In addition any framework that does not include large and fast-growing economies China India Brazil and Russia would be very costly and politically unwise. This chapter has presented several financial and technological strategies to handle the mitigation of global warming. Whichever methods are used will ultimately depend on the region available technology available finances and political policy. What is critical is that action be taken immediately to fight climate change in order to lower the negative consequences of sea-level rise flooding drought disease and other disasters. The International Political Arena Because global warming is a global problem it will take a global solution.
