The encyclical letter Laudato Si is available here on the Vatican website.
More descriptions here, first those that concern:
26. Many of those who possess more resources and economic or political power seem mostly to be concerned with masking the problems or concealing their symptoms, simply making efforts to reduce some of the negative impacts of climate change.
Is it fair to impugn the motives of some? There are a lot of intelligent people in the skeptic camp. But much of Western culture aims at short-term gain, or maintaining profit. Nearly all Western politics has a short memory, narrow vision, and a stunted reach.
However, many of these symptoms indicate that such effects will continue to worsen if we continue with current models of production and consumption. There is an urgent need to develop policies so that, in the next few years, the emission of carbon dioxide and other highly polluting gases can be drastically reduced, for example, substituting for fossil fuels and developing sources of renewable energy. Worldwide there is minimal access to clean and renewable energy. There is still a need to develop adequate storage technologies.
Some countries have made considerable progress, although it is far from constituting a significant proportion. Investments have also been made in means of production and transportation which consume less energy and require fewer raw materials, as well as in methods of construction and renovating buildings which improve their energy efficiency. But these good practices are still far from widespread.
More research is definitely needed. Pope Francis hasn’t addressed this, but resources wasted in military adventurism would be better-used to provide for the future.
