My husband heard about this at work today.
An organisation called The Alliance for the Planet called for everybody to create 5 minutes of electrical rest for the planet at the same time throughout the world. The purpose was to show political leaders that global warming is an issue that needs to come first and foremost in political debate. February 1st was chosen as the day when a new UN report on global climate change was brought out in Paris. The times were 1.55-2.00pm in New York, 6.55-7.00pm in UK etc.
6.55pm happens to be just about the time we finish eating so we made sure that everything in the house was switched off (actually we realised afterwards that we forgot the fridge/freezer) and sat at the table by candlelight for five minutes. I have no idea how many people took part or whether anyone will take any notice but it was a peaceful five minutes.
