WMO warns of extreme weather as CO2 levels reach highest level ever recorded

A new report from the World Meteorological Organization shows that carbon dioxide levels have risen to their highest level ever. This could lead to a further increase in global warming and more extreme weather events. The report found that between 2023 and 2024 the average global CO2 concentration rose by 3.5 parts-per-million, which is the biggest increase since modern measurements began in 1957.

It said that the increase in CO2 over the past year was due to the burning of fossil fuels as well as an increase in wildfires in South America. The report also stressed the need to do more to reduce emissions.

Ko Barrett, WMO's Deputy Secretary General, said that the heat trapped by CO2 or other greenhouse gases was causing our climate to be more extreme and accelerating it.

The concentrations of methane, nitrous oxide and other important greenhouse gasses, such as nitrous dioxide, have also reached record highs, with increases of 16% and 24% respectively compared to pre-industrial levels. CO2 has increased by 52%.

This gas (CO2) accumulates. It is very long-lasting... each molecule that is released into the atmosphere has an impact on the world," Oksana TARASOVA, WMO senior scientist officer, said at a Geneva briefing.

Tarasova stated that forests, land and oceans absorb about 50% of the carbon dioxide emissions. However, their ability to do so is decreasing.

Tarasova stated that "we rely on the natural systems to offset our impacts and they are so stressed, they begin to reduce their help." Tarasova said that trees in the Amazon became stressed by the rising temperatures and low rain during the periodic warming of the Eastern Pacific Ocean, known as El Nino, in 2023. The drought continued until 2024.

She said, "If a tree is stressed out or has no water and a high temperature...it will not photosynthesize." (Reporting and editing by Sharon Singleton; Olivia Le Poidevin)
