Did I miss the part of the article stating what percentage of all effects this would have? Like if it moves the needle 0.000001% is it worth the effort? Not to play whatabouttism, but the top 8 countries after China (US through Germany) together emit about the same amount of CO2 as China alone. Not saying we shouldn't improve where we can, as the sum of many small efforts helps the whole.

> How, then, do contrails stack up in terms of total warming? They contribute roughly 2% to the world’s effective radiative forcing; tackling them would reduce that by a similar amount.

Thanks, that is quite signficant

I'm wondering if I missed this too. The percentage of the sky covered in contrails must be... absolutely minimal?

If it was even 1% we'd surely be up in arms about how awful it looked.
