Carbon dioxide levels in the atmosphere jumped by a record amount in 2024, reaching the highest concentration ever measured and locking the planet into more long-term warming, the UN weather agency warned on Wednesday.
The World Meteorological Organisation (WMO) said the rise was fuelled by human-caused emissions, massive wildfires and a drop in the ability of forests and oceans to absorb carbon – a feedback loop that scientists fear could make climate change spiral faster.
