https://archive.is/ozASI Does anyone else find the Economist's lack of bylines and complete author anonymity to be off-putting? It's scary how much influence they have and how no one seems to mind that they don't feel comfortable putting their names on the stuff the advocate for and report on. Great article!

The first-line accountability is deliberately on the editors rather than the reporters.

this comments are like bingo for climate science misunderstanding evolution doesn't happen on time scales of 100 years +1.1 avg temperature implies much larger localized changes

> evolution doesn't happen on time scales of 100 years Evolution may not, but selection may happen on that time scale, especially for animals that live short lives.

What is the difference between selection and evolution?

Selection is a process by which evolution works, so this is a false distinction. Modern definitions of evolution are usually something along the lines of changes in a population over time. There's no inherent time scale over which those changes can be observed, except for that of the generation time itself.

First, journalists shouldn’t be “advocating” for anything. Second, a byline only serves the purposes of allowing ad hominem attacks rather than focusing on the content.

Animals bodies evolve to adapt to changes in the environment. This is nothing new. It's literally the process that has driven life forward since life first appeared. And given that the planet has so far only warmed an average of 1.1 degrees celcius due to climate change, isn't it a bit overzealous to blame animals' adaptation on climate change?

The worldwide average doesn't really tell the full story, because there can be significant local extremes that are far greater.

It burned to the ground due to a wildfire caused by sparks from a train, not from the heat. https://en.wikipedia.org/wiki/Lytton_wildfire

Wildfires don’t spread much better in 90F vs 121F. The big thing that causes uncontrollable spreads is lots of fast wind.

Unfortunately the title makes a small logical leap. From the article: "Her team combined data from different species in different places. Since they have little in common apart from living on a warming planet, she says, climate change is the most plausible explanation." While climate change may indeed be the most plausible explanation, this headline seems to transform from "most plausible" into a causal link.

One of big alternative explanations why animals/humans get smaller closer to tropics is not because of lack of food, but because of too much of it

The quicker the species can grow to maturity, the more food calories can be spent for procreation.

That's missing the point a bit. That said, vegetation sure does get dry fast in a 120 degree heat wave, though.

The way they do it is significantly better than almost any other magazine out there in my opinion.

Why do you think this is a relevant critique to the article/paper? The study is about a global trend in increasing appendage size within populations due to warming ("Allen's rule"), not whole body size ("Bergmann's rule"). Secondly, the role of food is acknowledged as a potential factor in the section on causality, but justifiably rejected as the sole factor.

Quite the opposite. I appreciate that the focus is on the content of the article and not the author.
