A scientific consideration of climate (I) Crucial experiments like the famous experiment of Michelson e Morley are not possible in climate science How is it possible a scientific investigation of climate ?
A scientific consideration of climate (II) We can male experiments if we represent the climate system via a set of mathematical relations: the equation of climate. The equation of climate are very difficult, but they can be solved by numerical methods. We can then treat very complex mathematical equations, paying the price of a enormous number of elementary operations.
The next generation of numerical models will be like new, more powerful, telescopes or particle accelerators and they will allow us to look further into the working of the Earth climate more accurately, extensively and reliably.

CIRCE Climate Change and Impact ResearCh: the Mediterranean Environment An FP6 Project of the European Union Chair: Antonio Navarra and Laurence Tubiana
The project will investigate how global and Mediterranean climates interact, how the radiative properties of the atmosphere and the radiative fluxes vary, the interaction between cloudiness and aerosol, the modifications in the water cycle. The economic and social consequences of climate change shall be evaluated by analyzing direct impacts on migration, tourism and energy markets together with indirect impacts on the economic system. CIRCE will moreover investigate the consequences on agriculture, forests and ecosystems, human health and air quality. The variability of extreme events in the future scenario and their impacts will be assessed. The integrated results discussed by the project CIRCE will be presented in the first Regional Assessment of Climate Change in the Mediterranean area.

What can we do ? Mitigation: remove the causes of climate change, i.e. emissions Adaptation: prepare for the coming climate change

Elements for Post-Kyoto Regime Effective – Capable of realizing significant emission reduction Empowering – Allowing emerging countries to continue their development path Fair – Recognizing the historical responsibility of mature economies Shared – A large societal consensus is needed to implement effectively the policies
General Social Survey USA (I) • 86% - Satisfied of their job • 76% - Satisfied of their income • 62% - Expect their position to improve within the next three years • 65% - Over all satisfied of their lives
General Social Survey USA (II) • 25% - Think the country is not “on the right track” • 80% - Think the Congress has accomplished nothing • 60% - Expect next generation will be worst off
”Happiness Gap” US citizens ( probably typical of other countries) are happy with their lives, but they feel the threat of outside forces beyond their control (climate change, terrorism, credit crisis) and they are doubt of the government capability to handle them effectively There is a private-public happiness gap
Policy ? In this situation the demand on policymakers is to devise a policy to tackle with determination these large problems, but without touching the sphere of private satisfaction of the individual. Is it possible to define a policy addressing these demands ?
