Data from the World Meteorological Organization (WMO) released this Wednesday (15) indicate that carbon dioxide (CO²) levels in the atmosphere reached new records throughout 2024.
According to the Greenhouse Gas Bulletin Report, carbon dioxide levels in the atmosphere impact the climate not only today, but for many centuries.
The United Nations (UN) agency also warned that, due to the increase in CO² levels in the atmosphere, the world is likely to experience even higher temperatures and more extreme weather phenomena.

In the document, the WMO reinforces actions to monitor carbon dioxide levels in the atmosphere, classifying the strategy as vital for actions to be taken to contain its impacts.
Report coordinator and WMO senior scientific director Oksana Tarasova highlighted that there is concern that land-based and oceanic carbon dioxide sinks are becoming less effective, which would increase the amount of carbon dioxide remaining in the atmosphere, accelerating global warming.
“The global monitoring of greenhouse gases coordinated by the WMO is more important than ever to understand the consequences of less effective CO² sinks”, informed the entity.

Understand
A carbon sink is a natural or artificial system that absorbs more carbon dioxide from the atmosphere than it emits. They play an essential role in climate regulation, helping to remove carbon dioxide from the atmosphere and store it, contributing to the mitigation of climate change.
The main natural carbon sinks include forests, oceans and soils. Forests, through photosynthesis, capture CO² and store it in their biomass. Soils, especially those rich in organic matter, also accumulate carbon in their layers. The oceans absorb large amounts of CO²¹ through their marine ecosystems, which include aquatic plants and animal life, a process known as blue carbon.
The Amazon, for example, is one of the world’s main carbon sinks.
