2015 blog summary

Posted on December 31, 2015 by ...and Then There's Physics

I realise that I’ve already written a review of 2015, but partly as a result of Willard’s comments, and partly as a result of Stoat’s post, I realised that I hadn’t really summarised the blog activity. So, here it is; … Continue reading →

2015 in review

Posted on December 29, 2015 by ...and Then There's Physics

Since I have a few free moments, I thought I would briefly review what’s happened in 2015. If you want something a bit more thorough, you could read Greg Laden’s or Skeptical Science’s reviews. After 2014 was the hottest year … Continue reading →

Zero emissions

Posted on December 26, 2015 by ...and Then There's Physics

David Roberts has a recent post that I’ve only just noticed called why zero is a better climate target than 2 degrees. The zero refers to net global emissions, not to temperature. The argument is essentially that zero is a … Continue reading →

Merry Christmas

Posted on December 24, 2015 by ...and Then There's Physics

Posting has been rather light recently, and I expect that to continue for a while. I’m quite enjoying doing other things, but I suspect I’ll be back to posting in the not too distant future. However, since it’s Christmas Eve, … Continue reading →

RCPs as scenarios

Posted on December 17, 2015 by ...and Then There's Physics

Fabius Maximus has a guest post on Climate Etc. in which he focuses on RCP8.5. RCP8.5 is a Representative Concentration Pathway (RCP) that leads to a change in forcing of 8.5Wm-2 in 2100. Focusing on this particular RCP seems to … Continue reading →

Forcing efficacy

Posted on December 15, 2015 by ...and Then There's Physics

There’s a new paper, discussing climate sensitivity, by Marvel, Schmidt, Miller & Nazarenko called Implications for climate sensitivity from the response to individual forcings. Before I discuss the paper, I should really advertise the lead author’s blog, arguably one of … Continue reading →

Pragmatism

Posted on December 14, 2015 by ...and Then There's Physics

It’s been interesting to see the different responses to the Paris agreement. James Hansen calls it a fraud (Richard Erskine thinks he’s wrong). Kevin Anderson is a bit more measured. Others are more positive and optimistic. I find myself sympathysing … Continue reading →

Consilience of the evidence

Posted on December 13, 2015 by ...and Then There's Physics

I was wanting to briefly highlight a David Roberts post called the two key points that climate “skeptics” miss. I was only going to comment on one of the points, which was about the convergence of all the evidence, typically … Continue reading →

1.5C?

Posted on December 12, 2015 by ...and Then There's Physics

I think that the negotiators in Paris are pretty close to reaching an agreement (may have already done so). There’s a draft version here. Maybe the most interesting aspect of the agreement is the paragraph below: Emphasizing with serious concern … Continue reading →

Dogma?

Posted on December 9, 2015 by ...and Then There's Physics

I watched some of the Congressional hearing yesterday on Data or dogma? It consisted of evidence from four people who I shall politely describe as contrarians (Judith Curry, John Christy, William Happer, and Mark Steyn) and one person who had … Continue reading →
