Global concentrations of carbon dioxide, methane and nitrous oxide climbed to unseen levels in 2023, underlining climate crisis
The levels of the three most important heat-trapping gases in the atmosphere reached new record highs again last year, US scientists have confirmed, underlining the escalating challenge posed by the climate crisis.
The global concentration of carbon dioxide, the most important and prevalent of the greenhouse gases emitted by human activity, rose to an average of 419 parts per million in the atmosphere in 2023 while methane, a powerful if shorter-lasting greenhouse gas, rose to an average of 1922 parts per billion. Levels of nitrous oxide, the third most significant human-caused warming emission, climbed slightly to 336 parts per billion.
The increases do not quite match the record jumps seen in recent years, according to the National Oceanic and Atmospheric Administration (Noaa), but still represent a major change in the composition of the atmosphere even from just a decade ago.
It was a mistake to try and use natural gas as the “bridge fuel” in the energy transition. Sure, natural gas has half the carbon emissions of coal, but it releases methane. Plus, less coal burning means fewer sun reflecting aerosols in the atmosphere. That wouldn’t be a bad thing if we weren’t also pumping heating trapping gases into the atmosphere, but that’s exactly what we’re doing. Instead of replacing our coal power plants with natural gas plants, we should have replaced them with nuclear power plants.

It was an obvious swindle by the fossil fuel industry that nobody but wishful-thinking neoliberals ever fell for in the first place.
The cover image appears to show some interesting dispay technology but no, it’s just an LED display with graphics that pretend it’s mechanical.
Articles need to stop referring to methane as “shorter lasting.” It’s 28 times more effective than carbon dioxide as a greenhouse gas. After a decade it breaks down into carbon dioxide and water, continuing to contribute to the problem.
Friendly reminder: If you aren’t fighting conservatism, you aren’t fighting climate change.
