I think the climates of many regions of the earth is changing. Bush fires, droughts & floods all appear to be becoming more frequent & severe.

This seems more likely to be caused by poor land management and/or solar activity than by CO2 levels though. Water cycles & soil coverage have a dramatic impact on rainfall and temperatures in a region. Higher CO2 levels ironically probably help repair the damage/imbalances.

My issue is with the assumption that we adequately understand the problems & have a solution. It's the hubris of central planning that really pisses me off.
