Q. Which organization recently released its annual Greenhouse Gas Bulletin?
Answer: World Meteorological Organization
Notes: The World Meteorological Organization (WMO) released its annual Greenhouse Gas Bulletin, first published in 2004. The bulletin analyzes greenhouse gas concentrations from the WMO Global Atmosphere Watch Programme. Global average CO2 reached 420 ppm, methane at 1934 ppb, and nitrous oxide at 336.9 ppb, significantly above pre-industrial levels. Methane and nitrous oxide levels increased, contributing to global warming. Drivers of the rise include high CO2 emissions from fossil fuels, vegetation fires, and reduced carbon absorption. The report urges immediate action to meet Paris Agreement goals and curb rising greenhouse gas levels.
