Bloggers consider the disappointing results from the G8 summit:

• Kate Sheppard at Gristmill explains why the G8 climate agreement is not so great (especially when considered in light of goals set in 1992).
• Richard Littlemore at DeSmogBlog lays the blame for the G8’s climate standstill on three men.
• Angelique van Engelen at Triple Pundit takes on the issue of China’s emissions (one of the summit sticking points), and suggests a new method for emissions accounting.
• Jill Sheffield at RH Reality Check reminds us that the G8 meeting was also addressing maternal and child health issues, and gives the summit a mixed review on that score.
