00:00Earth's atmospheric CO2 reached a record 426.8 parts per million in 2025.
00:07Now, scientists warn that a powerful El Nino could push concentrations even higher.
00:12The World Meteorological Organization says carbon dioxide, methane, and nitrous oxide
00:17all reached record levels.
00:19CO2 alone rose by 2.8 parts per million in one year.
00:23These figures measure gases accumulating in the atmosphere,
00:26not just emissions released during the year.
00:29However, here's why El Nino matters.
00:31This natural climate pattern can bring hotter, drier conditions to some regions,
00:35making it harder for land ecosystems to absorb carbon.
00:38Meanwhile, a little-known gas called sulfur hexafluoride,
00:42used in electrical equipment, has an extraordinary warming effect.
00:46Over a 100-year period, its warming potential is about 2,4300 times that of CO2 per equal mass.
00:53The warning is clear.
00:55Greenhouse gases keep building up, and their effects can last for generations.
00:59Scientists expect concentrations to rise further in 2026,
01:04but the full-year outcome remains to be measured.
