Show HN: BornAtXCO2 – What CO2 PPM were you born at, how much has it increased

320, ^31%. Horrifying isn't it. Any other core gas we'd all be long dead, along with most other life.

@op, entering 1902, Nov, 15 gives NaN% and bricks the site. (Looks like anything below 1958 or so doesn't have data?)

I wonder if phrasing it as<p>&gt; You were born at 0.0xyz% CO2, It is now 0.0abc% CO2<p>instead of using PPM would be less alarming.

interesting and sobering calculator
