A show of numbers for Earth Hour

Earth Hour, on Saturday 27 March, is the next chance to demonstrate mass international dedication to achieving social and political change for the good of the planet.

Have we been shouted down by the climate skeptics? Do we too doubt the overwhelming weight of scientific evidence for anthropogenic warming?

No, we haven't and no, we don't.

We know what the right thing to do is. We know what action needs to be taken. We know its not happening fast enough, or loud enough, or high enough.

When a billion other voices join in the call for continued action to avert global disaster, by switching off lights and rallying with their communities on 27 March this year, where will you be?
