One thing about climate change: it disproves the capitalist ideology that poor people's suffering is their own fault.
Billionaires emit as much in a day as the world's 4 billion poorest emit in a yr, yet those 4 billion humans suffer most from climate impacts.
This is inequality, and it is evil.

More electrical then diesel cars in Norway, good example of society adaptation, countries like mine (#Switzerland) could learn from more agile countries how to become really INDEPENDENT (not importing fossil and better using free resources ) and NEUTRAL (not financing war by buying oil and gas).
Diesel and petrol cars are disappearing rapidly from Norwegian roads. In just a decade, electric vehicles have grown to become the largest drivetrain/fuel type in the Norwegian passenger car fleet.
