So much for the cheapest alternative. > DJ, it's a bit off topic here although it's germane to the world's economic system and disruption. However, the single biggest cause of global warming is the sun's output. The next biggest variable is cloud and snow cover. Global warming due to people digging and burning hydrocarbons is a trivial problem if it is in fact happening, which I doubt. Recycling is good and recycling carbon is very very good. Recycling carbon is what life does. Having more CO2 causes much greater plant growth [as you know]. That's why farmers burn gas to heat and enrich their glasshouses with CO2 so the plants can eat and grow. If the atmosphere does warm up a bit, that will be a problem in very few places and the cost of disruption in those places would be offset by the gains from plant productivity increase around the world due to increased CO2 and climate improvement in chilly places like New Zealand. People should get awards for enhancing the food supply of plants when they burn hydrocarbons. But wait, there's more. The normal state of the world in recent eons is ice age. If you think global warming is bad, you should try living under a 4km thick ice sheet over northern Europe. That really makes it tough to grow food. Ensuring the earth stays warm will stop any ice age encroachment - ice ages are runaway events because as the ice cover increases, reflection increases and the earth flips rapidly [in only a few years] to an ice age as each winter's snow cover extends further and further towards the equator. As the earth cools, there is more cloud formed too which reflects more heat and the water from the clouds falls out as snow. It's a fascinating energy balance. Mqurice
