The Paris Agreement on climate change sets a framework for the control of greenhouse gas (GHG) emissions. It has been a catalyst for many efforts related to decarbonisation.
Interestingly, it does not explicitly mention carbon dioxide (CO2) once. Neither does it name methane, nitrous oxide, nor fluorinated hydrocarbons, known as F-Gases, which are all potent greenhouse gases.
Global warming caused by man-made greenhouse gas emissions is causing ecosystems to change. These changes can result in a higher levels of methane emissions. For example, as the tundra in Siberia thaws, trapped methane gas is released to the atmosphere. Human activity has pushed the first domino; the next ones are beginning to topple.
