New Study: ‘The Positive Externalities of Carbon Dioxide’: ‘Estimating the Monetary Benefits of Rising Atmospheric CO2 Concentrations on Global Food Production’
'The results indicate that the annual total monetary value of this benefit grew from about $20 billion in 1961 to over $160 billion by 2011, amounting to a total sum of $3.5 trillion over the 50-year period 1961-2011. Projecting the monetary value of this positive externality forward in time reveals it will likely bestow an additional $11.6 trillion on crop production between now and 2050'
