We are told ocean acidity has increased by 30% in two centuries. But oceans aren’t acidic; they are alkaline. On the pH scale, 7.0 is neutral. The oceans have shifted from roughly 8.2 to 8.1 in 200 years - remaining firmly alkaline. So where does 30% come from? The pH scale is logarithmic. A tiny decimal shift represents a 30% change in hydrogen ion concentration, but the water itself is nowhere near becoming an acid. It’s a classic case of math creating psychological exaggeration. Using boron isotope proxies in ancient shells, paleoclimatologists track ocean chemistry back millions of years. The record shows oceans thrived under much higher CO₂ and lower pH levels in the deep geological past. The 'dissolving' narrative ignores the ocean's scale. With an average depth of 2.35 miles and 1.3 billion cubic kilometers of water, the ocean possesses massive chemical inertia. Atmospheric changes take centuries to even reach the deep abyss. Marine life is remarkably resilient. Many species actually calcify faster in CO₂-rich environments. The oceans are not a fragile bowl of acid; they are a vast, self-regulating engine that has remained resilient for millennia. #ClimateNuance #Oceanography #NASA #Greening – at Bega, New South Wales

UN Secretary-General António Guterres has frequently said the Earth is 'out of balance' due to heat trapped in the atmosphere. This ignores basic thermodynamics. Guterres says the planet is experiencing an era of 'global boiling'. This is not possible. The atmosphere cannot act as a permanent heat vault. It's a low-density medium with negligible mass and it sheds thermal energy to space every night. The true thermal engine of the planet is the ocean - a 1.3 billion cubic km body of water with 1,000 times the heat capacity of the air. On a clear night, that energy escapes into the vacuum of space at the speed of light. Every molecule in the air radiates infrared energy and without the sun’s shortwave input at night, the atmosphere sheds heat upward. The residence time of atmospheric heat is fleeting. We see this every day. Once the sun sets, air temperatures can drop 10°C to 20°C in hours. The atmosphere has almost no memory of heat. If the sun turned off, the air would lose its warmth in weeks, but the oceans would take millennia. Wind and convection further speed this up, carrying warm air to higher altitudes where the atmospheric blanket is thinnest. This makes it even easier to radiate away. To focus on heat 'trapped' in the air is a fundamental error in scale. #Thermodynamics or #ClimateNuance – at Bega, New South Wales
