Quanto conosciamo dell'oceano, grande protagonista dell'evoluzione della vita e delle attuali caratteristiche climatiche del nostro pianeta? Pochi sanno della sua reattività chimica, della sua alcalinità, dei sottili meccanismi che stanno alla base dei tanti equilibri e disequilibri chimici al suo interno. Il libro cerca di gettare luce sulle basi chimiche di questi fenomeni e sulla loro risoluzione matematica attraverso algoritmi relativamente semplici, comprensibili e spiegati in modo elementare. Sulla base di questo, vengono discusse alcune simulazioni, ma non solo, il lettore è messo in grado di effettuarne altre, sulla base dei programmi allegati. Si potranno così avere risposte scientifiche sui vari quesiti climatologici, come l'assorbimento e l'emissione di CO2, la formazione di carbonato di calcio negli oceani e altri aspetti di interesse e di attualità.
This publication draws upon the fields of science, economics and business strategy to chart the future of humankind's relationship to the ocean. A healthy ocean provides the basis for a prosperous world, and oceans have been largely ignored as a driver of human well-being until now. Ocean health has been in a serious state of decline for the past 100 years from a range of pressures including human population growth, energy consumption and use of natural resources. Humanity will exceed the resources and environmental conditions necessary to exist, within the next century if nothing changes. Solutions to these challenges lie not only in traditional resource conservation management, but in new fields of technology, governance and innovation.
