Carbon dioxide levels increase by record amount to new highs in 2024
The WMO Greenhouse Gas Bulletin said continued emissions of CO2 from human activities and an upsurge from wildfires were responsible, as well as reduced CO2 absorption by “sinks” such as land ecosystems and the ocean – in what threatens to be a vicious climate cycle.

The amount of CO2 in the atmosphere increased by a record amount last year, says @wmo-global.bsky.social.

The record annual rise comes amid growing signs that forests, peatlands, oceans and other natural "sinks" are failing to absorb as much CO2 as they normally do.

"Disasters are becoming more frequent, more costly, and more devastating. While direct disaster costs have grown to approx. $202B annually, the Disaster Risk Reduction report 2025 estimates that the true cost, is 11 times higher at nearly $2.3T."

Current 12-month running mean above preindustrial is 1.51°C

“Several systems (land permafrost, Greenland ice sheet, West Antarctic ice sheet and sub-polar gyre) likely have a tipping point around 1.5°C global warming.”
