It's not useless - it's just limited.

"Warmest decade in 160 years" still tells you something. It just doesn't tell you _everything_. As we can never have perfect data on everything, learning to take things in context and understand what they are good for (and what they aren't) is a vital skill.

I would have thought though that 160 years when studying climate, is absolutely nothing.
