Costa Del Slough

'Costa Del Slough'
The Costa Del Sol is a strip of coast in southern Spain well known for its holiday resorts. The name means the 'Sunny Coast'. Slough is a town in Berkshire of just over 100,000 people on the north bank of the River Thames. It was perhaps most famously name-checked in Sir John Betjemen's 1937 poem of the same name. It starts:

Come friendly bombs and fall on Slough!
It isn't fit for humans now,
There isn't grass to graze a cow.
Swarm over, Death!

...and doesn't get any more complimentary! It was prompted by the rapid industrialisation of the town in anticipation of war with Germany. Betjemen reputedly regretted his harshness in light of the war.

'The hole in the ozone layer'
Martin Holroyd pointed out on Facebook that the hole in the ozone layer does not cause global warming. The ozone is a greenhouse gas and thus a contributory factor to global warming; the hole actually reduces global warming by allowing more heat out. However, the ozone layer does stop harmful ultraviolet radiation from reaching the Earth's surface, which is why a hole is such a problem.

'melanoma'
A melanoma is a skin cancer, normally associated with excessive exposure to the sun. Not something England is supposed to be famed for.
