For the first time in history, atmospheric_CO2 exceeds 430 ppm

CO₂, the main greenhouse gas, continues its upward curve in history.

For decades, scientists have warned about the impact of increased carbon dioxide (CO₂) in the atmosphere. However, on March 7, 2025, a threshold was crossed that reinforces the urgency to take action. The Mau-na Loa Observatory in Hawaii recorded 430.6 parts per million (ppm), the highest figure in at least three million years in human history. This data not only confirms the acceleration of global warming, but also shows that time to act is running out. Even if fossil fuels were no longer burned today, decades and decades of massively expelling greenhouse gases from coal, oil and gas would cause the planet’s global temperature to continue to rise. This is due to the concentration of carbon dioxide (a gas responsible for 64% of global warming) in the atmosphere, a value that has not stopped rising since the industrial revolution and that goes hand in hand with the increase in temperature. The Mauna Loa Observatory, ultimately dependent on the National Oceanic and Atmospheric Administration (NOAA) – an agency that is dismantling the Trump administration – is the oldest CO₂ measurement station in operation, making it the world reference in this field.
