G8 set new global warming targets to postpone decisions, actions

"Leaders of the G8 leading industrial countries have agreed to try to limit global warming to just 2C (3.6F) above pre-industrial levels by 2050." From BBC. What irks the cynic in me is that no roadmap on how to get there has been agreed. Today’s leaders know well that they will not be in power then, nor their protégés thus could sit on it and leave the task on how to make it happen to future generations. In the meantime, it’s business as usual.
