Earth ours

“Earth Hour was first unveiled by an Australian ad agency in 2007, when global atmospheric concentrations of carbon dioxide had reached 385 parts per million, their highest level in some four million years. Since then, CO2 levels have broken through the symbolic 400ppm barrier and continue to rise sharply.
The impact has been stark. Eight of the 10 hottest years ever recorded have all occurred since 2007. Last year smashed all previous records, pushing Earth systems into what the World Meteorological Organisation this week called ‘truly uncharted territory’.
If homo sapiens really has the wit and ambition to survive this century, from here on every hour has to be Earth Hour.”

Blogging on battery power seems a decent analogy for stealing resources from our future selves.

Can you display darkness?
If you can switch off the aurora you can pretty much do what you like.
