"In the late 1700s, the air contained about 280 parts per million (ppm) of CO2. We are now up to 420 ppm, an increase of about 50%..."

Yikes! We're like that cartoon character that was speeding off the top of the cliff and now he's hanging suspended in mid air just before dropping to his death.

Fifty percent increase in three hundred years seems like a lot; particularly considering that its all likely to hang around for a thousand years or more. I don't think I can wait that long.

Bit sad that climate is rarely discussed on HN. A mountain of studies indicates our current civilization will completely collapse within this century due to climate.

It is an "industry" ready to be disrupted.

It's rarely discussed because it's impossible to have an open-minded discussion about climate change.
