With the Tories' climate credentials in disarray, it seems like a good moment to recall this iconic frontpage of the Times from 33 years ago...

Yesterday, Antarctic sea ice extent hit a new record statistical low of -6.65σ below the 1991-2020 mean. About a 1-in-70B chance w/o climate change.

@stepsupportcam This is a marvellous result which I enjoy teaching to my Further Maths pupils. However, there is a typo in your Hint! It is correct in the marvellous STEP database https://t.co/sQFEm2wAFA
But both start with a bigger mistake:
1 = 0 not 1 = 0 + 1
