That canna be true, captain

Suppose you have three thousand reporting stations and each one has a ninety-nine year record. How many daily record highs would you expect to see in the 100th year?

3000 * 365 / 100 = 10,950 daily record highs.

How many stations would be expected to record their hottest year ever?

3000 / 100 = 30

In a perfectly stable climate, we would expect thirty stations to record their hottest year ever.

It is called freshman math, not global warming.

The wintry west extends his blast,
And hail and rain does blaw;
Or the stormy north sends driving forth
The blinding sleet and snaw:
While, tumbling brown, the burn comes down,
And roars frae bank to brae;
And bird and beast in covert rest,
And pass the heartless day.
