Climate science development, fossil fuel companies response

Tyndall’s apparatus used in his experiments on absorption properties of different gases, where he concluded that water vapor and carbon dioxide are most responsible for trapping heat in the atmosphere and any change in the levels of these gases “must produce a change of climate.” (Image source from “The Discovery of the Greenhouse Effect” by Dr Steve Easterbrook, March 2017 and adapted from Tyndall, 1861)

  by John Colin Yokingco We are given a deadline: 2030 – 12 years from now. According to the Intergovernmental Panel on Climate Change (IPCC) Special Report 15, we have 12 years to drastically reduce our emissions or else it will be too late to slow down global warming to a rate that can return our climate to pre-industrial temperatures. If emissions are not reduced, a climate out of balance is expected, resulting in increased severity in weather events such as typhoons and droughts, as well as sea level rise that puts at risk small island states and coastal areas. Millions of people are already experiencing the impacts of climate change, and if no action is taken, these impacts are bound to worsen and affect even more people. What the IPCC said in their special report, however, is not something that we have heard for the first time. This is not new information. Early observations As early as the 19th century, Irish physicist John Tyndall (1820-1893) observed and concluded that because of the nature of certain gases to trap infrared radiation, changing their concentration in the atmosphere could lead to a changing climate. His observations were affirmed by Swedish scientist Svante

Knowledge on the catastrophic effects of increased carbon dioxide (CO2) levels in the atmosphere has been around as early as the 1800s, and the top CO2 emitters were even warned by their own scientists of the possible effects of these emissions to the climate. However, along with the continuing research, warnings, and global initiatives to reduce the onset of global warming, there were also consistent campaigns from fossil fuel companies to spread doubt and denial on the role of man-made greenhouse gases to climate change, a timeline of which is illustrated below: (This infographic depicts a selection of events and is not meant to be a comprehensive documentation, and would benefit from a regular updating. The infographic was developed by staff of Ecojesuit and Environmental Science for Social Change: John Colin Yokingco for the text and Maricel De Jesus for the visualization.)

An ecologist’s reflections on the formation of the IAJU

by Nancy Tuchman I returned from an extraordinary meeting of the presidents of the 211 worldwide Jesuit universities that has made an impact on me from the perspective of an ecologist who is greatly concerned about the state of our planet. The conference took place at Universidad Deusto in Bilbao, Spain near the birthplace of...

A personal response to Laudato Si’

by Edmond Grace SJ Laudato Si’ marked a shift of perspective for me with regard to the everyday commitments called for by the ecological crisis in areas such as water usage, transport, food waste. I saw these commitments as a variation on Saint Augustine’s prayer for chastity: ‘Make me green, Lord, but not yet.’ I...
