#2"The observed downward trend amounts to 19 'per meg' per year. This corresponds to losing 19 O2 molecules out of every 1 million O2 molecules in the atmosphere each year."

#3Losing O2 isn't a huge deal as humans - it's the outsized effect of replacing O2 with CO2. O2 is 20% of the air, N2 is 78%.
CO2 lives in that last little bit and, given its miniscule contribution to composition, has a far outsized effect.

That's a 0.0019% decrease, not very significant is it?

It's 0.002%/yr. Mostly just impressed that we can measure this at all.

Not today, but the trend is worrying, especially if the rate increases. What will this look like in 50 years? 1,000?

Gaining CO2 has more of an effect: https://www.news-medical.net/news/20200421/Atmospheric-CO2-l...

50 * 0.0019% = 0.00095 1000 * 0.0019% = 1.9%
Previous commenter said if the loss accelerates. Larger and larger changes each year would be more than worrisome.
