Things I learned this week

I learned that:
• In 1927, the U.S. was worried about possible aggression by Britain, and developed a war plan to invade Canada, if necessary. The secret plan was declassified in 1974.

• The amount of water the atmosphere can hold increases by about 8% per degree Celsius temperature rise (the Clausius-Clapeyron relation). Consider this in the context of global warming. Perhaps we Ontarians will be living in a rainforest?

• About 13% of the world's population lives less than 10 meters above sea level. Portions of many major cities are actually at sea level, including New York, London, Miami, Boston, Copenhagen, Amsterdam, and Singapore. Sea levels are predicted to rise due to global warming.

• North America's first vertical urban farm is being built on a downtown Vancouver parking lot. Beginning in October, it will deliver leafy green vegetables and herbs to local markets.

• 70% of Facebook and Twitter followers are fake or inactive.

• Nearly four-in-ten Americans surveyed say that marriage is becoming obsolete.
How about that?
