January 10, 1991 – “Separate studies rank 1990 as world’s warmest year”  #ShiftingBaseline

Thirty two years ago, on this day, January 10, 1991, the New York Times ran a story that has become very very familiar.

The earth was warmer in 1990 than in any other year since people began measuring the planet’s surface temperature, separate groups of climatologists in the United States and Britain said yesterday.

A third group, in the United States, reported record temperatures from one to six miles above the earth’s surface. These were recorded from balloons from December 1989 through November 1990.

Stevens, W. (1991)  Separate Studies Rank ’90 As World’s Warmest Year  New York Times,  Jan. 10.

The amount of carbon dioxide in the air was roughly 355ppm. As of 2023 it is 419. .

The context was that the US had finally been forced to agree to take part in negotiations for a world climate treaty (what became, in June 1992, the United Nations Framework Convention on Climate Change).  The denial and delay campaigns were kicking into gear (the so-called ‘Global Climate Coalition’ doing its predatory delay thing).  Part of the context for the whole climate awakening was how warm the 1980s had been (mild by today’s standards, of course).

What I think we can learn from this

The “warmest year ever” meme does not, on its own, ‘wake up the sheeple’.  If you want to have effective long-term action, you need effective long-term social movement organisations.

Also – shifting baselines are a thing.

What happened next

It kept getting warmer, as you may have noticed.

What do you think? Does this pass the ‘so what?’ threshold? Have I got facts wrong? Interpretation wrong?  Do comment on this post.
