Costs of global warming: 5 trillion USD

I read yesterday on The Independent, quoting Dr. Keywan Riahi that the costs of delaying in actions against global warming is already estimated as 5,000,000,000,000 USD, which is 25% higher that the previous prognosis. As it is further delayed, we should expect more costs. However, it seems the politicians are ready to pay for the natural disasters, but not ready to pay anything to stop it.

In another news, we see that 30-50% of the foods are wasted in different steps of its processing from harvesting the agricultural products until its end usage. Its prognosis point to about 2,000,000,000 tons materials.

If we consider just these two news, we can roughly calculate the potential of producing fuels (such as biogas) for about 200 billion liters of gasoline or kerosene from this food materials that is wasted. This amount is equal to about 15% of the global gasoline market. This simple calculation shows the huge potential of our current resources for avoiding global warming. However, we have to wake up!
