The Primacy of Doubt

Recently Judith Curry published a series of articles on the topic of blackouts. Since attempting to prevent such things is my “professional” speciality I’ve spent a bit of time over at “Climate Etc.” recently. Hence I couldn’t help but notice Judith’s article on Tim Palmer‘s new book, entitled “The Primacy of Doubt”. According to Judith:

This book is a physics-intellectual feast.  Must read.

Hence I immediately rushed online and bought a copy from amazon.co.uk, which arrived today. A more detailed overview will follow once I’ve had a chance to read the whole book, but leafing through it this evening I couldn’t help but notice this quotation from Richard Feynman at the very start:

Our freedom to doubt was born of a struggle against authority in the early days of science. It was a very deep and strong struggle. Permit us to question — to doubt, that’s all — not to be sure.

My gaze also alighted on the final paragraph of chapter 10 – “Decisions! Decisions!”:

Just as with weather prediction, a cost-loss analysis can help you make a decision about whether to take anticipatory action regarding climate change…

Based on the way we value our own existence in other areas of life, there does indeed seem to be a strong argument that we should act now, uncertainties about future climate change notwithstanding.

But this is ultimately a decision which each of us must make, e.g. in deciding which politicians to vote for.

Of course being a citizen of the once Great British banana republic I don’t get to vote on our next Prime Minister!

I think I’ll go and pass this news on to Judith and her denizens forthwith. Meanwhile here’s a quotation from the back cover. According to Suki Manabe, winner of the 2021 Nobel Prize in Physics:

The Primacy of Doubt is an important book by one of the pioneers of dynamical weather prediction, indispensable for daily life, describing how the approach can be used for prediction in other areas, such as climate, health, economy, and conflict.

I’m still rather busy trying to help keep the UK’s lights on, so I have yet to even begin reading “The Primacy of Doubt” from cover to cover. However here is another brief extract, from the chapter on “Climate Change”:

We understand these [water vapour, albedo] feedback processes reasonably well. However, there is another feedback process associated with water that we understand rather poorly. This is the cloud feedback process.

[Edit – October 25th]

Here’s another extract from chapter 6 (page 115):

The question of whether clouds act as a positive or negative feedback on climate change can’t at present be answered unambiguously: indeed, I would say it is the biggest unsolved problem in physical climate-change science.

Rewriting The Arctic

Peter, a welcome new denizen here at the Great White Con Ivory Towers, appears to have parachuted into our far north summer hideaway on the shores of Santa’s Secret Summer Swimming Pool straight from Tony Heller‘s Unreal Climate Science blog.

Prompted by Peter I wandered over to Tony’s place where I found to my surprise that he has recently been busy warming up an old chestnut of his that has been debunked numerous times over the past decade. Allegedly:

Between 1990 and 2001, the IPCC rewrote the Arctic sea ice satellite record, and changed a trend of ice increasing to ice decreasing.

Here’s a previous chestnut rewarming event preserved for posterity:

Sadly Tony’s side of the “debate” has been deleted by the powers that be at Twitter, so here are the two graphs in question, combined by Mr. Heller into one illuminating animation:

I posted this comment on Tony’s blog last night (UTC), but he hasn’t got back to me yet:

Neither has anybody else. That’s probably because this morning my words of wisdom are still only visible to Tony and I?

Progress at long last! Vegieman directs the attention of Tony’s band of merry (mostly) men to:

However for some strange reason he neglects to mention that Tony’s link labelled “2001 IPCC Report” doesn’t lead to that graph!

Not a lot of people know that since things have gone quiet at Tony’s place I popped into Paul Homewood’s echo chamber, where rewriting the Arctic continues apace:

Needless to say my helpful comment is currently invisible.

Facts About the Arctic in October 2022

The 2022/23 freezing season has begun, so to begin with here are Arctic sea ice area and extent during its early stages:

Both metrics are currently tracking 2021 quite closely.

Here too is an AMSR2 animation of the transition from melting to freezing in the Central Arctic. Click to animate, and be warned that the file size is almost 10 Mb:

Another big storm is heading for the Chukchi Sea. The GFS forecast currently shows a sub 960 hPa low developing on Thursday:
