I was editing articles about global warming clear back in 1993!

I was cleaning out some stuff at home and found some old Sci/Tech sections, which were part of the Sunday Telegraph back when we were flush with news-hole and had room to do stuff like that. I edited the section, where my column (then called Science from the Sidelines) ran.

I was surprised to find an August 1993 section with a big story and art from National Geographic News Service talking about research into the effect of methane on global warming - with "global warming" in the 6-column headline, and the story barely explaining the concept, assuming that the reader already knows about it.

1993 - wow! That was 13 years before "Inconvenient Truth", which some people think invented the global-warming meme. I had forgotten that the idea was so entrenched that early.

Meanwhile, research into sources and global-warming effects of methane continue: A newly found source is decay during dam drawdowns.
