Yes, they were. I think we arrived after the tipping point had passed. That was 4 years ago, and there were no adverts for any ICE vehicles at all - I remember this being different to France/UK at the time...

It's not giving me 'social tipping point' vibes yet...

This kind of thing normally takes months/years to execute in its entirity. Nothing like the pressure of CMIP deadline to focus the mind(s).

I think it's quite land-centric, tbf (given it's me and Kjetil he's talking to ;) )

I learned last week that one of my great great grandparents and their forebears were from Shap. This made me enormously pleased.

I don't do anything, tbf. There's pretty much nothing in my research output on 1.5C...

Sorry, but your logic is not very clear. How will delaying net zero targets make any difference to what Russia does? Are those things strongly coupled? Why?
And whose national interest are you assuming I am batting for here??

So you are in the "do nothing now because it's hard, and leave it to our kids to sort out all the mess" camp? Just to be clear... (mass extinctions and coral death and fires and droughts and crop failures and heatwaves notwithstanding? )

1.5C is what we think we need to avoid "dangerous" climate outcomes in the natural climate system. Which does not care about your S-curve and your national security and your computer chips. llustrating how far away we are from that seems perfectly reasonable to me.

I am not sure why national security in the Baltics nor having chips from Taiwan is at all incompatible with ambitious climate targets? Climate change causes its own threats to national security, and the solution on the table generates rather than erodes energy independence. Ideology works both ways.

I am not quite sure why you are so worked up over this plot. We aren't on track for 1.5C and this plot make that very clear...

What, I personally should drop it? Sorry, but I don't think that would have all that great of an impact... But maybe try explaining your position to all the countries who will be underwater >1.5C and see how 'normal' they think your perspective is...

It is not 'suddenly' the benchmark. 1.5C is the basis of the Paris agreement and so scenarios that meet them have been the benchmark for the last 10 years.

and also, by way of illustration, of the 25-30 awesome and hardworking people who are involved in finalizing NorESM right now, probably only about 2-3 of them are on any social media at all...

...or analysing the output of models that other people made 20 years ago ;)
I guess this is kindof my point. No-one doing this has time to talk about how hard it is. So the sheer amount of work and thought and creative problem solving and focus and perseverance involved goes rather under the radar.

Same for veg models in my limited experience.
And, at interview, when you’re asked where all your first author papers are and you say, eh but…veg model (see code), it doesn’t count.
It doesn’t count like it should to do really hard things. I should have stuck to stats.
Sorry, mini rant over 🙈
