Greenhouse Gas Levels Set Records In 2025, UN Says

An anonymous reader quotes a report from CBS News: Greenhouse gas concentrations in the atmosphere rose to record highs in 2025, locking in climate impacts that will persist for centuries, the United Nations said on Tuesday. Levels of the three main greenhouse gases -- the climate-warming carbon dioxide, methane and nitrous oxide -- all rose to unprecedented figures in 2025, the U.N.'s weather and climate agency said. The World Meteorological Organization said the rise would lead to more long-term temperature increases for the planet.

The bulletin looks at greenhouse gas concentrations -- the amount of those gases in the atmosphere -- rather than new annual emissions amounts as the world burns more coal, oil and gas. In 2025, carbon dioxide concentrations were at 426.8 parts per million (ppm); methane at 1,948 parts per billion, and nitrous oxide at 339.1 parts per billion. That takes them, respectively, to 153%, 267% and 126% of the pre-industrial levels witnessed before 1750. Of the three major greenhouse gases, CO2 accounts for about 66% of the warming effect on the climate.

Around half of the total CO2 emitted each year remains in the atmosphere; the rest is absorbed by the land and oceans. From 2024 to 2025, the global average concentration of CO2 rose by 2.8 ppm -- smaller than the record surge from 2023 to 2024 of 3.6 ppm. WMO senior scientific officer Oksana Tarasova said this reflected the "recovery of the land carbon sinks and reduced fire carbon emissions in 2025 after the strong 2023/2024 El Nino," the naturally occurring, climate-warming weather phenomenon. "However, a 2.8 ppm annual increase is still a substantial addition of carbon to the atmosphere from fossil fuel burning." It is also above the average growth rate for the past decade of 2.6 ppm -- a figure that stood at 0.8 ppm in the 1960s. "Another year, another new record," said WMO Deputy Secretary-General Ko Barrett. "Greenhouse gases are trapping an unprecedented amount of heat in the atmosphere, providing energy for more extreme weather and associated risks to our economies and societies.

Israel election results live: exit polls point to tie between Netanyahu and Eisenkot blocs

Both blocs would fall short of the 61 seats needed to form a government as support for Palestinian parties surges

It’s just after 6am in Tel Aviv where Israeli’s are waking up to exit polls that show no clear victor in yesterday’s elections, with uncertainty guaranteed at this point.

The polls published by Israel’s major TV networks show Benjamin Netanyahu’s governing bloc tied with the opposition grouping led by Gadi Eisenkot on 51 seats each, short of the 61 seats needed to form a majority coalition government.

Netanyahu took the stage at a post-election rally in Jerusalem just after 3am, telling his supporters official results will show that “Likud is the largest party in Israel”. He told his supporters that the country must “establish a strong, right-wing national government” – adding that a government that relies on the support of Palestinian parties must not be formed.

Eisenkot told cheering supporters in Tel Aviv that the “Israeli public has voted against Netanyahu’s service as Israel’s prime minister … a worthy leader would have accepted the people’s non-confidence and announced today his retirement from politics.” In his speech, he also warned Netanyahu not to “use Israel’s security” for political ends, playing on fears that the prime minister could use this period of uncertainty to launch a new attack on Iran.

The exit polls were released after a last-ditch effort by Netanyahu and several other parties to keep polling stations open beyond their 10pm deadline was rejected by the Central Elections Committee. The prime minister suggested publicly that efforts were being made by the “left and Arabs” to steal the election, a claim rejected by the committee, which said it had seen no evidence of systematic tampering.
