One interpretation would be that a change in the rate of natural warming led to a change in the rate of CO2 increase. Warmer oceans can absorb less CO2 for example. The Met Office of course wants to attribute any and all warming to humans, but has no empirical evidence of such claims. It turns a blind eye to the fact that the recent ‘unexplained spike’ in global temperatures has baffled climate scientists, and pretends it has all the answers, stoking alarm about the extra ~3 parts per million of atmospheric molecules of CO2 (world can’t cope etc.)

The UK weather service said Friday that carbon dioxide levels in the atmosphere in 2024 grew at the fastest annual rate on record, exceeding their own projections by some margin, says Phys.org.
The sharp rise in planet-warming CO2 was driven by fossil fuel burning [Talkshop comment – mere assertion], devastating wildfires and a weakening of Earth’s natural carbon stores, the Met Office said.
Scientists said at such rates, the world cannot hope to hold global warming to the 1.5C limit that nations have agreed would avert the worst consequences of climate change.
Last year the atmospheric CO2 level at the Mauna Loa observatory in Hawaii, which has been taking such measurements for more than 60 years, spiked by 3.58 parts per million (ppm).
This blew past the Met Office’s prediction of 2.84 ppm and even the uppermost range of its estimate at 3.38 ppm.
“Satellite measurements also showed a very large rise across the globe, due to the impact of record high emissions from fossil fuel burning being magnified by weaker natural carbon sinks –- such as tropical forests—and exceptional wildfires,” the meteorological agency said.
The Mauna Loa readings, known as the Keeling Curve, date back to 1958 and are the longest-running dataset of atmospheric CO2 concentrations.
