May 9, 1959 – “Science News” predicts 25% increase of C02 by end of century (Bert Bolin’s guesstimate)

Sixty five years ago, on this day, May 9th, 1959, a popular science journal, Science News, covered the findings of Swedish climate scientist Bert Bolin. The amount of carbon dioxide in the air was roughly 316ppm. As of 2024 it is 425ppm, but check here for daily measures.  The context was that Bolin had been […]

May 6, 1977 – Bert Bolin article in Science about increased atmospheric CO2 concentrations owing to forestry and agriculture

Forty seven years ago, on this day, May 6th, 1977, Swedish scientist Bert Bolin sounded a warning about other sources (besides burning oil, coal and gas) leading to more CO2 in the atmosphere.

December 30, 2007 – Bert Bolin dies.

December 30, 2007 – Bert Bolin dies. He was a Swedish scientist, did more than anyone else (I would argue) from the 1950s to the 1980s to get carbon dioxide build-up on the political agenda (he was most certainly not alone in doing this – proper group effort). Find posts about him on this site […]

April 1, 1960 – TIROS satellite launched

Sixty four years ago, on this day, April 1st, 1960, a weather satellite started being like the wheels on the bus (i.e. going round and round). On 1 April 1960, the USA launched its first meteorological satellite, TIROS 1. It was a remarkable experience for people to be able to view the earth and its […]

January 1970 – Yale biologist muses on science, politics, pollution, warming.

In this month, 54 years ago, eminent Yale biologist G. Evelyn Hutchinson reflected on the effectiveness of Senate hearings for investigating environmental dilemmas, including carbon dioxide build-up. “Though dire effects on climate of an increase in CO2 have been predicted, this is far from being adequately established (5). The cycle is not really fully understood, […]

On getting things wrong – a meditation and apology

First thing is – I screwed up, and there’s absolutely nobody else to blame. I posted yesterday this blog post. It’s something that I wrote the first draft of a year ago, and had updated at some point since. The problem with it is that the quoted scientist, Mike Pentz, was not warning about C02 […]

Sixteen years ago, on this day, December 12, 2007, the important US climate scientist William Kellogg dies; as with Bert Bolin, very good timing both The amount of carbon dioxide in the air was roughly 384ppm. As of 2023 it is 421ppm, but check here for daily measures.  The context was that William Kellogg had […]
