Geoengineering - the deliberate, large-scale manipulation of the earth's climate to offset global warming - is a nightmare fix for climate change.

Sometimes we look for those thunderous things to happen in our life for our lives to change or go in the other direction. We seek the miracle. We seek the parting of the seas, the moving of the mountains. But no, it's a quiet thing. At least for me it was.

If you are interested enough in the climate crisis to read this post, you probably know that 2 degrees Centigrade of warming (or 3.6 degrees Fahrenheit) is the widely acknowledged threshold for dangerous climate change.

Climate change is a global issue - from the point of view of the Earth's climate, a molecule of CO2 emitted in Bejing is the same as a molecule emitted in Sydney.

What's certain is that a totalitarian enclave like Cuba's can't continue to exist, so change will definitely come there, eventually.

Every day I'm thinking about change.

Ever since the collapse of cap and trade legislation and the realization that President Obama is unlikely to ever utter the words 'climate change' in public again, much less use the bully pulpit to prepare the nation for the catastrophic risks of inaction, the movement has been in a funk.

I mean, I think we're put here on earth to make your own destiny, to begin with. I don't think there's anything you can do this way or that way to change anything.

Maybe more climate activists will think about the climate change not as an international problem to be resolved in an air-conditioned meeting hall, but as a guerilla war to be fought in the streets.

I don't think the Palestinian people or Afghan children or some other things I'm concerned about are at the top of other people's agendas - not right now, when America is going through such a recession and people are suffering across the board financially. But I think all that will change.
