> The headline is wrong

In case you've been living under a rock, in the current cultural context "warmest ever" means "warmest since records began".

What year did records begin?

What did the data set look like then (spatial diversity, measurement variance, etc...)

How do you compare that data set to one collected this year?

Disable JS. I personally have a deciated browser for reading stuff with JS off by default and enable it for each site I consider it deserves JS (like if is using it for interactivity,maps or is a true app and not an article)

Okay, add the phrase “in recent time” which is the relevant assumption

The headline's meaning is obvious - it's clear what you are doing.

So then you know that I am calling out the headline of scientific article for being a lie. Do you think headlines of scientific articles should be lies?
