Exegesis of Pope Francis’s encyclical call for action on climate change

The Guardian, 22 June 2015:

It is impossible not to welcome Pope Francis’s concern for the future of our planet, but he is only looking at one aspect of the problem (Francis to target climate change deniers in encyclical before visit to US, 16 June). Emissions of CO2 are a function of carbon emissions per capita and world population. It is illogical to concentrate on the carbon footprint of individuals while ignoring population growth, an issue where the Catholic church could make a real difference. The pope will lack credibility until he acknowledges that contraception is a vital component in the fight against climate change.
