Understanding the Decline of Earth’s Carbon Dioxide Absorption: A Historical Look at Environmental Changes – Noticias Ambientales

Carbon dioxide (CO2) levels in the atmosphere hit a record high in 2024, marking the largest increase since 1957. The World Meteorological Organization (WMO) highlighted that this uptick signals a risk of more severe global warming and extreme weather events.

In 2024, average CO2 concentrations soared to 423.9 parts per million (ppm), a stark rise from 377.1 ppm just two decades ago. This marks a jump of 3.5 ppm from 2023, the largest annual increase observed. According to climate scientists, this trend is extremely troubling and underscores an urgent need for action.

The rise in CO2 levels is driven by human activities and intensified forest fires. Experts note that since the 1960s, the rate of CO2 accumulation has tripled. In the 1960s, the average annual increase was 0.8 ppm; today, it has surged to 2.4 ppm.

The UN’s findings indicate that about half of the CO2 we emit remains in the atmosphere. The other half is absorbed by oceans and land. However, this absorption is weakening. As temperatures rise, oceans can hold less CO2, and drought conditions hamper the land’s capacity to absorb carbon.

Forest fires have also contributed to these alarming trends. WMO’s report indicates that the 2024 increase was exacerbated by a significant rise in forest fires and diminished absorption capabilities, particularly influenced by the El Niño phenomenon.

Additionally, 2024 set records not just for CO2 but also for methane and nitrous oxide, two other prevalent greenhouse gases. Methane levels reached 1,942 parts per billion (ppb), over 166% higher than pre-industrial levels, while nitrous oxide hit 338 ppb, 25% more than before industrialization.

Long-term impacts on climate due to rising greenhouse gases are significant. The WMO emphasizes that the effects of increased CO2 can last for centuries. WMO’s Deputy Secretary-General, Ko Barrett, warned that reducing emissions is crucial for both environmental and economic health.

As more people share their concerns on social media about climate change, it’s clear that a collective effort is necessary. Communities and nations must respond urgently to mitigate greenhouse gas emissions and ensure a healthier planet for future generations.
