They know the truth, their public statements are an act. I think its pretty obvious that all public people say one thing and believe or do another in private.

> The current administration doesn't believe in climate change / global warming

Sure they do. None of the Greenland stuff (or most of the Canada stuff) makes sense unless they believe in these things.

We assume that if they believed they would try to slow these things down, but they chose a different path, profiting off the accelerationism.

The claims of not believing are just fodder for the FOX News/OANN watchers and what they say publicly is not what they believe.

In much the same way that David Miscavige doesn't believe in Xenu, I'm pretty positive Donald Trump does believe in global warming, he just doesn't care... or rather only cares insomuch as it is a profit opportunity.

> I’ve been puzzled why climate change messaging seems to ignore the emissions of other large countries like China and India.

It doesn't. The issue is likely more that you don't see or read widely enough.

Even here on HN you'll see mention of China and India's emissions and use of coal on a regular basis.

The US is a significant mention for two main reasons:-

* of all the human lofted additional CO2 of the past century plus (that sourced from formerly deep underground) the US is the single largest sole country contributor (although China is catching up (but may or may not equal the US)), ...

* the US is still a large per capita contributor today (ignoring tiny tiny outlier countries with small populations and near single export fossil fuel extraction countries) - it has an energy intensive economy.

My personal beef isn't so much with the US but specifically with US based fossil fuel and resource companies of the 1970s onwards (eg: Koch brothers) who were well aware of the problem with increasing the insulation factor of the atmosphere and doubled down anyway - spending large on "think tanks" to promote confusion via media, over sell the appeal of large cars, destroy any and all grass roots campaigns for public transport, etc. (CO2MaXXing ?).

The US has had influence across the planet post WWII, these campaigns just promoted a bad example for profit and deferred early and timely addressing of the issues.

Messaging over here does not ignore that. A big chunk in Australia is about stopping exports of oil and coal, or at the very least taxing the exports more and making it more expensive. You might have to listen to people and organizations actually concerned though, rather than politicians intent on doing the bare minimum to capture the climate vote.

The USA is far wealthier, uses more carbon per-person, and is responsible for more historical emissions than China or India. We have an obligation to reduce our gluttony before asking others to go without.

China and India have very, very low per capita emissions. They are also the countries working the hardest and fastest at installing renewable energy.

In the face of such incredulous hate, one must try to find some meaning to try and rationalize it.
