In occasione dei grandi convegni internazionali, in cui si devono prendere decisioni in base ai dati e informazioni, è d’uso assistere a incontri tra addetti ai lavori, workshop, seminari per mettere a fuoco qualche aspetto e per fare il punto della situazione.
Quali sono i punti salienti di questo studio aggiornato sul cambiamento climatico?
Per rendere stabile il sistema climatico del pianeta, riportandolo in condizioni di variabilità naturale (con azioni “decarbonizzanti” e riducendo a “zero” le emissioni di CO2 e degli altri gas serra), le nazioni industrializzate dovrebbero raggiungere entro il 2050 una media annuale di emissioni inferiori a una tonnellata di CO2 pro capite e, quindi, ridurre dell′80% al 95% le emissioni pro-capite rispetto all’anno 2000.
Di sicuro si parlerà anche del Climategate conseguente al trafugamento delle corrispondenze e-mail dei ricercatori dello staff di Michael Mann (attualmente direttore del Centro di Studio Climatologico e Geologico (Earth System Science Center), a capo dello staff autore del famoso grafico "Hockey Stick" che descrive le temperature nel passato), che è stato accusato da molti di essere errato se non - addirittura - "manipolato".
Quanto sta emergendo dal “Climategate” costituirà tema di discussione su metodi, termini e criteri inerenti la comunicazione scientifica in materia climatica e ambientale, e anche a come evitare di avvelenare l’informazione sui media con interventi qualunquisti per fini di interesse politico-economico.
Informiamo che il vice-presidente di EnergoClub, Sara Capuzzo, sarà presente alla Conferenza di Copenhagen come osservatore accreditato.
