The Paris Agreement is an international treaty that aims to limit global warming to well below 2 degrees Celsius above pre-industrial levels, by reducing greenhouse gas emissions.

Adaptation refers to adjustments in human and natural systems to cope with the impacts of climate change.

Methane has a much higher warming potential than carbon dioxide or nitrous oxide, even though it is present in lower concentrations in the atmosphere.

The main cause of the hole in the ozone layer is the release of chlorofluorocarbons (CFCs) into the atmosphere, which break down ozone molecules.

The main cause of sea level rise is the thermal expansion of seawater due to global warming.

Livestock is the largest source of methane emissions, accounting for approximately 16% of global methane emissions.
