A new report indicates that a major carbon sink may have disappeared for the second consecutive year due to record-breaking heat in 2024. Terrestrial ecosystems, which typically absorb significant amounts of carbon dioxide, are now emitting nearly as much CO2 as they are capturing. This alarming trend suggests a weakening of the planet's natural ability to mitigate climate change. Scientists are concerned that this shift could accelerate global warming and further destabilize climate patterns, underscoring the urgent need for increased efforts to reduce greenhouse gas emissions and protect vulnerable ecosystems.
