Ian, thanks for filing under gloom!
Glad to bring a welcome dose of gloom, despondency and despair!
Maybe we should also bring 'Global Warming' Flooding and 'Peak Food' into the mix to cheer everyone up a bit!
O London, see
Swelling with naval pride, the pride of thee!
Wide, deep, unsullied Thames, meandering glides,
and bears thy wealth on mild majestic tides.
