People need to realize that the effects of global warming are at this point unstoppable. No conservation effort and certainly no carbon dioxide removal program could possibly show an effect for decades. At which point the damage will already be done. Money would be much better spent preparing for sea level rise etc than trying to prevent it.
Not to be a downer but the number of people killed by famine, drought, sea level rise, etc will probably be more effective at curbing CO2 output than any policy measures.
