The percentage of the greenhouse gas CO2 in the atmosphere has increased radically during the last 100 years. This development is about to create global climate changes. Storing CO2 in the subsurface can give an important contribution to reduce the emission of CO2 into the atmosphere and therefore contribute to a solution of the climate problems. There is a technological race taking place to develop the needed technology and methods for the time being in the following areas:

- CO2 must be trapped and cleaned from exhaust gasses effectively and economically
- Suitable storage sites must be located/discovered and characterised
- Safe techniques must be developed for the injection of the CO2 into the target reservoir
- Methodsv must be developed  to monitor the behavior of CO2 in the reservoir and subsurface

The remains of Leonardo da Vinci are to be exhumed by a group of scientists who plan to reconstruct his face to discover whether his famed masterpiece, the Mona Lisa, is a self-portrait in disguise.  A team of art historians and scientists from Italy's National Committee for Cultural Heritage, has requested that his tomb at Amboise Castle in the Loire valley be opened. Anthropologist Giorgio Gruppioni, hopes the project will throw new light

on the Renaissance painter's most celebrated portrait. 'If we manage to find his skull, we could rebuild Leonardo's face and compare it with the Mona Lisa' he said. Reference: mailonline.
