Climate Change and Policy

Some science

What we know:

1. Accumulation of $CO_2$ and other so called greenhouse gases (GHG) reduce the earth's ability to reflect energy outwards
2. High levels of GHG concentrations in atmosphere

Some science, continued

What we don't know:

1. Full carbon budget
   • All GHG inputs
   • Full functioning of GHG sinks (we know about 75%)
2. How GHG output from human choices will change in future

Predicted Outcomes

1. Our best estimate is that warming will continue and accelerate into the next century.
2. A number of estimated side effects
   • Sea Level Rise
   • Migration of Tropical Disease
   • Desertification
   • Increase in strength and severity of storms
