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.

Watch this space!

The 2021 Nobel Prize in Physics

Here’s this morning’s announcement of The 2021 Nobel Prize in Physics from the Royal Swedish Academy of Sciences in Stockholm in full:

The associated press release puts it this way:

The Royal Swedish Academy of Sciences has decided to award the Nobel Prize in Physics 2021

“for groundbreaking contributions to our understanding of complex physical systems”

with one half jointly to Syukuro Manabe, Princeton University, USA and Klaus Hasselmann, Max Planck Institute for Meteorology, Hamburg, Germany

“for the physical modelling of Earth’s climate, quantifying variability and reliably predicting global warming”

and the other half to Giorgio Parisi, Sapienza University of Rome, Italy

“for the discovery of the interplay of disorder and fluctuations in physical systems from atomic to planetary scales”

The press release explains:

What’s Up With That Arctic Sea Ice Disinformation

A few days ago we posted an article about the recent surge in the amount of disinformation being published about Arctic sea ice. Eventually one of our long list of usual suspects, Anthony Watts, published a copy of an erroneous Arctic article by Paul Homewood.

Now the Watts Up With That Arctic porky pie production line is going into overdrive, so here’s an already long list of its output in the run up to the COP26 conference in Glasgow in a month or so. First up is the aforementioned clone from NALOPKT. Allegedly:

It is very easy to show that Arctic sea ice has stabilised. As their graph itself shows, there have only been three years since 2007 with lower ice extent than that year, and eleven have had higher extents. Also the average of the last ten years is higher than 2007’s extent.

In itself, this is too short a period to make any meaningful judgements. But that is no excuse for the Met Office to publish such a manifest falsehood.

This comment of mine on that article remains invisible at WUWT:

This morning (UTC) I added another comment to Anthony’s moderation queue:
