Twenty years ago, on this day, February 10, 2006
“On February 10, 2006, the Friday of the week that George Deutsch resigned, Jim spoke at a conference on politics and science, sponsored by the New School for Social Research in Manhattan. (He was added at the last minute on account of his recent notoriety.) IN a talk derived from the Keeling talk, which was now about two months old, he decided to add a brief discussion of tropical storms, because the topic was “especially relevant to this conference.”
See these two pages from Mark Bowen’s Censoring Science: Inside the Political Attack on Dr. James Hansen and the Truth of Global Warming.


2006 Hansen at conference on science and politics at New School for Social Research (Bowen Censoring Science page 143)
The amount of carbon dioxide in the air was roughly 382ppm. As of 2026 it is 428ppm, but check here for daily measures.
The broader context was that Hansen had been abused, ignored, sidelined in 1989 by the George HW Bush administration, and had basically gone back to the lab (that’s no criticism of the man, btw).
The specific context was that by 2006 the climate issue was heating up again – the Kyoto Protocol had been ratified (thanks, Russia) – so the international negotiations were “back on”, the European Union Emissions Trading Scheme was underway, and Al Gore’s film was about to come out.
Last summer (2005) Hurricane Katrina had hit New Orleans, with thousands dead.
What I think we can learn from this is that the Bush regime was full of assholes.
What happened next: Hansen started getting arrested at protests about coal plants and pipelines, and has kept on with the science.
What do you think? Does this pass the ‘so what?’ threshold? Have I got facts wrong? Interpretation wrong? Please do comment on this post, unless you are a denialist, obvs.
