20 years of hockey sticks

It’s almost 20 years since the publication of the first hockey stick paper (Mann, Bradley & Hughes 1998). In case people don’t know, the hockey stick refers to a temperature reconstruction that indicates that surface temperatures had been reasonably flat,…

The “truth” matters

There’s been a lengthy Twitter exchange about the Harvey et al. paper. In case you don’t remember, it was a paper essentially arguing that those blogs that tend to be dismissive of the risks associated with anthropogenic global warming (AGW)…

Five years

Turns out today is the fifth anniversary of me starting this blog. It’s been an interesting journey and I feel that I should reflect on what I’ve done, what I’ve learned, what I would have done differently, and what I’m…

Criticising the critics

I’ve recently come across a number of examples of people objecting to the manner in which some people engage in public criticism. There is a podcast with Sam Harris and Ezra Klein. It relates to a situation in which a…

Some impacts of warming by 1.5 and 2C

Something I’ve always struggled with when it comes to climate change is understanding the actual impacts of anthropogenic global warming. I think I understand the big picture quite well. If we continue to add greenhouse gases to the atmosphere, we…

An editorial response

Our response to Hermann Harde’s paper has finally appeared. What’s maybe more interesting is that there is also an editorial response by Martin Grosjean, Joel Guiot, and Zicheng Yu. It’s already been discussed at Realclimate and Rabett Run, but there…

The climate of the past

Richard Alley and Gavin Schmidt, currently two of the best climate communicators, recently gave presentations at the Smithsonian Institution, National Museum of Natural History, about how we study paleoclimate and how this understanding can help us to project what will…

The Paris climate targets

I’m currently in Oxford for a meeting and, having spent most of the train ride working on a book chapter I’m writing, I thought I would now spend some time writing a quick post about the recent Schurer et al.…

Flying

I noticed another discussion on Twitter about whether or not climate scientists should fly. I have written about this before and the issue of people making personal sacrifices is something I’ve pondered recently. I have a great deal of respect…

Moderation

I don’t particularly like discussing moderation and, in fact, it’s been much less of a problem than it once was. However, for various reasons, I thought I would quickly stress something about how, and why, I run this blog. I…

Ignoring adaptation?

Oren Cass has an article in the Wall Street Journal called Doomsday climate scenarios are a joke. It’s based on a report that he has written for the Manhattan Institute. The Manhattan Institute publishes a magazine called the City Journal…

Living in Liquid Worlds

I spent yesterday at a workshop – organised by Dominic Hinde – at the Institute for Advanced studies in the Humanities. The title of the workshop was Living in Liquid Worlds. The idea was to bring together scholars from different…

Talking solutions and motivating action

There’s been a lengthy Twitter discussion about scientists moving away from simply discussing the science of climate change, to talking about solutions and motivating action. I broadly agree with this; I do think that the main discussion should be about…

Long-term climate goals

There was quite a lot of coverage last year about a paper by Millar et al. which suggested that the carbon budget that would keep warming below 1.5oC was greater than had been earlier suggested. I wrote about it here,…
