Messing about with model-obs comparisons

I was just messing about with some model-observation comparison and just thought I would post some of the results. I don’t claim that I’ve done these properly, so use with care. I will, however, explain what I did, so that…

Doing science

This whole furore about Karl et al. has got me thinking more about how we actually conduct science/research. There is, I think, a perception that doing science/research involves following a fairly well defined set of procedures about which there should…

Effective Science communication?

I came across a post by Jon Tennant called science, echo chambers, and why facts are never enough. The basic idea is that people don’t really use science in rational ways, that publicly scientists can often end up mainly occupying…

Watt about four key charts?

I don’t look at Anthony Watts’s blog, Watts Up With That (WUWT), very often, but I glanced at it today and noticed a guest post called four key charts for a climate change skeptic. Anthony Watts’s pre-amble says Skeptics often…

A new baseline?

Ed Hawkins and colleagues have a new paper called Estimating changes in global temperature since pre-industrial times, which Ed also discusses in this post. The basic suggestion seems to be that we should probably be defining pre-industrial as the period…

Clutching at straws GWPF style

Since I have a few minutes spare I thought I would highlight another laugh aloud post from the Global Warming Policy Forum (GWPF). It’s about Arctic sea ice growing back to 2006 levels. Wow, amazing, what a turnaround after spending…

The warmest year…again

I haven’t, yet, written anything about 2016 becoming the warmest year in record. That’s partly because it appears to have been virtually certain that it would be for a few months now, and partly because it’s been extensively covered elsewhere.…

SpeedoScience

Talking about pseudoscience does not always bore me, but it often does. Not because it begs a far from obvious question, but because of its unsexiness. This kind of talk belongs to what I shall call, in honor of the …

Is it just basic physics?

I noticed a discussion on Twitter about whether or not, from basic physics, we know that most of the warming since the 1800s has been anthropogenic. Of course, it’s probably not basic physics, because it is quite complicated. However, I…

And so it begins!

Begins might be slightly wrong, as we’ve already had the David Rose saga, but it certainly continues. What I’m referring to is an article in the spectator by David Whitehouse (science editor of the Global Warming Policy Foundation) in which…

Public criticism

I came across an article about media and the game of climate change denialism. The basic message is that the media should better reflect the nuances in the climate change debate and should avoid presenting it as a debate between…

Big news in the climate blogosphere!

I guess the big news in the climate blogosphere is that Judith Curry has resigned (retired from?) her tenured faculty position at Georgia Tech. One reason appears to be that Judith is disenchanted with today’s academia. I actually have some…

Residual airborne fraction

Hope everyone had a good, and safe, festive season. Towards the end of last year I wrote a couple of posts about the ocean carbonare cycle. I then ended up in a debate about what it would take to stabilise…

2016: A year in blogging

Since the year is almost over, I thought I would summarise some of what has gone on here. January was a rather quiet month. I wrote about a poignant essay by Piers Sellers, who sadly passed away just before Christmas.…

Merry Christmas

Just a quick post to wish everyone a Merry Christmas (or whatever season’s greeting seems most appropriate). Given what’s happening in the Arctic, the cartoon on the right seems apt. I really do hope that everyone has a very pleasant…

Tipping Point

So the tipping point was social. That thought — a wrong one I hope — came to mind in the aftermath of a US election that set back prospects for reducing greenhouse gas emissions before major ecosystem or physical tipping…

Why should anyone care?

Steve Fuller, who is a sociologist at the University of Warwick, recently wrote an article in the Guardian called Science has always been a bit post-truth. I thought it was confused. Others were somewhat blunter I have rarely read a…

No, stabilising emissions will not stabilise concentrations!

I’ve written before about stabilising temperatures; stabilising temperatures requires getting net anthropogenic emissions pretty close to zero. See, for example, this Realclimate post, or Solomon et al. (2008). Stabilising atmospheric concentrations, however, would not require getting emissions to zero, but…

Rose down the rabbit hole

To follow-up on his previous article, where he claimed that stunning new data indicates El Nino drove record highs in global temperatures suggesting rise may not be down to man-made emissions, David Rose has a new article in which he…

They’re coming for climate scientists!

Doug McNeall had a bit of a tweet-storm yesterday about some personal thoughts on communicating climate science, which he titled So, they’re coming for climate scientists (hence, my title). It caused some discussion on Twitter, and on another blog, to…

Poor Roger!

I wrote a post about Roger Pielke Jr’s recent Wall Street Journal article about his [u]nhappy life as a climate heretic, but it was rather long and rambling, so I can’t actually bring myself to post it. Instead, I’ll just…

Open data

Since I’m sitting at the station waiting for a train that is delayed 40 minutes, I thought I would post on something that I’ve been thinking about for the last couple of days. There is quite a lot of discussion…

Prospects for narrowing ECS bounds

I was just going to briefly mention a new paper by Stevens, Sherwood, Bony and Webb in which they present [p]rospects for narrowing bounds on Earth’s equilibrium climate sensitivity. The basic argument is similar to what has – at times…

It woz El Nino wot dunnit!
