Travel: A Thanksgiving Walk Through The Old ‘City Of London’ (Video)
Date filmed: Thursday – November 26, 2020
The City of London is a city, ceremonial county and local government district that contains the historic centre and the primary central business district (CBD) of London. It constituted most of London from its settlement by the Romans in the 1st century AD to the Middle Ages, but the modern city named London has since grown far beyond the formal City of London borders.[4][5] The City is now only a tiny part of the metropolis of London, though it remains a notable part of central London. Administratively, it forms one of the 33 local authority districts of London; however, the City of London is not a London borough, a status reserved for the other 32 districts (including London’s only other city, the City of Westminster). It is also a separate ceremonial county, being an enclave surrounded by Greater London, and is the smallest county in the United Kingdom.
The City of London is widely referred to simply as the City (differentiated from the phrase “the city of London” by capitalising City) and is also colloquially known as the Square Mile, as it is 1.12 sq mi (716.80 acres; 2.90 km2)[6] in area. Both of these terms are also often used as metonyms for the United Kingdom’s trading and financial services industries, which continue a notable history of being largely based in the City.[7] The name London is now ordinarily used for a far wider area than just the City. London most often denotes the sprawling London metropolis, or the 32 London boroughs, in addition to the City of London itself. This wider usage of London is documented as far back as 1888, when the County of London was created.[5]

Science Podcast: Covid-19 In Schools, Why Leaves Die And Fall From Trees
Many schools closed in the spring, during the first wave of the coronavirus pandemic. Many opened in the fall. Staff Writer Jennifer Couzin-Frankel joins host Sarah Crespi to talk about what was learned in spring about how coronavirus spreads in schools that might help keep children safe as cases surge once again.
Also this week: What makes leaves fall off deciduous trees when they do—is it the short, cold nights? Or is the timing of so-called “leaf senescence” linked to when spring happens? Sarah talked to Constantin Zohner, a lead scientist at the Institute of Integrative Biology at ETH Zurich, about his tree leaf timing study. Sarah also spoke with commentary author Christy Rollinson, a forest ecologist at the Morton Arboretum, about how important these trees and the timing of their leaf drop is for climate change. In the books segment, host Kiki Sanford talks with Ruth DeFries about her book, What Would Nature Do? A Guide for Our Uncertain Times.
