3 T.S. Eliot INGV - Istituto Nazionale di Geofisica e Vulcanologia - Italy The Waste Land I. The Burial of the Dead April is the cruelest month, breeding Lilacs out of the dead land, mixing Memory and desire, stirring Dull roots with spring rain. Winter kept us warm, covering Earth in forgetful snow, feeding A little life with dried tubers. Summer surprised us, coming over the Starnbergersee With a shower of rain; we stopped in the colonnade, we went.

9 A scientific consideration of climate (I) INGV - Istituto Nazionale di Geofisica e Vulcanologia - Italy 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?
10 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. INGV - Istituto Nazionale di Geofisica e Vulcanologia - Italy 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.
11 Le Equazioni di Navier-Stokes
12 The next generation of numerical models will be like INGV - Istituto Nazionale di Geofisica e Vulcanologia - Italy 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.

25 CIRCE Climate Change and Impact ResearCh: the Mediterranean Environment An FP6 Project of the European Union INGV - Istituto Nazionale di Geofisica e Vulcanologia - Italy Chair: Antonio Navarra and Laurence Tubiana
26 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.

36 Happiness Gap INGV - Istituto Nazionale di Geofisica e Vulcanologia - Italy 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
37 Policy? INGV - Istituto Nazionale di Geofisica e Vulcanologia - Italy 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?
