Cleary Gardens is on a WWII bomb site, and the exposed levels follow London's history from Roman times to the present. With a wide variety of trees, plans and shrubs it's a haven for nature, you can listen to the sounds here , and examine more of London's nature here (try clicking the "browse" feature).
Much as I believe current climate change is being influenced by man's activity, we shouldn't forget that climate change is a natural, cyclical thing. Vines used to grow here in the middle ages, the rebuilding of the garden was sponsored by Loire Valley Wines. Mmmmmmm a nice a Vouvray will do nicely, thank you, or maybe St Nicolas de Borgueil.
See where on the London Daily Photo Map.
