I'm starting to think that we're the baddies.

Ecologically speaking, the US is an absolute monster of a nightmare. The American carbon footprint is incredible.

For context, here are the top 10 biggest footprints

1. China 26.16%

2 United States 11.53%

3. India 7.69%

4. Russia 3.75%

5. Brazil 3.16%

6. Indonesia 3.15%

7. Japan 2.15%

8. Iran 2.06%

9. Saudi Arabia 1.60%

10. Canada 1.54%

The top 10 countries account for about ~60% of global CO₂ emissions.

Honest question, aren't coral reefs also very sensitive to climate change? How much of that loss is because of regional activities and how much is due to global environmental changes?

So, something has been bugging me. Coral is one of the oldest animals. They've been around for over half a billion years. They survived the Great Dying, which killed 80-95% of marine species. And now the ocean gets 0.9 C warmer and it's game over for coral?

0.9 C warmer on average vs location specific volatility + acidification

Ahem: "China consumes over half of the world’s coal and contributes more than 20% of global CO2 emissions from coal combustion." But trees are nice. Source: https://wires.onlinelibrary.wiley.com/doi/10.1002/wcc.918

is that per Capita? Also, At least they are going in the right direction with most metrics (switching to electric, installing renewable, planting trees, etc), whereas the US (under Trump) is hellbent on getting rid of renewables, focusing on coal/fossil fuel, slowing down electric cars, destroying national parks, etc.

Are you trying to say something like perfect is the enemy of good?

China has 4 times the population. In any rational divvying up of the world's total emissions allowance by country China's share would be 4 times that of the US, but they are only emitting twice what the US is emitting. Both are over their fair share, but the US is over by a larger factor so is farther behind on getting to where they need to be. (This is not taking into account trade. Divvying up the world emissions b…

Assigning blame and guilt is pointless. Just look at how well it has worked to motivate the US to change. That is to say, not at all. The only thing moving the needle is renewables and nuclear generating power more cheaply than fossil fuels, so it becomes stupid to not switch to them even if you have no regard for the long term health of the environment.

A huge portion of China's emissions come from making things for people that aren't in China. The argument is that if a Chinese factory makes only widgets used in the US, those emissions from the Chinese factory are probably more accurately counted as US emissions. Its like saying that you are 0 emissions because you have an electric car with no tailpipe while ignoring where the electricity is coming from.

The counter argument is that they'd have mass unemployment and would be in poverty without it. Virtually all rapid modern industrialization is reliant on exporting to foreign markets so characteizing it as American emissions is largely a misomer as it is really global emissions.

While I fundamentally disagree, do you really not see how that would then mean all Chinese emissions are therefore a result of the United States? So that's... worse?

US is far higher per capita and doing nothing about it.

This is one of the places where per capita doesn't matter as much as total emissions. We have one planet. The yearly total and cumulative matters the most. China is by far the leading emitter. Over double of the US as of 2023 (latest available data I can find). China's emissions also aren't falling, they are skyrocketing. The US emissions ARE falling. The US dominates in cumulative, which is essentially the measure o…

Per capita most definitely matters. Every human is equal, there is no reason why one human has the right to emit much more than another. If we go by your reasoning, then all developing countries should figure out how to raise living standards without consuming more resources so the Americans don’t have to reduce theirs.

You are incorrect that China isn’t doing anything to lower its impact. It’s emissions would be much much much worse for the standard of living increases it achieved without investments in clean energy and EVs, tech that it is exporting abroad to the benefit of the world and to the dismay of America’s petro dollar dependence.

With such thinking, I now get why the rest of the world is beginning to hate America so much.

Cities tend to expand up. Almost all buildings in Mumbai that are under 5 stories are targeted for "redevelopment" i.e. a developer buying it out and building something taller in its place.

That is too costly for cities that have cheap and abandoned agricultural land waiting to be deforested and build upon.

The time / distance of commute is a natural limiting factor.

Considering that China is responsible for ~25% of cumulative CO2 emissions to date, there's not much difference between the regional and global inputs.

Isn't this 75% less responsibility than total responsibility in case it's only due to regional activities?

My guess is as a species it will relocate to somewhere with the right temperature zone but because coral takes so long to grow from the perspective of those of us alive the existing “old growth” coral will die.
