climateWhat is Carbon Dioxide (CO2)?
Carbon dioxide is the most important long-lived greenhouse gas driving climate change. Concentrations are measured at Mauna Loa observatory and other stations worldwide. CO2 persists in the atmosphere for centuries, meaning today’s emissions will affect climate for generations. Southeast Asia contributes to CO2 through peat fires, deforestation, and rapidly growing energy consumption, while being disproportionately affected by the consequences.
