We're saved! WWF Canada mobilizes "a crack corps of concerned grandmothers" during the Canadian winter to urge people to make it colder inside their houses in an effort to prevent the weather outside their houses from becoming too warm in 2050

National Sweater Day mobilizes grannies against climate change

A [smoking?] crack corps of concerned grandmothers is at the centre of a nationwide campaign to raise awareness of the fight against climate change.

Now in its third year, National Sweater Day is an annual effort organized by World Wildlife Fund Canada (WWF) and sponsored by Loblaws that asks Canadians to turn down their thermostats by two degrees Celsius for a day and wear a sweater instead. The 2013 event takes place this Thursday.

One of the campaign’s key tools is a “granny call centre” staffed by grandmothers who will call people by request and remind them to turn down the heat and put on a sweater.
