What can we expect from specialty coffee in 2025?
Once defined by its passion, specialty coffee has become more pragmatic – and emerging trends push it further in this direction.

There is no linearity assumption in how the warming rate is typically estimated
Also calling an entire scientific community idiotic is a rather bold statement not based on any actual evidence

Yes that looks about right

Absolutely you can! But the 5th percentile means we have a 5% chance of exceeding 2C in the next 15 years, not 90% as you led this string with.

My whole point was that a linear trend over only 10 years is (as you so nicely put it) linear nonsense. A linear trend through the 10 years from 2004 to 2014 gives almost no warming at all which was clearly an underestimate. Similarly the trend from 2014 to 2024 is an overestimate of the true rate

If you so the math on the Copernicus estimate (1.39C now and reaching 1.5C by Hune 2029), they are using 0.26C per decade

It’s not going to change dramatically — one additional year has limited power to shift the long-term trend
If Hansen’s estimate is just a 10-year trend drawn through the observations, I would not use this, in the same way that a 10-year trend through the hiatus period was wrong
