Over the last decade, humanity’s emissions of carbon dioxide (CO₂) have stabilized after a period of huge growth. Average growth is now down to just 0.6% per year, compared to 2% per year in the previous decade. But leveling off isn’t the same as declining—and we’ve leveled off at a very high rate of emissions. The Global Carbon Project estimates human activities released a record high of 10.2 gigatons of carbon (GtC) in 2024. …CO₂ concentrations are increasing because we are still pumping massive amounts of long-buried CO₂ into our atmosphere. …natural carbon sinks are struggling to keep up. …This is a crucial moment. Our current rate of emissions will only cause CO₂ concentrations and global temperatures to rise. Natural carbon sinks will not pull out enough carbon to stabilize our climate on a timeframe meaningful to humans. The earlier the action and decrease in emissions, the better our future.
