counter example to what? Why should they not be able to run both a relatively open ecosystem and a mostly closed one?
I don’t think Apple is arguing that it is impossible to allow more open ways to install apps on iPhones. I think they’re saying that they don’t want to, and that they shouldn’t have to.
Likely because they are tall and tilted in a direction facing the sun, so that the moisture blocks more of the light than it would if the sun was hitting it at a more oblique angle.
