March 23 2025 - On The Very Edge Of 430 Parts Per Million [View all]
Last edited Tue Mar 25, 2025, 03:13 PM - Edit history (1)
So as of yesterday, we were at 429.64 ppm per NOAA/GML. We could hit 430 tomorrow (that is, today, with confirmation of the March 24th numbers), or it could be next week, since daily readings bounce around a fair amount.
What is certain is that we'll breach 430 soon, though only temporarily through early June. That too will change. What is also certain is that by late March 2027, 430 will be permanently and irrevocably in the rearview.
