Beyond CO2: Other Greenhouse Gases Intensify Global Warming
Methane, nitrous oxide, and fluorinated gases reach record levels, exacerbating climate change.
- The World Meteorological Organization reports that atmospheric concentrations of methane, nitrous oxide, and fluorinated gases hit new highs in 2023.
- Methane, primarily from agriculture and fossil fuels, has a warming power over 80 times greater than CO2 over 20 years but dissipates faster.
- Nitrous oxide, largely emitted by agricultural practices, is nearly 300 times more potent than CO2 and has increased by 30% in human-induced emissions over four decades.
- Fluorinated gases, used in refrigeration and electrical equipment, have extremely high warming potential, with SF6 being 24,000 times more potent than CO2.
- Efforts to mitigate these gases include reducing methane leaks and more efficient fertilizer use, alongside international agreements to phase out harmful fluorinated gases.
