We're all April Fools - what with Carbon Dioxide levels at 400 PPM for the month.

Scientists expected the 400 ppm mark to be surpassed at an earlier date this year — and, indeed, that point came a full two months earlier than last year — and for this year to see the first monthly carbon dioxide average above 400 ppm.

Must be the lack of oxygen going into our heads.
