No Longer Number One

Chicago is now Number Two (pun intended):

• A new town is claiming the unsavory title of “rattiest city,” a title long-held by Chicago, according to a study released Tuesday by Orkin pest control company.

  For the last 10 years, Chicago has held the unwanted title of “America’s rattiest city,” a label the city has been trying hard to shed. The city was granted its wish when Los Angeles took over the No. 1 spot.

  [...] The shift was likely influenced by weather patterns, urban infrastructure and human behavior, the pest control company said.

  However, Chicago still holds the No. 2 spot — with New York City in third place and San Francisco in fourth.

"weather patterns"

It's always "global warming."
