Excellent advice on paper review:

1. Peer reviewers are volunteers.

2. Map all comments to actions.

3. Address all comments.

4. Focus on improving your paper, instead of arguing.

5. Rarely, and only with strong defense, say no.

6. Don’t take things personally.

7. Avoid recreational revisions.

Excellent by @spignal.bsky.social, on European politicians using Brussels as a smokescreen and scapegoat.

'[G]iven that national governments form the backbone of the eu, “blaming Brussels” is akin to a ventriloquist haranguing his own puppet for being foul-mouthed.'
“Brussels” is the phantom menace Europe loves to blame
Why bashing the EU is likely to become ever more popular

The same article includes a reference to an @swp-berlin.org paper that does not exist.

There are many ways AI can support research, but just letting it write your articles with fake citations certainly is not the way.

Tomorrow I will give the opening talk at the Nesta event "What can we learn from Sweden's rollout of heat pumps?".

Here's one key take-away: Sweden has one of the lowest electricity to gas price ratios in Europe.

That is a key factor when it comes to heat pump adoption.

German Reunification Day invites both gratitude and reflection.
Gratitude, because the peaceful revolution of 1989 was nothing short of a miracle — a bloodless dismantling of a repressive regime.
Reflection, because the wounds of the transition still mark the country —and because

A fireball lit up the sky across the Los Angeles area on Thursday night after an explosion at a Chevron refinery in El Segundo, alarming nearby residents who said it felt like an earthquake. The cause of the explosion was not clear. No injuries were reported. nyti.ms/42pPCaW

35 years ago, on October 3, 1990, Germany was reunified. Just two months later, voters in the former GDR went to the polls in the first free federal election since the Weimar era. Despite decades of socialist dictatorship, East German voting behavior displayed marked regional differences. Thread🧵

This recent working paper by @rmetcalfe.bsky.social e.a. for @centrefornetzero.bsky.social shows how effective automated EV smart charging is:

"42% reduction in household electricity demand during peak hours, with 100% of this demand shifted to low-cost, low-emission off-peak periods."
Figure shows electricity consumption throughout the day for a baseline and with an EV tariff. During the off-peak period in the middle of the night, consumption is much higher with the EV tariff, while during the peak in the early evening it is much lower.

Food production is the primary driver for breaching 5 of the planetary boundaries & accounts for ca. 30% of global emissions, while billions still lack access to healthy diets. New EAT Lancet report with PIK director Johan Rockström & EAT Forum out now!

Help colleagues!

Does anyone have good references on how in the transport sector we tend to fall prey to the "hype cycle" and keep having unrealistic expectations that new technologies will "change everything" or even "solve everything" in our sector?

Hauptpunkt des Vorschlags (um den es mir geht) ist doch, dass Flächen- durch Strommengenziele ersetzt werden sollen.

Die Ministerpräsident:innen der ostdeutschen Länder wollen die Flächenziele für die Windenergie durch Ökostromziele ersetzen. Warum das eine problematische Idee ist, habe ich vor ein paar Monaten im Thread unten ausgeführt.
