Un modo migliore per contrastare il cambiamento climatico

NEW YORK – Tra tutte le principali regioni del mondo, l’Europa è quella che ha lavorato più duramente per implementare le politiche mirate a contrastare il cambiamento climatico causato dall’uomo. Ciò nonostante, il pilastro dell’approccio europeo, ovvero un sistema di scambio di emissioni per i gas serra, causa del cambiamento climatico, a livello di tutto il continente, è in difficoltà. Ciò sta a indicare che è necessaria una strategia migliore sia per l’Europa che per il resto del mondo.

Le fondamenta della storia del cambiamento climatico generato dall’uomo stanno diventando sempre più chiare al pubblico globale. Diversi gas, tra cui il diossido di carbonio, il metano e il protossido di azoto, riscaldano il pianeta lasciando una concentrazione sempre maggiore di questi gas nell’atmosfera. La crescita dell’economia mondiale è ormai parallela ad un aumento delle emissioni di questi gas che accelerano il passo del cambiamento climatico causato dall’uomo.

Il principale gas serra è il diossido di carbonio. Gran parte delle emissioni di CO2   provengono dalla combustione dei combustibili fossili (carbone, petrolio e gas naturali) per la produzione di energia, il cui consumo globale continua ad aumentare in parallelo alla crescita dell’economia mondiale. Ne risulta che stiamo andando verso dei livelli molto pericolosi di CO2 nell’atmosfera.

  3. Murdoch's Last Stand?

    Rupert Murdoch’s sale of 21st Century Fox’s entertainment assets to Disney for $66 billion may mark the end of the media mogul’s career, which will long be remembered for its corrosive effect on democratic discourse on both sides of the Atlantic. 

    From enabling the rise of Donald Trump to hacking the telephone of a murdered British schoolgirl, Murdoch’s media empire has staked its success on stoking populist rage.

    The Dangerous Delusion of Price Stability

    Since the hyperinflation of the 1970s, which central banks were right to combat by whatever means necessary, maintaining positive but low inflation has become a monetary-policy obsession. But, because the world economy has changed dramatically since then, central bankers have started to miss the monetary-policy forest for the trees.

But ensuring that those changes are positive – helping to fight tumors and mosquito-borne illnesses, for example – will require scientists to apply the utmost caution.
