Time for the Obvious solution to global warming
1. Gather the world's top earth scientists
2. Work out where is the low hanging fruit for reducing greenhouse emissions
3. UN (this September) require each country to tip in one percent of GDP per year to adopting those measures til the problem is fixed
4. Levy can be discounted where nations show exceptional improvements in own reductions
5. Get on with it! If we leave it another year, we will be leaving it all too late!
