Certainty

There has recently been some discussion in climate change circles about climate sensitivity and predictions of warming trends about which I will not talk, as I have no expertise in those fields. However, as I am nevertheless trying to keep up-to-date, I recently read a reblogged blog post about just such issues on And then …

Tools for thinking about an increasingly complex world

A few weeks ago I had to write a seminar talk about epigenetics in the media. In the course of investigating the historical background to that emerging discipline, I looked at Conrad Hal Waddington’s work on embryology and development and his creation of the metaphor ‘epigenetic landscape’. But this is not what this blog post …

Global science, local perspectives – how does climate change fit into policy priorities?

I present here a  synopsis of a lecture I gave yesterday for year 3 undergraduates on our Climate, Science and Society module at University of Nottingham. The session was two hours long, which is rather a long time to listen to one person. So to ensure an engaged audience, I gave around an hour and …

Do online user comments provide a space for deliberative democracy?

This is a guest post by Luke Collins who is working with Brigitte Nerlich on an ESRC funded project dealing with climate change as a complex social issue. Yesterday, he gave talk about his research to an interdisciplinary audience attending the Institute for Science and Society/STS PG seminar series. The internet has enabled traditional newspaper …

Just one number: has the IPCC changed its supply of evidence?

As I have researched online climate scepticism over the last year, its become clear that climate sensitivity has been one of the biggest topics for discussion. This is perhaps one of the easier parts of climate science to understand. Put simply, sensitivity measures the amount by which the Earth’s temperature increases when atmospheric carbon dioxide …

Consensus on climate change: Tracing the contours of a debate

Soon the new IPCC report on climate change will be published (a leaked version is already circulating). This will probably generate a lot of talk about what one may call the four Cs: Consensus, certainty, confidence and credibility (let alone the other two Cs: climate and change). The discussion about consensus is already in full …

More heat than light? Climate catastrophe and the Hiroshima bomb

There has been some discussion on Twitter today (14 August) about the wisdom or otherwise of measuring the heat being retained by the Earth in terms of Hiroshima bombs. The analogy is presented by John Cook and Dana Nuccitelli on their Skeptical Science blog, drawing on an academic paper by Church et al to describe the heat …
