This is why Co2 do not have any effect until it reaches the high troposphere. That takes 20 years. The average climate we have right now is caused by emissions from 2003.
I'll repeat that in the comments of every climate article I read by the way, sorry for the repetition. M
CO2-extraction takes energy though, quite a lot of it. Using energy from fossil fuel for CO2-extraction is worse than doing nothing, since you're never going to extract as much CO2 as is emitted by the power plant. That leaves using clean energy, but clean energy is a limited resource. Using clean energy to replace current uses of CO2-emitting energy is likely going to be more effective than using it to extract the emitted CO2 back out of the atmosphere.
Who's going to pay for it? At 400ppm, you need a million cubic feet of air to go through your system to get 400 cubic feet of CO2 out. That has an inherent cost.
Whether the CO2 is pulled from the air or from more concentrated industrial sources, the carbon sequestration industry would need to grow to the size of the fossil fuel industry (in terms of mass moved). But instead of extracting resources and selling them for financial gain, it will be a pure financial loss for an ecological gain. Under capitalism it's as impossible as water flowing uphill.
I dream about that but don’t expect it in any foreseeable future. Neither do I believe in a worldwide coordinated economic action when the goal is not money itself but common good.
That would be more reasonable. Carbon offsets turned out to be not reliable because companies are gaming the system and an international way of making sure this does not happen seems unrealistic.
But I personally expect things to just get worse and worse in the next few decades.
Capitalism will not slow down and climate change effects will increase, driving migration into rich countries, causing societal uproar and reduced quality of life for everybody.
Other countries are implementing carbon taxes on their imports from countries that don’t tax carbon so companies will end up paying it indirectly on import taxes if their own government doesn’t levy it.
> it will be a pure financial loss for an ecological gain
Not true, under the current EU emissions trading scheme you can actually earn money by selling the certificates for the CO2 you remove. If you check the price of it you can see that well defined markets can actually get the power of capitalism to work in your favour, with the price jumping from $30 to $90 within last year.
Because I will have already read it and we don't want to have the same discussions in every thread. To quote dang, it makes comments uninteresting and raises the signal to noise ratio.
I have slides? It's quite interesting because the first hypothesis "isothermal atmosphere at the same temperature as the ground" show exactly hw climate change doesn't work.
I read somewhere that sulfur emissions from global shipping have been making the part of the world where such shipping is most active (i.e. around Europe, North America and China) cooler than it otherwise would be. But now we're using low-sulfur fuels, so things might rapidly get worse in these latitudes.
Here is how the earth 'greenhouse effect' really works: https://m.youtube.com/watch?v=oqu5DjzOBF8&pp=ygUlZ3JlZW5ob3V...
