Le chiffre de +2-3°C de réchauffement en ville en pleine canicule à cause de la clim a pour origine cette étude (Viguié et al 2020), écrite par des chercheurs de diverses institutions (CIRED, CNRM, CSTB), et publiée donc en 2020 :

Do you mean something like "maths wants to be free and open source and most mathematicians agree that's a very important core value, and it is perverse to pay them to take their thoughts out of the public domain" ?

What does it mean ? 100 percent real question

A screenshot of an ebook, which reads: "In all these cases, the outcome of the CBA or another quantification exercise will have a misleadingly reassuring precision. Decision makers may understandably take this precision to mean that they can confidently rely on the recommendation of the CBA, when in fact it is no more reliable than the dubious numbers on which it is based. The situation is reminiscent of an apocryphal story about weighing hogs in Texas.

'Down there, they put the hog in one pan of a large set of scales, put rocks in the other pan ... until they exactly balance the weight of the hog. Having done that very carefully, they guess how much the rocks weigh.'"

I'd love it to show solar PV for comparison

I hope that is true! Cannot help but wonder if the snowstorm is part of the reason

- a dollar spent on mitigation yields most in a rich country, while a dollar spent on poverty reduction (kind of the same thing anyway) yields most in a poor country
- the accounting of climate adaptation finance tends to exclude normal development finance for political reasons

Adrien Vogt-Schilb @vogtschilb.bsky.social · Dec 24

To be sure I quoted that, but the whole piece is littered with what everyone seems to need to read about climate finance
-adaptation consists of my mostly private or locally public goods easy to fund, but impossible to measure
- mitigation is a global good but is mostly provided by private goods

"the misapprehension that because two things are both good things for the world...they need to be tackled together" 👌

The first words of my final blog for CGD before starting as Deputy Chief Economist at FCDO:

“Climate finance is a disaster.”

But the problem is not that there isn’t enough of it. It’s far worse than that. It’s that none of it makes sense, and we’ve designed it in a way that minimises its impact.

Is Climate Finance Fixable?

Climate finance is a disaster. COP29 ended with a hotly-contested and almost universally-loathed agreement for rich countries to provide $300 billion each year to developing countries, to defray the c...

How do public policies stack up? Is the impact of two policies larger than the sum of its parts?

We look at this in the context of food - labels + price policies - & find they are *extremely* sub-additive.

Also, labels do way better than prices.

Denver gave people experiencing homelessness $1k/month. A year later, nearly half had housing.

They also had fewer ER visits, nights spent in a hospital, and jail stays.

The report estimates that this reduction in public service use SAVED the city $589k.

Denver gave people experiencing homelessness $1,000 a month. A year later, nearly half of participants said they had housing.

Participants in Denver's basic-income program reported having more-secure housing, though results were similar in the trial and control groups.

Thank God. Those footnotes were tedious.

A little paragraph in the NCQG text with important accounting effects:

Under $100bn goal, because MDB shareholders are developed + developing, only 71% of MDB climate finance counted.

Now all MDB climate finance counts. At current levels, this means $21 billion more counted towards NCQG per year

"aid shouldn’t be diverted away from high return projects in the poorest countries in order to help rich countries build a façade of global climate solidarity". Bold !

Charles Kenny @charlesjkenny.bsky.social · Nov 24

Rule number one for climate negotiators should be ‘don’t make poor people pay twice for climate.’ The gathering in Baku utterly ignored that in the rush to a big number.
