CO₂ Keeps Climbing – Faster Than We Think
CO₂ Keeps Climbing – Faster Than We Think A few weeks ago, the atmospheric CO₂ reading at Mauna Loa Observatory quietly passed 430 parts per million (ppm) . Now? We’re already at 432.5 ppm . What Does That Actually Mean? This isn’t just a number ticking up on a scientist’s screen. It’s part of the famous Keeling Curve – one of the clearest pieces of evidence we have that human activity is changing the atmosphere. Pre-industrial CO₂: ~280 ppm 2000: ~370 ppm 2015: ~400 ppm 2026: 432.5 ppm… and rising fast That’s not a gentle slope anymore — it’s starting to look like a ramp. Why This Matters CO₂ is a greenhouse gas. More CO₂ = more heat trapped. We’re already seeing the effects: Hotter summers (and not just “nice BBQ weather”) Warmer oceans absorbing excess heat More extreme weather events Shifts in ecosystems (including those freshwater fish collapses we talked about recently) The worrying bit? The rate of increase is accelerating. “It’s Only a Few Parts Per Million…” That sounds tin...
