I'm thinking we should get out of the UN entirely, but this would be a start.
From the article:
The UNFCCC Is an Unworkable, Ineffective Approach—Even if Global Warming Is as Problematic as the IPCC Projects
U.N. climate conferences have become increasingly irrelevant, in large part because the approach taken is unworkable. International negotiations have centered on placing the economic burden of addressing climate change on a few dozen developed countries while asking little or nothing from more the 150 developing countries. But the primary source of GHG emissions is increasingly the developing world, most notably from large developing economies such as China and India.
This is an interesting explanation in economic terms, but what this really says is the third world seeks to harm Western democracies. This is what the UN has evolved to and is no longer an organization for solving world problems appropriately.
