The solution to the climate change problem can be reached incrementally, I say. The climate change solution is a structure at the summit of a Mayan pyramid that can be ascended from different sides, a step or a few at a time, on each side. REDD-plus is one such expanse of steps: counter-deforestation, reforestation, agriforesty, improving the lives of native peoples around and in forest carbon sinks. Technology transfer is another stair. Imagine what would have been the greenhouse gas reduction accrued since the time of Edison and Tesla if an advanced society had provided the now-developed countries detailed plans for solar panels and wind turbines, and startup grants thereto. Or if Henry Ford had been handed the plans and necessary technical assistance to manufacture Toyota Priuses. The Green Climate Fund (8,10) outlined in the Copenhagen Accord last year is another set of surmountable stone steps pointing to the pyramid’s pinnacle. The CGCF calls for $100 billion climate aid annually by 2020, for adaptation to the least-developed countries, and mitigation all around the developing world. It calls for substantial aid in the meantime too, $30 billion annually through 2012. These are increments that can be accomplished to a very meaningful extent at COP 16. I’ve given three examples, a Mayan pyramid has four sides, but there are many sides of the climate change solution that can be incrementalized and ascended in Cancun, a step or few or several at a time.
