Is it remotely feasible to remove 12 billion tonnes of carbon dioxide from the air? Every year. For decades to come. That's the challenge posed by the latest conclusions of the UN's climate science panel. It says that only by pulling this heat-trapping gas out of the atmosphere can we avoid dangerous climate change. But according to one leading researcher, there's a bit of a hitch: 'We haven't a clue how to do it'.

Can we start calling it Climate Breakdown, Climate Crisis, Climate Disaster, or some term that correctly, accurately emphasizes the negative?

"Climate Change" is pretty weak...like terminology National "Public" Broadcasting would use.

I just checked. If 12 billion tonnes of carbon could be sucked from the air every year, I guess that would be a step in the right direction. But, it would be a pretty small step. Human activity emits about 40 billion metric tons into the atmosphere every year and I am sure that amount is increasing. But at 40, removing 12 would net out at 28 billion. Relative to 40 that might be a "feel good" number. But I don't think "feel good" numbers are going to do us much good unless the feel good number is zero or less. I say that because even if we could net out at '0' emissions for humans, the feedback loops will continue cranking up releasing great quantities of methane and also the melting arctic ice will be reflecting less and less solar radiation.

I kid you not. I used to be an optimist, about 50 years ago. :)

Carbon can be quickly removed from the air by mimicking nature. It has happened in the past. When the population and thus agriculture collapsed after Columbus, the weeds took over the abandoned gardens and fields. The grazers moved in since the apex predator was gone and grasslands and forests took over sucking enough CO2 from the air to drop temps world wide by 1C and creating the Little Ice Age.

The same could be done today quickly by removing subsidies for crops grown on plowed and poisoned land and transferring them to crops and animals grown on untilled land. Even ADM and ConAgra will change with the proper incentives. In the meantime, as individuals we can grow our own, eat organic produce and grass fed and pastured meat, dairy and eggs and accompany meals with biodynamic wine grown in the fire ravaged counties of Napa, Sonoma and Mendocino, a pleasurable and healthy method of eating for your family and the planet.

And we would replace the Arctic sea ice and restore what habitats remain somehow? Remove capitalism from the equation? Remove methane and nitrous oxide how? Simple starters for questions that would easily fill a mighty large book.


Farmers around the world are already facing disaster, with many already giving up. These are the folks who watch the climate like hawks just to make a living.
