Getting near net zero increase would be sufficient to avoid an extinction event. > pulls the conversation away from real solutions Do you have a real solution? If not, why badmouth something constructive just because it is not constructive enough? If yes, why don't you post it?

> Getting near net zero increase would be sufficient to avoid an extinction event. --- start quote [1] --- This is the largest, dirtiest coal mine in Europe. It's responsible for 100 Million Tons of CO2 emissions per year. That's 3168 kg of CO2 per second. --- end quote --- I will be flying to Barcelona from Stockholm in June. Some sites show me the three-hour flight will cost 616kg of CO2. Is it per person? I don't know. Let's assume per person (even though I'm pretty sure it's for the entire flight). In that same time that mine will have released 60×60×3.5×3168 = almost 40 million kg of CO2. Enough for every single person on that flight to take over 200 such flights to be anywhere on the same level of CO2 emmissions.

  You're also using the coal mine, just not directly. This is like justifying your personal waste based on the fact that a neighborhood of 10,000 people collectively wastes 10,000 times as much, and you also live in that neighborhood.

    So the biggest impact would be cutting dependence on coal rather than a few hundred people (or even a few thousand people) giving up on air travel.

  > Some sites show me the three-hour flight will cost 616kg of CO2. Is it per person? I don't know. Let's assume per person (even though I'm pretty sure it's for the entire flight). It is per person, going by plane takes roughly as much as going by car if it is over land. Stockholm to Barcelona is according to Google 2788 km. Typical car takes 1.2 litre per 10km, so the whole trip would be around 300 litres of petrol. 1 litre of petrol is around 2.4 kg CO2, so over 700 kg CO2 for the entire trip.
