Assume we hit 1.5C and "nothing happens" does this help the cause? While I'm very concerned about how unchecked climate change could impact future crop yields I also worry that having a hard line like this probably won't help convince anyone, and could counter intuitively act as a "I told you so" for climate denialists when the world doesn't fall apart as soon as we hit 1.5C. A lot of the more convincing arguments I…

> A lot of the more convincing arguments I hear from climate denialists (I hate that phase btw) is that past climate models have been highly inaccurate and many claims and concerns have in time been proven overstated. That's such a trite reply. First, we can take it literal. Yes, models have been inaccurate, and this one will be too. The trend is unmistakably there, though. You can check the bloody weather outside to…

I agree with everything you're saying.

I tend to operate with two mental modals because I believe a lot of these divides can be explained by differing educational levels and intellectual abilities.

I think you need to put yourself in the headspace of a 90 IQ dude who has been told his entire adult life that the world is going to end because of climate change. To him the fact that there was snow the other day and the world hasn't yet come to an end is actually a convincing argument that the Earth isn't getting so hot that he needs to be concerned.

Similarly, while this hypothetical person might not be intelligent enough to understand that scientific models are always going to have some level of inaccuracy and there is always some amount of noise in the data, they are intelligent enough to recognise that in the past false claims have been made – and often these claims have been made in a condescending manner.

We've seen similar divides and misunderstandings with Trump, Brexit and the pandemic. We need to find better ways to communicate across social divides – that's what I was appealing to. We have to do a better job at presenting data in a way that's accessible to every while also not being so condescending and overly opinionated that it's off putting to those who remain unconvinced.

Or put another way, a climate denialist isn't going to be convinced by you telling them they're an idiot for not understanding how to analyse the data correctly (even if you're correct). You instead have to recognise the merits of their perspective and try to explain the data in a way that will allow them (hopefully) to come to the correct conclusions.

But like I say, I don't know if this is even possible with climate change. A lot of people I'm referring to here think with their eyes and if they can't see the truth in their own life experiences, and with their own eyes, then they're sceptical of it. Climate change for lots of reasons is unfortunately one of those things that's really difficult to explain to someone who sees snow as evidence of that the Earth isn't getting hotter, but these are the people we ultimately need to convince.

> Do you want to bet your life and the lives of the ones you and we love?

No. That's why I'm saying please stop with the alarmism. It doesn't convince anyone and just causes unhelpful ideological divides.

Coal is only going out of style because we are building out new natgas plants. The greatest trick that has been pulled on us this century is somehow billing gas as a 'green' source of energy. Electric cars are an expensive distraction from the problem. The sustainable future of transportation is the electric train, the electric trolley, the electric scooter, and the electric bicycle. Personal automobiles, electric or…

> The greatest trick that has been pulled on us this century is somehow billing gas as a 'green' source of energy. Gas has significantly lower emissions than coal. Progress is progress. Absolutism gets us nowhere, unless your goal is to drive humanity back to the stone age by "switching" to energy production systems that do not currently exist (with the exception of nuclear, which is the only currently practical solu…

> Absolutism gets us nowhere,

And building out natgas will get us into a situation where we are locked into decades of guaranteed emissions, as all the vested interests in the production and consumption space fight tooth and nail to protect their line of business, and the capex they've dumped into it.

There's no plausible net-carbon zero path this century that's compatible with our current buildout of natgas. Perfect is the enemy of the good, but this isn't even good!

Not the GP, but sure, if the people making those wrong predictions are advocating for policy changes that will impoverish so many people.

Climate change is already impoverishing people.

Not as many as cheap energy from fossil fuels are lifting the global poor out of poverty.

The comparisons between the AR5 and AR6 are alarming. Now, under no emission scenarios other than low and very low which we are not tracking close to, we reach +2C at or just before 2050. Many reading this thread will see 3 degrees by the time they plan to retire. This comes with drought, undernourishment, and mass migration: https://sciencenorway.no/climate-climate-change/deadly-heat-...
