A Day for Planetary Justice
PRINCETON – What we are doing to our planet, to our children and grandchildren, and to the poor, by our heedless production of greenhouse gases, is one of the great moral wrongs of our age. On October 24, you can stand up against this injustice.
October 24 is 350 Day. The name comes from the number of parts per million of carbon dioxide in the atmosphere that, according to Jim Hansen, perhaps the world’s leading climate scientist, we should not exceed if we are to avoid potentially catastrophic climate change. It is a measure of the seriousness of our problem that CO2 is already at 386 ppm, and is rising by two ppm each year.
The need to cut greenhouse gases has become increasingly clear as predictions of global warming – denounced as “alarmist” when they were first made just a few years ago – have repeatedly turned out to have been too conservative. We are approaching a point of no return, at which feedback loops will kick in and continue to warm the planet, no matter what we do.
