Accumulation of a very potent greenhouse gas has stopped.

4. It didn't come from me. I never heard of this molecule, unless I forgot about doing so.

I am an old man, and sometimes I forget things.

I'd imagine that it would be a useful methylating reagent, maybe less toxic than dimethylsulfate and cheaper than methyl iodide or bromide.

Methylating agents, all of them, are fairly toxic because they methylate tyrosines and thus screw with any and all kinase substrates, but it's always useful to have methylating agents, and it seems that this molecule might fit somewhere in a "tunable" set of such agents.
