Looking into the numbers a couple if months ago I was surprised how little it costs to stop climate change.

On the order of 100-200 trillion USD. Which is roughly 100-200% of global yearly GDP. Or 2-5% of yearly GDP until 2050. This could well be provided by printing money at all the federal reserve banks.

This investment will likely bring in a positive return on investment because it reduces the negative climate impacts.

Without such investments the downstream costs in climate change adaptation will be very expensive

If you're referring to he economist one, I've read it too, and I think it would be much cheaper.

But anyway, I don't believe half the numbers out there.

To cut emissions, we need to kill materialism, consumption economy and most importantly tell people that they should choose between what's good for them (eating a burger to make them happy) or the planet (not bringing the equivalent pollution of driving an SUV 50 miles+ by eating something much less polluting than beef).

Governments will keep chasing the kind of changes that can only make more money, not less.

About half of CO2 emissions are electricity, heating and transport. Not beef.

And for those we have viable solutions that either do not lower subjective quality of living or even improve it, but they are not sufficiently implemented by enough people.

Telling folks to stop eating beef now is compounding the problem by making people just give up.

We should first address the things that we have viable solutions for instead of loosing public support by insisting on reducing emissions in areas where there are no good solutions yet and some sort of asceticism seems to be in order.

Methane is between 30 and 200 times more dangerous than CO2 and a single cow produces 200 pounds of it per year.

Another fun fact: the mass of all cattle on the planet is higher than all other animals combined. All of them from cats to rhinos and wild horses.

That's exactly my point: the real issues aren't related to government policies related to just focusing on CO2 emissions from energy but how much and what we consume.

What we eat, by far, is the element that most impacts the planet. By far. The others, besides using more public transport are very small.

But nobody wants to hear or face it because it implies how we live and eat.

Hell a single cotton shirt requires 2000 liters of fresh water, a scarce resource, I don't see as much arguments about how we consume but plenty of neverending EV and electricity gaslighting.

It's much simpler to point at vague problems

No it isn‘t.
