If we don’t do something about this, I fear future generations will not view us in a positive light.

On the path we're on I don't think we'll have to worry too much about future generations.

The EU has already seeing 10,000 excess deaths from climate changed caused heat waves and this is a minuscule taste of what's to come.

A very large percentage of mass extinction events have their roots in increased atmospheric CO2, but all of them on dramatically increased time scales. The closest thing in the history of the planet to what's happening to day was PETM [0] and that was only a lessor extinction event because the Earth was already quite warm (for example, there was already no polar ice at the time).

What is Western Europe's #?

1.1 GT combined but shrinking yearly by 1-3%, which isn't enough to make up for the combined increase in carbon emissions from India, ASEAN, MENA, LatAm, and Russia.

Are those domestic emissions only? Or do we include emissions from purchasing goods from other countries?

> If we don’t do something about this... We can't. We're too late. China (13 GT), the US (4.6 GT), and India (3 GT) alone represent 51% of global carbon emissions - and at least in India's case, it is growing at a rate of 5%. Throw in other large polluters like Russia (2 GT), Indonesia (0.8 GT), Iran (0.8 GT), KSA (0.6 GT), Brazil (0.5 GT), and Vietnam (0.5 GT) whose rate of carbon emissions is growing in the 5-10% r…

They're not rendered useless. Do you argue the same way about voting too? Ultimately consumption is 2/3s of all emissions, and the majority of it is not billionaires.

Are you saying that no billionaire profits from the consumption of others? And, if some do, do they not maximise that profit by seeking to maximise the consumption of others?

I say no such thing.

Is the major issue here that 3 degrees Celsius is like an average so all the hot tropics places just become uninhabitable whereas temperature rises are more moderated in higher latitudes? Also how much faster and higher will that number go with all the data centers? Can't imagine it not just getting worse.

One major issue is the extreme difficulty of being precise about tipping points. Eg: Have you seen a train derail? A couple of degrees of tilt - nothing .. and then .. whoops. The global climate has been 'stable' about mean values for the bulk of human written history and development of urban civilisations. The planet now hosts 7 billion+ people, largely urban, and feed by a century of stable agriculture patterns wri…

But there have been way higher atmospheric carbon dioxide levels historically, and those have largely coincided with plant and animal life climaxing. See the Jurassic.

You conveniently left the US out of that and the US's role in driving global emissions. China is also likely rapidly de-carbonizing right now just like they rapidly spun up. They are an issue, but the US and its policies have a massive impact on this problem. Same with Europe. Rapidly adopting renewables and not externalizing our emissions to other countries would go a long way. I have seen the argument shift from 'T…

> China is also likely rapidly de-carbonizing right now Huh. "China’s carbon dioxide (CO2) emissions fell by 1% in the final quarter of 2025, likely securing a decline of 0.3% for the full year as a whole" [1]. So "rapidly de-carbonising" is wrong. But decarbonising per se is correct. [1] https://www.carbonbrief.org/analysis-chinas-co2-emissions-ha...

Chin's emissions rose by 20% from 2017 to 2024 and then flat-lined in 2025 with emissions expected to decline in 2026. That is what decarbonization looks like, the rate of change has swung massively in the right direction. The .3 in 2025 will likely turn into -1.5 in 2026 and more after that. They have embraced alternative energy because it is now making them money and gaining them influence. That trend won't change and they will keep on decarbonizing because it is the easy, profitable, route.

UK official body of actuaries basically says we are on trajectory of "Extreme" rating: > 3°C or more by 2050. Multiple climate tipping points triggered, tipping cascade. > over 4 billion deaths If so, big shifts would already be imminently felt within next 5-10 years. Remember that there would basically be no place to hide from these direct or knock-on effects. Not for any self sufficient "prepper with a Mac Studio"…

> there will basically no place to hide from these direct or any knock-on effects This is nonsense. (And your own source doesn't support the claim that the consequences of global warming will be unmitigable for anyone.) Many parts of the world will become milder for human occupation as a result of climate change. And nothing realistically forecast is unavoidable with wealth–rich countries will A/C and seawall their w…

The effects would definitely be felt by everyone if the global population were on its way to be halved. Also knock-on effects like mass emigration putting additional pressure on an already difficult political landscape. Potential for many more wars; more unknown unknowns etc.

Edit: the report’s "Extreme" severity band is indeed not a forecast but they’re basically saying "the chance of this happening is way too high".

Overall emissions.

But the UK and EU (the only large polluters who have even considered carbon tariffs) have largely watered them down - for example, yesterday with the UK increasing it's duty free steel quota for India [0] as Tata Steel owns much of the UK's steel capacity and demand (JLR is a Tata company). Add to that the EU's largest steel maker is owned by India's Mittal family (AcrelorMittal) and European conglomerates like Renault [1] are expanding manufacturing in markets like India, which means using Indian steel.

And all of that ignores domestic growth in all those countries. Base GDP growth rates are expected to be in the 6.5-8% for India and ASEAN despite deglobalization because domestic markets are growing.

We _are_ doing something about this. We’re locating concentrated millions of years of trapped fossil energy and moving it into our atmosphere as fast as we possibly can. To a first approximation, that is the world economy. Or did you mean to do something differently?

Both Europe and US's emissions are significantly (18%-30%) below their peak (which was 20 years ago. The rest of the world is also moving towards renewables.

How much of that is just outsourcing much of our industry to Asia/etc.?
